#11296 closed bug (invalid)

$ selector for base64'd id

Reported by: [email protected] Owned by: [email protected]
Priority: undecided Milestone: None
Component: unfiled Version: 1.7.1
Keywords: Cc:
Blocked by: Blocking:


I have rows of data in a table, each row have an id that's basically an base64'd string for the appropriate item's key in a huge array collection.

Basically, if I do this:


there's one exact and correct match.

But when doing this:


nothing returned

I checked the problematic html structures through W3 HTML validator as HTML5 DOCTYPE, and it passed, so I assumed that using base64'd string as an element ID is valid.

I really hate to submit this as a bug, but I have nowhere else to ask, although I'd probably end up using document.getElementId, I guess there's no harm mentioning this to the jQuery's dev team :)

Try StackOverflow or http://forum.jquery.com .

Hint: "=" is a special character.

workaround: $("[id='MU4yRC50eHQ=']") will select your div

You're using the wrong validator. Treat the jQuery constructor like document.querySelectorAll, not like document.getElementById. Special characters must be escaped:
