JQuery: How to determine if Slide event is up or down?
提问by JGreig
I have the following code:
我有以下代码:
$('a.btn-slide').toggle(function() {
$("#DivToSlide").slideUp("fast");
// ...
}, function() {
$("#DivToSlide").slideDown("fast");
// ...
});
Later in my code, I want to find out if #DivToSlideis in either the upor downposition.
在我的代码后面,我想知道#DivToSlide是在向上还是向下的位置。
How do I do that?
我怎么做?

Since the slideDownfunction hides the element after it finishes, you can simply check whether the element is visible:
由于slideDown函数在完成后隐藏元素,你可以简单地检查元素是否可见:
if ($('#DivToSlide').is(':visible'))
You could also check whether $('#DivToSlide').height()is more than some threshold.
您还可以检查是否$('#DivToSlide').height()超过某个阈值。

if($(this).next('.nxt_div').height()>1){ }
