Question

I have this in order to replace attribute disabled with readonly and I want to know if it is possible to not do that for some classes. I want to add something like “if the input does not have class x do action”

$('input[type=text][disabled="disabled"]').removeAttr("disabled").attr("readonly", true);

Answer 1

You can use the not method to exclude elements from the matched set:

$('input[type=text][disabled="disabled"]').not(".someClass").removeAttr("disabled").attr("readonly", true);

Alternatively, you could use the :not pseudo-selector, but as the documentation states, the .not method is better “in most cases”.

As a side note, you should probably be using the prop method rather than attr, since both disabled and readonly are DOM properties.
