我无法让 jQuery 的 $(this)
函数按预期工作……或者更确切地说,根本无法工作。据我了解,两者都是
$('.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:选择每个 .chamber
中的前 20 个(或 19 个?).cell
,并将它们设为红色。
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?
最佳答案
首先,你是对的,两种语法是等价的。
您的压缩 jQuery 脚本似乎有问题。我从 googlecode 下载了同样的一个我在那里找不到任何 YName
变量。
我会在这里冒险说对 GetElementsByName()
的调用由于某种原因出现了乱码。尝试使用脚本的新副本。
