Question

I need jQuery to add a class to any form element that has no class allready. I made up a function, the hasNoClass.

Is it possible to do in the real life?
Pseudo code: add class to “classless” form tag
jQuery(“form”).hasNoClass().addClass(“gotClass”);

Alternatively it can be done by a “add class to 3rd form start tag on page. No clue how that would be either, but there may be a position or count function
Pseudo code: add class to third form tag:
jQuery(“form”).postition(“3”).addClass(“gotClass”);

Wow! That was two questions! I only need the one but answer on both would be appreciated just for the sake of knowing and maybe future use.

Answer 1

This should do:

$('*:not([class])')

You’d then be able to do

$('*:not([class])').addClass('gotClass');

or

$('*:not([class])').eq(3).addClass('gotClass');

To clarify: the selector matches all elements, *, that are not within the scope: “any element with the attribute, [,], class“
