How to write "if not class" jQuery selector?
提问by Youss
I want to do something with var p:
我想用 var p 做点什么：
var p = $("li:last");
But I don't want to do anything if there is a certain Class appended. I tried :not like this:
但是如果附加了某个类，我不想做任何事情。我试过：不是这样的：
var p = $("li:last:not(.Class)");
This doesn't work. How can I exclude .Class in my var?
这不起作用。如何在我的 var 中排除 .Class？

Actually :notdoes work as a selector.
实际上:not确实作为选择器工作。
If you want to select the last element that doesn't have the class, use this
如果要选择最后一个没有类的元素，请使用此
var p = $("li:not(.Class):last");
This selects first the lis that don't have that class, and thenthe last of them. See it working here.
这首先选择li没有该类的s，然后选择最后一个。看到它在这里工作。
To make it perfectly clear, these are equivalent:
为了清楚起见，这些是等效的：
var p = $("li:not(.Class):last");
var p = $("li").not(".Class").last();
And, also, these are equivalent:
而且，这些也是等价的：
var p = $("li:last:not(.Class)");
var p = $("li").last().not(".Class");

var p = $("li:last");
if (!p.hasClass('Class')){
//some stuff
}
