jQuery UI Widgets - storing jQuery objects in instance variables

jQuery's wrap method clones the element. The following uses a cloned version of the container element:

$(this.element).wrap(this.container) //
`this.container` is cloned first

When you try to apply the styles after the fact, those styles are applied to the non-cloned version that wasn't attached to the DOM.

You can fix this by adding the styles prior to wrapping the element:

container.css({"position": "relative",
"overflow": "hidden", "backgroundColor": "#CCC"});

Also note that calling remove doesn't remove anything because only the cloned container was attached to the DOM. Instead clean it up by setting it to null.

container = null;

Here is a JSFiddle:

How to simplify jquery code with variables?
Take advantage of the fact that you can add information to your markup that guides behaviors supplied by your JavaScript code. Assuming your toggle controls are buttons: <button class=toggle-layer data-target=FloatingLayer1>Layer 1</button> <button class=toggle-layer data-target=FloatingLayer2>Layer 2</button> <button class=toggle-layer data-target=FloatingLayer3>Lay

"this" in JavaScript objects vs. jQuery $(this)
Short answer: do $('.personName').mouseover(function(event) { obj.highlight($('faceIndex')); }); Longer explanation: Javascript doesn't really have a concept of this. At least not in the way you're used to thinking of it. Oh there's a keyword alright, and it kind of does the thing you expect a lot of the times but it doesn't work the way that you probably thi
