jQuery $(this).find()和$(selector,this)不起作用

jQuery $(this).find() and $(selector,this) not working

我有麻烦让jQuery的$(this)函数工作如预期…或者更确切地说，工作。在我看来，

$('.chamber').each(function(){
    $(this).find('.cell').slice(0,19).css('background-color','red');
});

和

$('.chamber').each(function(){
    $('.cell',this).slice(0,19).css('background-color','red');
});

应该做同样的事情:选择前20(或19?)每个.chamber中的.cell s，并使它们变为红色。

不幸的是，实际发生的是它们都抛出相同的错误:

Uncaught exception: ReferenceError: Undefined variable: YName

我做错了什么?

首先，你是对的，两种语法是等价的。

你的迷你jQuery脚本似乎有问题。我从googlecode下载了相同的一个，我在那里找不到任何YName变量。

我在这里冒昧地说，由于某种原因，对GetElementsByName()的呼叫被打乱了。尝试使用脚本的新副本。

看这个例子:它工作得很好http://jsfiddle.net/FCFmy/
