使用Javascript MutationObserver:

// Select the target node.
var target = document.querySelector('mydiv')

// Create an observer instance.
var observer = new MutationObserver(function(mutations) {
    console.log(target.innerText);   
});

// Pass in the target node, as well as the observer options.
observer.observe(target, {
    attributes:    true,
    childList:     true,
    characterData: true
});

详情请参阅MDN文档;这应该适用于几乎所有当前的浏览器，包括IE11。

下面的代码为我工作:

$("body").on('DOMSubtreeModified', "mydiv", function() {
    alert('changed');
});

Adding some content to a div, whether through jQuery or via de DOM-API directly, defaults to the .appendChild() function. What you can do is to override the .appendChild() function of the current object and implement an observer in it. Now having overridden our .appendChild() function, we need to borrow that function from an other object to be able to append the content. Therefor we call the .appendChild() of an other div to finally append the content. Ofcourse, this counts also for the .removeChild().

var obj = document.getElementById("mydiv");
    obj.appendChild = function(node) {
        alert("changed!");

        // call the .appendChild() function of some other div
        // and pass the current (this) to let the function affect it.
        document.createElement("div").appendChild.call(this, node);
        }
    };

在这里您可以找到一个naïf示例。我想你们可以自己扩展。 http://jsfiddle.net/RKLmA/31/

顺便说一下:这表明JavaScript遵循openclose原则。：）

你可以试试这个

$('.myDiv').bind('DOMNodeInserted DOMNodeRemoved', function() {

});

但这在ie浏览器中可能行不通，我还没测试过

如果你不想使用定时器和检查innerHTML，你可以尝试这个事件

$('mydiv').on('DOMSubtreeModified', function(){
  console.log('changed');
});

更多细节和浏览器支持数据在这里。

您可以将div的旧innerHTML存储在一个变量中。设置检查旧内容与当前内容是否匹配的时间间隔。如果这不是真的，那就做点什么。
