Question

I’m working on a tooltip plugin for jQuery, and I’d like to use the .data method to check if a tooltip has already been opened for the attached object. Right now I’m getting the following error out of the console:

Uncaught TypeError: Object # has no method ‘data’

Here is a paste of my plugin: http://pastebin.com/nsrBCb2Y

If I use the exact example from the jQuery website it works (the $(‘body’).data() one) but it seems like using this.data() causes problems. Does anyone know if you can use the .data method on ‘this’ in a plugin? Or even better if anyone know why this doesn’t work, I’d be happy to know.

Answer 1

All cases of

this.data('opened')

should be

$(this).data('opened')

Inside of the live bound event handler, this refers to the DOM node, not a jquery collection containing the dom node.
