Was trying to add some jQueryUI code to my site and can't get it to actually use the effect I want. Instead I see a bunch of errors in firefox saying

Error: jQuery.easing[this.options.easing || (jQuery.easing.swing ? "swing" : "linear")] is not a function
Source File: modules/jquery_update/replace/jquery.min.js
Line: 32

This is the code that triggers the error:

$(document).ready(function() {
  function runEffect(){
    var options = { mode: "hide", direction: "right" };
    //run the effect
  $("#map_toggle").click(function() {
    return false;

Only thing I could find searching around is vague references to a jquery plugin called Easing, but I can't find anything about adding it to drupal, or if that's even the solution.


Simplifying the code a little I came up with the following:

$(document).ready(function() {
var options = {};
$("#map_toggle").click(function() {
return false;

This code still doesn't work, but it's cleaner than the first post and maybe easier to read.

I found that replacing the toggle line with


this actually functions the way I intended.

Although this solves the issue for now, I'm curious to know why the examples on the jqueryUI page (where I got this snippet) don't work.
It seems that only the jquery effects are working, and none of the jqueryUI effects

What version of jQuery UI are you trying to install? Is it compatible with jQuery 1.2.6 or does it require 1.3.x?

Status:Postponed (maintainer needs more info)» Closed (fixed)

Closing due to lack of activity.

Version:6.x-1.1» 6.x-2.0-alpha1

Same error using 6.x-2.0-alpha1 and hierarchical select 3.3

@FiNeX is hierarchical select 3.3 compatible with jQuery 1.3.2? If not, there need to be an issue filed with that module or it is incompatible with jQuery Update 2.x.

Status:Active» Closed (fixed)

I'm sorry, I've wrongly installed jquery.ui module. I've set this bug back to "closed". Sorry again.
