$(this) breaks chainability when this is a jQuery object

[dlikhten]

When chaining and using a custom function that uses and returns $(this) the $(this) call will break the chainability as it will not transfer the pre-destructive states.

Is this behavior valid, and my use case is an invalid use of jQuery extensions or should this behavior be supported?

$(this) is a new jQuery object, with no previous states.

The "stack of states" goes with a specific object. You simply need to keep a reference to the original jQuery object.

Why do you pass a jQuery object to jQuery ? simply use 'this'. If you want to save a jQuery object to a var, you simply assing 'this' not $(this).

If you really have a justified reason, you can do:

var $copy = $(this);
$copy.prevObject = this.prevObject;

I'll let you provide a valid use for this before closing. Let me know if I can simply close this.
