Browser 行为,有巨大的武器
原标题:Browser behavior with huge doms

谁能说不同的浏览器如何操作:

照片是一份超文本文件,基本上使静态仪器的内容与许多数据相容。

<div class="abundant_class">
    <div class="abundant_class">
        <div class="abundant_class"></div>
        <div class="abundant_class"></div>
        ...
    </div>       
    <div class="abundant_class">...</div>
    <div class="abundant_class">...</div>
    ...
</div>

Imagine O(1000)这种内容载于该文件。

向所有这些要素分配点击事件的最快途径是什么?

  • <div class="abundant_class" onclick="javascript:foo()">
  • $( .abundant_class ).click(function(foo();));
  • $( div ).click(function(){if ($(this).hasClass( abundant_class )){foo();}
  • something else?

我特别想知道,这些选择会产生多少记忆和万国邮联。

提前感谢。
