Solution 1:

This problem can also arise if you include jQuery more than once.

Ignore me. I'm sorry everyone. I'd mistyped the url of the script. Thanks to Simon Ainley for the prod in the right direction.

Sorry again. Thanks.

Solution 3:

I had this problem, or one that looked superficially similar, yesterday. It turned out that I wasn't being careful when mixing jQuery and prototype. I found several solutions at http://docs.jquery.com/Using_jQuery_with_Other_Libraries. I opted for

var$j = jQuery.noConflict();

but there are other reasonable options described there.

Solution 4:

For anyone else arriving at this question:

I was performing the most simple jQuery, trying to hide an element:

('#fileselection').hide();

and I was getting the same type of error, "Uncaught TypeError: Object #fileselection has no method 'hide'

Of course, now it is obvious, but I just left off the jQuery indicator '$'. The code should have been:

$('#fileselection').hide();

This fixes the no-brainer problem. I hope this helps someone save a few minutes debugging!

Solution 5:

This problem may also come up if you include different versions of jQuery.
