JavaScript Form Validation : quick and easy!

Using client side JavaScript is an efficient way to validate the user input in web forms. When there are many fields in the form, the JavaScript validation becomes too complex.

The JavaScript class presented here makes the form validations many times easier.

How to add JavaScript Form Validation quickly

First, download the JavaScript form validation script here.
The zip file contains the javascript file, examples.

The script has a catalog of almost all the common validation types built-in.

The idea is to create a set of “validation descriptors” associated with each element in a form. The “validation descriptor” is nothing but a string specifying the type of validation to be performed.

Each field in the form can have zero one or more validations. For example, you can have an input field that should not be empty, should be less than 25 chars and should be alpha-numeric.

In other words, in order to validate a field, you just associate a set of validation descriptors for each input field in the form.

You just have to choose the validations. More info & downloads

Using the form validation script

1. Include gen_validatorv4.js in your html file just before closing the HEAD tag

<script src="gen_validatorv4.js" type="text/javascript"></script>

</head>

1. Just after defining your form, create a Validator() object passing the name of the form

<form id='myform' action="">

<!----Your input fields go here -->

</form>

<script type="text/javascript">

var frmvalidator  = new Validator("myform");

//where myform is the name/id of your form

1. Now, add the validations required

frmvalidator.addValidation("FirstName","req","Please enter your First Name");

The format of the addValidation() function is:

frmvalidator.addValidation(Field Name, Validation Descriptor, Error String);

See below for the complete list of validation descriptors. The third parameter ( Error string ) is optional.
You can add any number of validations to a field.

frmvalidator.addValidation("FirstName","req","Please enter your First Name");

frmvalidator.addValidation("FirstName","maxlen=40",

"Max length for FirstName is 40");

Example

Here is a complete example:

<form action="" id="myform" >

<p>

<label for='FirstName'>First Name:</label>

<input type="text" id="FirstName" name="FirstName" />

</p>

<p>

<label for='LastName'>Last Name:</label>

<input type="text" id="LastName" name="LastName" />

</p>

<p>

<label for='EMail'>EMail:</label>

<input type="text" id="EMail" name="EMail" />

</p>

<p>

<label for='Phone'>Phone:</label>

<input type="text" id="Phone" name="Phone" />

</p>

<p>

<label for='Address'>Address:</label>

<textarea cols="20" rows="5" id="Address" name="Address"></textarea>

</p>

<p>

<label for='Country'>Country:</label>

<select id="Country"  name="Country">

<option value="000" selected="selected">[choose yours]</option>

<option value="008">Albania</option>

<option value="012">Algeria</option>

<option value="016">American Samoa</option>

<option value="020">Andorra</option>

<option value="024">Angola</option>

<option value="660">Anguilla</option>

<option value="010">Antarctica</option>

<option value="028">Antigua And Barbuda</option>

<option value="032">Argentina</option>

<option value="051">Armenia</option>

<option value="533">Aruba</option>

</select>

</p>

<p>

<input type="submit" name="submit" value="Submit">

</p>

</form>

<script  type="text/javascript">

var frmvalidator = new Validator("myform");

frmvalidator.addValidation("FirstName","req","Please enter your First Name");

frmvalidator.addValidation("FirstName","maxlen=20",

"Max length for FirstName is 20");

frmvalidator.addValidation("LastName","req");

frmvalidator.addValidation("LastName","maxlen=20");

frmvalidator.addValidation("Email","maxlen=50");

frmvalidator.addValidation("Email","req");

frmvalidator.addValidation("Email","email");

frmvalidator.addValidation("Phone","maxlen=50");

frmvalidator.addValidation("Phone","numeric");

frmvalidator.addValidation("Address","maxlen=50");

frmvalidator.addValidation("Country","dontselect=000");

</script>

Some Additional Notes

• The form validators should be created only after defining the HTML form (only after the tag. )
• Your form should have a distinguished name. If there are more than one form in the same page, you can add validators for each of them. The names of the forms and the validators should not clash.
• You can’t use the javascript onsubmit event of the form if it you are using this validator script. It is because the validator script automatically overrides the onsubmit event. If you want to add a custom validation, see the section below

Adding a custom validation

If you want to add a custom validation, which is not provided by the validation descriptors, you can do so. Here are the steps:

1. Create a javascript function which returns true or false depending on the validation

function DoCustomValidation()

{

var frm = document.forms["myform"];

if(frm.pwd1.value != frm.pwd2.value)

{

sfm_show_error_msg('The Password and verified password does not match!',frm.pwd1);

return false;

}

else

{

return true;

}

}

sfm_show_error_msg() function displays the error message in your chosen style. The first parameter is the error message and the second parameter is the input object.

