.hasClass() as well for ids etc.?

Hi there,

I was wondering whether it is possible to use the .hasClass(); method for CSS-ids, names etc. as well?

For example:

<div id="id-name">
<p>insert text here</p>

And then try to add changes via jQuery like this:

if($("p").parent().hasClass("id-name")) {
// insert condition here

If not - what would be an alternative for that then?

Thanks for your help!

I don't think it works, but even if it does, it'd be a bit of a roundabout way of selecting an element based on its ID. You could use .attr().

Because each ID on a page should only belong to one element, using normal CSS selectors would work. What specifically would you like to do with the paragraph?

$("#id-name p")

Actually, that was just a fully random example. This question just popped into my mind while watching this video, but I agree with your comment and solution - this makes more sense! :-)
