如何将jQuery对象添加到jQuery复合对象

Simply put: the jQuery object is a composite pattern. How do I add jQuery objects to it?

简单地说:jQuery对象是一个复合模式。如何添加jQuery对象?

An example:

var e1 = $('#element1');
var e2 = $('#element2');

...

I know want to create a new jQuery object jq such that it is composed of e1 and e2. I want to be able to do something like the following:

我知道想创建一个新的jQuery对象jq,它由e1和e2组成。我希望能够做类似以下的事情:

var jq = $();
jq.addInjQueryObjects([e1, e2]);
jq.hide();

how do I do this?

我该怎么做呢?

By the way, I realize that I could have just selected #element1 AND #element2 to begin with, that's not what I'm talking about.

顺便说一句,我意识到我可以选择#element1 AND#element2开始,这不是我所说的。

You can use jQuery's .add() method:

你可以使用jQuery的.add()方法:

var e1 = $('#element1');
var e2 = $('#element2');

var jq = $();
jq = jq.add(e1).add(e2);
jq.hide();

It returns a new jQuery object instead of modifying the original, so you need to overwrite the original if you want to reuse the same variable.

它返回一个新的jQuery对象而不是修改原始对象,因此如果要重用同一个变量,则需要覆盖原始对象。

EDIT: Note that you can also use jQuery.merge(), which will modify the original, but you'll need to pass in an Array of the DOM elements instead of the jQuery objects.

编辑:请注意,您也可以使用jQuery.merge(),它将修改原始,但您需要传入DOM元素的数组而不是jQuery对象。

var e1 = $('#element1');
var e2 = $('#element2');

var jq = $();
$.merge( jq, [e1[0], e2[0]] );
jq.hide();