1. Associate the validation function with the validator object.

frmvalidator.setAddnlValidationFunction("DoCustomValidation");

The custom validation function will be called automatically after other validations.

If you want to do more than one custom validations, you can do all those validations in the same function.

function DoCustomValidation()

{

var frm = document.forms["myform"];

if(false == DoMyValidationOne())

{

sfm_show_error_msg('Validation One Failed!');

return false;

}

else

if(false == DoMyValidationTwo())

{

sfm_show_error_msg('Validation Two Failed!');

return false;

}

else

{

return true;

}

}

where DoMyValidationOne() and DoMyValidationTwo() are custom functions for validation.

Clear All Validations

In some dynamically programmed pages, it may be required to change the validations in the form at run time. For such cases, a function is included which clears all validations in the validator object.

frmvalidator.clearAllValidations();

This function call clears all validations you set.

Set focus on validation failure

By default, if there is a validation error, the focus is set on the input element having the error. You can disable this behavior by calling:

frmvalidator.EnableFocusOnError(false);

Table of Validation Descriptors

Validation Descriptor	Usage
required or req	The field should not be empty.Note that this validation if for fields like Textbox and multi-line text box. For ‘selections’ like drop down and radio group, use an appropriate validation like ‘dontselect’ or ‘selone_radio’.
maxlen=??? or maxlength=???	Limits the length of the input. For example, if the maximum size permitted is 25, give the validation descriptor as “maxlen=25″
minlen=??? or minlength=???	Checks the length of the entered string to the required minimum. Example “minlen=5″
alphanumeric or alnum	The input can contain alphabetic or numeric characters only. (Note that space or punctuation also are not allowed since those characters are not alpha numeric)
alphanumeric_space alnum_s	Allows only alphabetic, numeric and space characters
num numeric	Allow numbers only
alpha alphabetic	Allow only alphabetic characters.
alpha_s alphabetic_space	Allows alphabetic and space characters
email	Validates the field to be a proper email address. (Note, However that the validation can’t check whether the email address exists or not)
lt=??? lessthan=???	Verify the data to be less than the value passed. Valid only for numeric fields. Example: if the value should be less than 1000 give validation description as “lt=1000″
gt=??? greaterthan=???	Verify the data to be greater than the value passed. Valid only for numeric fields. Example: if the value should be greater than 10 give validation description as “gt=10″
regexp=???	Match the input with a regular expression. Example: “regexp=^[A-Za-z]{1,20}$” allow up to 20 alphabetic characters.
dontselect=??	This validation descriptor is valid only for drop down lists. The drop down select list boxes usually will have one item saying ‘Select One’ (and that item will be selected by default). The user should select an option other than this ‘Select One’ item. If the valueof this default option is ’000′, the validation description should be “dontselect=000″
dontselectchk=??	This validation descriptor is only for check boxes. The user should not select the given check box. Provide the value of the check box instead of ?? For example, dontselectchk=on
shouldselchk=??	This validation descriptor is only for check boxes. The user should select the given check box. Provide the value of the check box instead of ?? For example, shouldselchk=on
selone_radio	One of the radio buttons should be selected. Example: chktestValidator.addValidation("Options","selone");
Compare two input elements
eqelmnt=???	Compare two input elements. For example: password and confirm password. Replace ??? with the name of the other input element. Example: frmvalidator.addValidation("confpassword","eqelmnt=password",  "The confirmed password is not same as password");
neelmnt=???	The value should not be equal to the other input element Example: frmvalidator.addValidation("password","neelmnt=username", "The password should not be same as username");
ltelmnt=???	The input should be less than the other input. Give the name of the other input instead of ???
leelmnt=???	The input should be less than or equal to the other input. Give the name of the other input instead of ???
gtelmnt=???	The input should be greater than the other input. Give the name of the other input instead of ???
geelmnt=???	The input should be greater than or equal to the other input. Give the name of the other input instead of ???

