聆听DIV中的更改并采取相应措施 [英] Listen to changes within a DIV and act accordingly

问题描述

我有一个获取XML文档并根据XSL文档对其进行转换的函数.然后将结果放入ID为laneconfigdisplay的div中.我想做的是，独立于转换逻辑，为该div设置一个jQuery change事件，以便我可以知道它何时已更改，并运行一些jQuery代码.

I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay. What I want to do is, separate to the transformation logic, setup a jQuery change event for that div so I can tell when it has changed, and run some jQuery code.

我尝试了以下方法，但是不起作用！

I have tried the following, but it does not work!

$(document).ready(function()
{
    $('#laneconfigdisplay').change(function() {
        alert('woo');
    });
    //Do XML / XSL transformation here
});

<!-- HTML code here -->
<div id="laneconfigdisplay"></div>

我在做什么错了?

推荐答案

您可以选择创建自己的自定义事件，以使逻辑仍然清晰分开.

You can opt to create your own custom events so you'll still have a clear separation of logic.

绑定到自定义事件:

$('#laneconfigdisplay').bind('contentchanged', function() {
  // do something after the div content has changed
  alert('woo');
});

在更新div的函数中:

In your function that updates the div:

// all logic for grabbing xml and updating the div here ..
// and then send a message/event that we have updated the div
$('#laneconfigdisplay').trigger('contentchanged'); // this will call the function above
