jQuery .live加载事件 [英] jquery .live on load event

问题描述

我需要一种方法来使用jquery .live()函数对通过ajax加载的元素进行操作.

I need a way to use the jquery .live() function to act on elements that are loaded via ajax.

例如，通过ajax .load()

For instance a div is loaded via ajax .load()

<div id="mydiv"></div>

通常我对click事件执行.live()，但是我需要知道如何告诉dom这个新的div已加载，而没有来自用户的任何明确动作/事件.

Normally I do .live() with a click event, but I need to know how to tell the dom that this new div has loaded without any explicit actions/events from the user.

此代码无效，但我想执行以下操作:

This code doesn't work, but I want to do something like this:

mydiv = $("#mydiv");

mydiv.live("mydiv.length > 0", function() {
       // do something
});

"mydiv.length"是典型"click"或其他事件的替代物.

The "mydiv.length" being a substitue for the typical "click" or other event.

推荐答案

没有"DOM更改"事件，在浏览器上创建事件很费力.最好使用load方法的回调来触发所需的功能.

There isn't a "DOM changed" event and creating one is taxing on the browser. You are best off using the callback for the load method to trigger the functions you need to.

$('#foobar').load('myurl.html',function() {
    var mydiv = $("#mydiv");
});
