Validating fields in html
The form in HTML will look like this: tag improves usability.
Clicking on the label will move the mouse cursor to the input with the id specified in the for attribute.
Your brace should be after function validate Form() and after the if, and at the end of the function. Lay your code out so the opening and closing braces match up and make sense to you.
By validating form responses before accepting them, we can alert users to their errors before they submit the form.
If it exists, we'll apply the valid class and remove any invalid class.
This will place a green border around the input box.
The name of each input (or textarea) will be passed to the server to identify the contents of the form.
Finally, notice that instead of using "text" as the input type for the email and url fields, we use "email" and "url".
When the submit button is pushed, j Query will check whether all fields are valid.We also want to implement real-time validation where the color of the input will change based on the validity of the data that has been entered.If the data is valid the input box should be green.To avoid this problem, you must validate form submissions using your server.You cannot rely on Java Script to avoid this security problem.
