jQuery - 查找没有事件的动态创建的元素 [英] jQuery - Find dynamically created element without events

问题描述

之前已经问过这个问题，答案是：

Tho this question has been asked before, and the answer is this:

$('#container').on('click','#dynamicElement', function(){ /* the code */ });

上面的代码将找到 #dynamicElement 当它被点击时。
但是如果没有点击，也没有任何其他事件怎么办？

The code above will find the #dynamicElement when its being clicked on. But what if there is no click, nor any other event?

假设以下情况：

$.ajax(
    url:'file.php',
    data: {'param':'value'},
    success: function(response){
         /*
         how would I get #dynamicElement if it was not click on?
         the element had no event fired at all, nor had any of its parennt
         containers.

          Now what?
         */
    }
);

推荐答案

如果你的新元素被添加到里面的页面成功回调，
此时您可以调用 $（'＃dynamicElement'）

If your new element is being added to the page inside the success callback, at that point you can call $('#dynamicElement')

使用 $（'＃dynamicElement'）回调之外的任何地方都不会返回该元素，因为它尚未添加到DOM还没有。

Using $('#dynamicElement') anywhere outside of the callback would not return the element since it had not been added to the DOM yet.
