Javascript code for validating mobile number

When the form is submitted - either by hitting Enter or clicking on the Submit button - the (the 'value' of the field called 'input' belonging to the form). In a real-life situation you will most likely have more fields to check, and more complicated conditions, but the principle remains the same.

Other form values are available using a similar syntax, although this becomes more complicated if you're using SELECT lists, checkboxes or radio buttons (see below for examples). All you need to do is extend the command is encountered, execution of the function is halted.

Client side validation Validation done in the browser before sending the form data to the server using Java Script, j Query and VBScript is called client-side validation. Let us first create the web application with two web pages We are adding two web pages because our requirement is, in the first web page there is form data to be filled in by the user and only after validating the form data, the form will be redirected to the next page.

Server Side Validation Validation done at the server level after sending the form data to the server but before entering the data into the database is called server-side validation. The first page source code Look at the preceding source code closely; see the id's of controls that play the important role in Java Script validation by reading the ASP. The design view of the preceding source code will look as in the following: I hope you have created the same form as above for demonstration purposes. Net controls values in Java Script are as: There are three main methods shown in the above image in the red square to read the ASP.

Validating form input with Java Script is easy to do and can save a lot of unnecessary calls to the server as all processing is handled by the web browser.

When form input is important, it should always be verified using a secure server-side script.All of the above attributes also allow you to specify an error message that is displayed in the event of an error.If an error message is not specified, a default error message is displayed.This tutorial will show you how to create a Java Script-enabled form that checks whether a user has filled in the form correctly before it's sent to the server. First we'll explain why form validation is a useful thing, and then build up a simple example form, explaining things as we go along.At the end, there's a little exercise to keep you busy too!
