#ID-selector inconsistent

Reported by: pcvandam@… Owned by: pcvandam@…
Priority: low Milestone: None
Component: selector Version: 1.6.4
Keywords: Cc:
Blocked by: Blocking:

Description

In the theoretical case you have multiple elements on a page with the same ID, the following selectors give different results:

$('#id') $('div#id')

The first selector only returns the first occurence of the id, while the second will return a set of all elements with that id.

They should behave the same.

  • Component changed from unfiled to selector
  • Owner set to pcvandam@…
  • Priority changed from undecided to low
  • Status changed from new to pending

Why would ever have >1 element with the same ID?

  • Status changed from pending to new

That's not the point.

Of course it shouldn't happen, but with dynamically generated content it CAN happen. Fact is jQuery does not handle ID-selectors consistently.

Actually, it is: http://www.whatwg.org/specs/web-apps/current-work/multipage/elements.html#the-id-attribute

If you write unexpected code, unexpected things happen.

Just so you get a clearer picture, the "inconsistency" isn't jQuery's fault either: http://jsfiddle.net/rwaldron/JZ8GX/
