Manipulating jQuery object without changing the html element

Question

I have a variable with a jQuery object, for example:

var div = $('#div_element');

How can I manipulate ONLY the div variable, without changing the #div_element itself?

---

I want to do some edits on the div variable and to pass it as an argument to a plugin, like this:

var el = $('#div');
el.find(':first').remove();
$().popup(el); //I wrote this plugin myself

Actually I want to display popup containing the #div element (with removed the first "child"), but don't want to change the #div element itself.

Answer 1

使用clone创建该元素的副本。

var el = $('#div').clone();

Answer 2

您可以使用像

$().popup($("#div :not(:first-child)"));
