jQuery - 从DOM中删除元素时触发事件 [英] jQuery - Trigger event when an element is removed from the DOM

问题描述

我正试图找出如何从页面中删除某个元素时执行某些js代码：

I'm trying to figure out how to execute some js code when an element is removed from the page:

jQuery('#some-element').remove(); // remove some element from the page
/* need to figure out how to independently detect the above happened */

是否有为此而定制的活动，例如：

is there an event tailored for that, something like:

jQuery('#some-element').onremoval( function() {
    // do post-mortem stuff here
});

谢谢。

推荐答案

刚刚检查，它已经内置在当前版本的JQuery中：

Just checked, it is already built-in in current version of JQuery:

jQuery - v1.9.1

jQuery - v1.9.1

jQuery UI - v1.10.2

jQuery UI - v1.10.2

$("#myDiv").on("remove", function () {
    alert("Element was removed");
})

重要：这是Jquery UI 脚本（而不是JQuery）的功能，因此您必须加载脚本（jquery和jquery-ui）以使其正常工作。以下是示例： http://jsfiddle.net/72RTz/

Important: This is functionality of Jquery UI script (not JQuery), so you have to load both scripts (jquery and jquery-ui) to make it work. Here is example: http://jsfiddle.net/72RTz/
