Question

I want to add some image background if my input has class valid.

I read documentation, read some stackoveflow questions ( like this -> hasClass doesn't work in my js code? ), but I’m failing to implement it in my modal.

Here is jsfiddle with all HTML and js -> http://jsfiddle.net/33PGQ/34/

Can someone suggest what is wrong ?

P.S.Also tried to write in hasClass function like this: div > form > …( did not work )

Answer 1

The issue is not hasClass method, you selector is wrong, you should use . for class selectors, jQuery selectors work like CSS selectors.

$('.modal .form_for_login form .field2  input');