5 Examples of when to use silence ?

1. During arguments. One of the best times to use the power of silence is during  an argument is to stay silent. The ego will be trying to force its way out of you and finish the argument but you are the controller, not the ego. When someone is shouting at you, looking for an argument or just picking on you can literally take all the power away from them and keep all your energy by simply looking at them and saying absolutely nothing. This is extremely difficult to do but very powerful.

2. Gossiping. When there is a crowd of people in the workplace there are gossipers who speak about other people. The thing with gossiping is that it is contagious. When we don’t like someone and someone else starts speaking about them we naturally tend to voice our opinion, I’ve done it lots of times and have to stop myself.

Try and stop yourself from catching the virus of gossiping and use the power of silent whenever it occurs. If you are a gossiper yourself and people around start to notice that you are ‘not your usual self’, don’t give an explanation just leave saying you’ve got work to do or whatever, pretty soon you’ll be out of the gossiping loop.

3. When someone is talking. Silence is a great tool for counselors if used in the right way. It’s also great when listening to friends and family.

Just let people talk and listen to them and use your facial expressions and movements to acknowledge that you are listening. This can be a tough thing to do but extremely powerful for both you, as the listener, and the talker.

You will find that as you practice this, more people come to talk to you as you will be known as a listener. Obviously there are times to speak during the conversation, however when you do, make sure it is to paraphrase what the talker is saying or asking questions to get more information, don’t make it about yourself.

When people want to know more about you they will ask you questions, this is the time to talk about yourself but always have the listener be part of the conversation.

4. When the house is empty. The silence of the home can be quite disturbing to some people as there is a natural need to fill the void of silence. We turn on the radio, play some music, call friends or family, or turn on the TV to fill this void. Having a completely silent home when you are alone does not mean you are alone it simply means you are recharging your mind and giving it some downtime.

Silence helps us to work through, in our minds, the events of the day or project what we want to happen during the day ahead. I am a night owl and also a morning lark. I love the silence when I know everyone is safe and tucked up in bed and I can write or work on the computer. At the weekends I go to bed with my wife to talk about days events or our plans and just have a laugh or whatever. My wife, who loves her sleep, has gone to sleep I kiss her goodnight and get up for a few hours to write as this is the time I am most inspired. I am also the first person up in the morning which means I have another 2 hours to write or work on my online projects.

I know it’s harder when you are alone, however silent time can be used to think about the life you want and work out ways to get it.

5. Quiet reflection. This is a fantastic way to connect with world in a way that is not possible when you are surrounded by hubbub noise. 15 minutes in the morning, 15 minutes in the evening simply focusing on your breath can do wonders for both mind and body. I truly believe that with practice quiet reflection can help us reach a level of deep inner calm.

The state of silence is a way of reaching another part of your mind not possible when going about your daily routine. This other part of your mind is connected in every way to the world around you and with practice you can tap into this knowledge.

Web Services – Web Services Tutorials

In this section of the Web Services tutorial you will be familiarized with the Web Services.

Introduction

The next generation of distributed computing has arrived. A Web service is a unit of managed code that can be remotely invoked using HTTP, that is, it can be activated using HTTP requests.

Historically speaking, remote access to binary units required platform-specific and sometimes language-specific protocols. For example, DCOM clients access remote COM types using tightly coupled RPC calls. CORBA requires the use of tightly coupled protocol referred to as Internet Inter-ORB Protocol (IIOP), to activate remote types. Enterprise JavaBeans (EJBs) requires a Remote Method Invocation (RMI) Protocol and by and large a specific language (Java). Thus each of these remote invocation architectures needs proprietary protocols, which typically require a tight connection to the remote source.

