jQuery $(this).find()和$(selector,this)不起作用 [英] jQuery $(this).find() and $(selector,this) not working
问题描述
我无法让jQuery的 $(this)
函数按预期工作......或者更确切地说,可以工作。据我所知,两个
I'm having trouble getting jQuery's $(this)
function to work as expected... or rather, to work at all. As I understand it, both
$('.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?) .cell
在每个 .chamber
中,并将它们设为红色。
should do the same thing: select the first 20 (or 19?) .cell
s in each .chamber
, and make them red.
不幸的是,实际发生的是它们都抛出相同的错误:
Unfortunately, what actually happens is they both throw the same error:
Uncaught exception: ReferenceError: Undefined variable: YName

我做错了什么?
推荐答案
首先,你是对的,两种语法都是等价的。
First, you're correct, both syntaxes are equivalent.
你的缩小jQuery脚本似乎有问题。我从 googlecode ,我在那里找不到任何 YName
变量。
There seems to be a problem with your minified jQuery script. I downloaded the same one from googlecode and I cannot find any YName
variable in there.
我会在这里出去玩说出于某种原因,对 GetElementsByName()
的调用已经出现乱码。尝试使用该脚本的新副本。
I'll go out on a limb here and say calls to GetElementsByName()
have been garbled for some reason. Try using a fresh copy of the script.
