Code for validating email in javascript

This is handy because we don’t really want to allow our user to submit a form with invalid data.Once the form is validated on the server side, it should spit it back out with an error message.event allows you to run Javascript code when the user clicks away from the field. In order to validate the input, we have to test it against a set of rules that define a pass or fail.

The validation you’ve added so far is great because it allows the user to correct their mistakes as they progress.

The next step is to prevent the form from being submitted if any of the validation rules are broken.

This alerts the user to any errors and allows her to correct her errors before proceeding and losing her progress.

Inline validation powered by Javascript can be incredibly easy to implement, so there really is no excuse for not making your user’s lives as easy as possible.

To add a validation prompt, add the following line of code to your form, just under your input field.

This will clean up the prompt message once the user corrects their mistake.

  1. These are truisms known to anyone who has watched 10 minutes of a teen movie or spent 10 minutes in a high school cafeteria.

  2. This way, you can eliminate or lower the interest you're paying by transferring your balance from one or more cards where you are paying a high interest rate to one with a lower interest rate -- or none at all! Most cards offering a 0 percent introductory APR have a 12 to 18-month time frame.