One can access Web services using nothing but HTTP. Of all the protocols in existence today, HTTP is the one specific wire protocol that all platforms tend to agree on. Thus , using Web services, a Web service developer can use any language he wish and a Web service consumer can use standard HTTP to invoke methods a Web service provides. The bottom line is that we have true language and platform integration . Simple Object Access Protocol (SOAP) and XML are also two key pieces of the Web services architecture.

What is a Web Service

Web services constitute a distributed computer architecture made up of many different computers trying to communicate over the network to form one system. They consist of a set of standards that allow developers to implement distributed applications – using radically different tools provided by many different vendors – to create applications that use a combination of software modules called from systems in disparate departments or from other companies.

A Web service contains some number of classes, interfaces, enumerations and structures that provide black box functionality to remote clients. Web services typically define business objects that execute a unit of work (e.g., perform a calculation, read a data source, etc.) for the consumer and wait for the next request. Web service consumer does not necessarily need to be a browser-based client. Console-baed and Windows Forms-based clients can consume a Web service. In each case, the client indirectly interacts with the Web service through an intervening proxy. The proxy looks and feels like the real remote type and exposes the same set of methods. Under the hood, the proxy code really forwards the request to the Web service using standard HTTP or optionally SOAP messages.

Web Service Standards

Web services are registered and announced using the following services and protocols. Many of these and other standards are being worked out by the UDDI project, a group of industry leaders that is spearheading the early creation and design efforts.

Universal Description, Discovery, and Integration (UDDI) is a protocol for describing available Web services components. This standard allows businesses to register with an Internet directory that will help them advertise their services, so companies can find one another and conduct transactions over the Web. This registration and lookup task is done using XML and HTTP(S)-based mechanisms.

Simple Object Access Protocol (SOAP) is a protocol for initiating conversations with a UDDI Service. SOAP makes object access simple by allowing applications to invoke object methods or functions, residing on remote servers. A SOAP application creates a request block in XML, supplying the data needed by the remote method as well as the location of the remote object itself.

Web Service Description Language (WSDL), the proposed standard for how a Web service is described, is an XML-based service IDL (Interface Definitition Language) that defines the service interface and its implementation characteristics. WSDL is referenced by UDDI entries and describes the SOAP messages that define a particular Web service.

ebXML (e-business XML) defines core components, business processes, registry and repository, messaging services, trading partner agreements, and security.

Implementing Web Services

Here comes a brief step-by-step on how a Web service is implemented.

• A service provider creates a Web service
• The service provider uses WSDL to describe the service to a UDDI registry
• The service provider registers the service in a UDDI registry and/or ebXML registry/repository.
• Another service or consumer locates and requests the registered service by querying UDDI and/or ebXML registries.
• The requesting service or user writes an application to bind the registered service using SOAP in the case of UDDI and/or ebXML
• Data and messages are exchanged as XML over HTTP

Web Service Infrastructure

Even though Web services are being built using existing infrastructure, there exists a strong necessity for a number of innovative infrastructures. The core architectural foundation of Web services are XML, XML namespaces, and XML schema. UDDI, SOAP, WSDL, ebXML and security standards are being developed in parallel by different vendors

Web Services Technologies and Tools

There are a number of mechanisms for constructing Web services. Microsoft has come out with a new object-oriented language C# as the development language for Web services and .NET framework. Microsoft has an exciting tool called Visual Studio .NET in this regard. The back end database can be Microsoft SQL Server 2000 in Windows 2000 Professional.

Sun Microsystems has its own set of technologies and tools for facilitating Web services development. Java Servlets, Java Server Pages (JSPs), Enterprise JavaBeans (EJB) architecture and other Java 2 Enterprise Edition (J2EE) technologies play a very critical role in developing Web services.

There are a number of tools for developing Web services. They are Forte Java IDE, Oracle JDeveloper, and WebGain Studio.

Sun Microsystems has taken an initiative called Sun ONE (Open Network Environment) and is planning to push Java forward as a platform for Web services. It is developing Java APIs for XML-based remote procedure calls and for looking up services in XML registries – two more JAX family APIs: JAX/RPC (Java API for XML Remote Procedure Calls) and JAXR (Java API for XML Registries). These will wrap up implementations of Web services standards, such as SOAP and UDDI.

