The message is shown to the user when reporting the problem.

If the argument is the empty string, the custom error is cleared.

Let's see how to use this API to build custom error messages.

First, the HTML: attribute to turn off the browser's automatic validation; this lets our script take control over validation.

The final thing to note is that each of the three fields has a corresponding logic (which is run on submit remember) checks for name and age only as movie is optional. Don’t forget that on a successful submission it’s going to POST to a temporary URL.The code is taken from the Stack Overflow question, How to validate email address in Java Script? This is an awesome question because it makes your most intense Facebook political/religious argument look like a slight disagreement over who makes the best beer. Here is the HTML, even though it’s really close to the first example. You can play with this example here: See the Pen form validation 2 by Raymond Camden (@cfjedimaster) on Code Pen. This tells Vue to cast the value to a number when you use it.For the third example, we’ve built something you’ve probably seen in survey apps. However, there is a bug with this feature such that when the value is blank, it turns back into a string. To make it a bit easier for the user, we also added a current total right below so they can see, in real time, what their total is. We set up the total value as a computed value, and outside of that bug I ran into, it was simple enough to setup. When I copied and pasted your code into a html file and ran it, my FF and IE spat out an error.If you put an alert() inside and just below your IF block I think you'll find the alert() inside the IF block will never be executed, hence your form is always submitted whether you check any boxes or not.

Even when validation is supported perfectly, there may be times when custom validations are needed and a more manual, Vue-based solution may be more appropriate. Beneath that there is a paragraph that shows or hides itself based on an error state.
