I already am using Firebug. I'm just learning JQ and was trying to
save some time. resizeable.js works fine when summoned from the demo
html, but for me, the same call to .resizeable() with the same nil
arguments results in the errors I mentioned
Again, the error is below (generated by Firefox)
this.element.position is not a function
[Break on this error] var o = this.options, iniPos =
this.element.position(), el = this.element,
and here's the snippet from resizeable.js...
start: function(e) {
304 var o = this.options, iniPos = this.element.position(), el =
this.element,
305 num = function(v) { return parseInt(v, 10) || 0; }, ie6 =
$.browser.msie && $.browser.version < 7;
306 o.resizing = true;
307 o.documentScroll = { top: $(document).scrollTop(), left: $
(document).scrollLeft() };
308
In line 304 "this.element" is valid but the error is saying
element.position() is undefined. Why? I don't know. I'm just typing
$(foo).draggable(); and don't really need to know how it's all working
underneath. If I did, I'd go back to wrting my own framework again.
Well, that's not entirely true, but you know what I mean.
