Similarly, form data is typically saved in a database on the server.

Finally, notice that instead of using "text" as the input type for the email and url fields, we use "email" and "url".

This will buy us free validation from browsers that support HTML5 even if Java Script is turned off.

By validating form responses before accepting them, we can alert users to their errors before they submit the form.

In this way, client side form validation can vastly improve the user experience.

Instead, I'd go with a few basic points to pretty accurately represent it, and then describe the rest.

Here's a few things (non-exhaustive list) you could include in a condition for email validation (set all conditions must be true): If value Email index Of('@') is greater than or equal to…

If the data is valid the input box should be green.

If the data is invalid, the input box should be red.

If you validate the form using j Query, you can notice this and alert the user to their mistake instead of submitting the form.

Java Script form validation is a great way to help your users avoid mistakes when filling out a form Alternatively, if you want to protect your server from malicious users, then you should use server side validation because Java Script can be easily bypassed.

You cannot rely on Java Script to avoid this security problem. You can also download this demo and check out the source as we go through this tutorial.
