将jQuery元素数组转换为jQuery包装的元素集

问题描述：

是否有任何将[$(div), $(span), $(li)]转换为$(div, span, li)的优雅方法?

Is there any elegant way of turning [$(div), $(span), $(li)] into $(div, span, li)?

我需要的是一组由jQuery包装的元素，而不是一组jQuery元素.我想用尽可能少的代码行做到这一点，并且循环最少(如果有的话).

What I need is a jQuery-wrapped set of elements instead of an array of jQuery elements. I would like to do this in as few lines of code as possible, and with minimal (if any) looping.

编辑:对于那些对此问题感到困惑的人，可以使用console.log在已已选择的元素数组上从firebug复制并粘贴此代码.

For those of you confused by this question, this code is copied and pasted from firebug using console.log on an array of elements that have already been selected.

答

jQuery的map()函数非常适合重塑数组和/或jQuery集合.

jQuery's map() function is perfect for reshaping arrays and/or jQuery collections.

因此，给出了一个像这样的数组集:

So, given an array set like so:

var arrayOfJQ_Objects = [$("div"), $("span"), $("li")];

只需一行代码(在jsFiddle上查看它):

This one line of code is all you need (See it in action at jsFiddle):

$(arrayOfJQ_Objects).map (function () {return this.toArray(); } );

此控制台在Firebug中显示:

Resulting in this console display in Firebug:

jQuery(div, span, li)

同样， jQuery的.toArray()函数.

Reference, also, jQuery's .toArray() function.