IBM also for its part has already developed a suite of early-access tools for Web services development. They are Web Services Toolkit (WSTK), WSDL Toolkit, and Web Services Development Environment (WSDE).

Apache Axis is an implementation of the SOAP (“Simple Object Access Protocol”) submission to W3C.

From the draft W3C specification:

SOAP is a lightweight protocol for exchanging structured information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelope that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing remote procedure calls and responses.

Apache Axis is an Open Source SOAP server and client. SOAP is a mechanism for inter-application communication between systems written in arbitrary languages, across the Internet. SOAP usually exchanges messages over HTTP: the client POSTs a SOAP request, and receives either an HTTP success code and a SOAP response or an HTTP error code. Open Source means that you get the source, but that there is no formal support organization to help you when things go wrong.

Conclusion

For the last few years, XML has enabled heterogeneous computing environments to share information over the Web. It now offers a simplified means by which to share process as well. From a technical perspective, the advent of Web services is not a revolution in distributed computing. It is instead a natural evolution of XML application from structured representation of information to structured representation of inter-application messaging.

Prior to the advent of Web services, enterprise application integration (EAI) was very difficult due to differences in programming languages and middleware used within organizations. This led to the situation where interoperability was cumbersome and painful. With the arrival of Web services, any application can be integrated as long as it is Internet-enabled.

It is difficult to avoid the popularity and hype that is surrounding Web services. Each software vendor has some initiative concerning Web services and there is always great speculation about the future of the market for them. Whichever way it turns out, Web service architectures provide a very different way of thinking about software development. From client-server to n-tier systems, to distributed computing, Web service applications represent the culmination of each of these architectures in combination with the Internet.

2. Enter
   name as ?WebServiceTutorial?, select project location as ?E:\Test?
   and select Apache Tomcat v5.5 as the Target server. 

 

 

 

3. Now
   create a new Java class from the Project Explorer (Dynamic Web Projects
   -> Java Source -> New -> Class) 

 

 

 

4. Enter
   name as ?Hello? and package as ?com.tutorial?. 

 

 

5. Add
   a simple method in the ?Hello? class as below. 

public String sayHello(String name){

 

return “Hello ” + name;

 

}

 

 

 

6. Save
   and build the project.

10. Select
    Overwrite files without warning. 

 

 

11. Select
    or enter the Bean name as ?com.tutorial.Hello?. This is the java class
    that we just now created. 

 

 

12. Continue
    the wizard by clicking Next and finish. 
13. On
    Finish, the Tomcat server starts up and launches the Test client. 
14. Verify
    the generated contents. Look for Hello.class and the generated JSPs as
    below. 

 

 

 

 

 

15. Verify
    the Tomcat folder and ensure the newly created web applications ?
    WebServiceTutorial, WebServiceTutorialClient. 

 

 

 

 

16. We
    can also run the following url from the browser to access/test the Web
    service. 

http://localhost:8080/WebServiceTutorialClient/sampleHelloProxy/TestClient.jsp

 

 

17. If
    servlet error ?org.eclipse.jst.ws.util.JspUtils cannot be resolved or is
    not a type? is thrown on the browser, then copy the webserviceutils.jar
    file from the E:\Eclipse3.1\eclipse\plugins\org.eclipse.jst.ws.consumption_0.7.0
    into the WEB-INF\lib folder of the WebServiceTutorialClient application and
    restart the Tomcat server. 

18. The
    browser displays the methods available in the web service. 

 

 

 

19. Click
    on the sayHello(..) method, enter your name (for e.g. ?Jeeva?) in
    the inputs section and click ?Invoke?. 

 

 

 

20. The
    browser greets using the web service. 

 

 

 

 

 

21. The
    WSDL for the Hello Web service can be found in E:\Test\WebServiceTutorial\WebContent\wsdl\Hello.wsdl.
    On double-click, the WSDL opens in a graphical editor. 

 

 

 

22. Right-click
    on the WSDL file and explore the options to test the web service / publish
    the WSDL file / generate client / etc.
