Question

I know the input have the maxlength, but I would like to have minlength as my personal application for define, can I have this abilities? of course, the behavior is implemented by javascript, instead of the browser, can I do so?

Answer 1

Yes, you can do that.

To make it validate with HTML5, prefix your custom attribute with data-.

You can get the minlength attribute in JavaScript with…

var minLength = +inputElement.getAttribute('data-minlength');
