I this article I explain how to validate a registration form using a Java Script function.
The registration form fields are validated using a Java Script function.
In this form I am using textboxes, a dropdown list, a text area and a checkbox for validation from a Java Script function and using some extra scripting like CSS and HTML for designing the form.
So simple :) you have to use j Query Form Validation library, for your forms, call the function in script tag with specific ID or Class and follow the plugin steps, if you want to customize your Validation then you have to write some function events for Calendar, Date or more.
Otherwise a browser with Java Script disabled, or a hacker trying to compromise your site, can easily submit invalid data. The first test in the example is therefore only necessary in order to provide a different error message when the input is blank.
The purpose of a form validation script is to return a boolean value ('s to reference form fields, but that can lead to namespace conflicts and why make things more complicated than necessary.
you just have to add attribute for validation and it is very customize, you can also set your custom error message using attribute.
When form input is important, it should always be verified using a secure server-side script.
This tutorial will help you to add more functionality to your forms that leads to better user experience and better website quality.
You may also enhance your already existing forms with adding some fancy effects that are presented in this tutorial. Info: If you’d like to modify your existing forms, skip the HTML and CSS sections of this tutorial and go ahead to step number five.
Before the development of HTML5 we were using the Java Script or the other Back End language to validate our form.
But the HTML5 has changed the entire things in programming technology.
