如何只选择未使用jQuery隐藏的列表项?

A really simple question I'm sure but...

一个很简单的问题，但是…

I have an unordered list, in which some amount of the list items have been slid up. I want to extract information from spans within the visible list items only, using an $.each loop.

我有一个无序列表，其中一些列表项已经滑了上来。我想只使用$，从可见列表项中提取信息。每一个循环。

I want to write something along these lines to access this information but I don't know what the right parameter is:

我想沿着这些线写一些东西来获取这些信息，但是我不知道正确的参数是什么:

$("li.class").each(function(){
  if ("li.class" *isn't hidden*) { 
    // get information from span
  }
})

The best I can come up with is adding a class each time a list item is slid up and then removing that class when it slides back down, which I guess would be fine, but I'm suspecting jQuery already has something in place.

我所能想到的最好的方法是每次拖拽一个列表项时都添加一个类，然后在返回时删除这个类，我想这是可以的，但是我怀疑jQuery已经有了一些东西。

Thanks!

谢谢!

Something like this:

是这样的:

    $(function() {
        $('li.class:visible').each(function() {

        });
    });

You can use the :visible pseudo selector:

您可以使用:可见伪选择器:

$("li.class:visible").each(function() {
    // get information from span, like ...
    $("span", this).text();
})
