如何从JQuery对象获取javascript控件？

Question

I'm a beginner in JQuery,

How can I get the control as a javascript object from a JQuery object

var _object = $(this). ??

Answer 1

Most common var _object = $(this)[0];

If you have more than 1 elements matched: $(this)[0] , $(this)[1] , $(this)[2] and so on.

$(this).get() is also possible. It's only advantage over the array model is that it allows selection of the kind $(this).get(-1) where it gets you the last matched object

Answer 2

(function (e) {
    var a = false;
    try {
        $(this)[0];
        a = true;
    } catch (h) {}
    alert(a.toString());
})(window);

Answer 3

var _object = $(this)[0];

我认为这是对的，不能检查，因为我在我的手机上。

Answer 4

In your case, simply use this .

$(this)[0] == this if this is a DOM element. If it's something else, eg a selector, $(this)[0] is the way to go.
