Answer 1

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.

Answer 2

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!

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.

This usually has to do with a selector not being used properly. Check and make sure that you are using the jQuery selectors like intended. For example I had this problem when creating a click method:

$("[editButton]").click(function () {
    this.css("color", "red");
});

Because I was not using the correct selector method $(this) for jQuery it gave me the same error.

So simply enough, check your selectors!

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

Answer 6

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