jQuery slideToggle调用一次 [英] jquery slideToggle call once

问题描述

那可能很简单，但是大约是凌晨2点，而且很困:)

That just could be very simple, but it's about 2AM and getting quite sleepy :)

我有一个简短的脚本，该脚本可以使"slideToggle" div不显示.

I have short script which "slideToggle" div from being non-displayed.

$('#cmnt_add').click(function () { $('.dark_div_add').slideToggle(1100); });

是否有机会进行一次锻炼，所以如果打开未显示的DIV，单击相同的链接将无济于事?

Is there a chance to make it workout once, so if non-displayed DIV is opened, clicking same link won't do a thing?

提前谢谢！

推荐答案

使用.one():

$('#cmnt_add').one("click", function () { $('.dark_div_add').slideToggle(1100); });

来自 jQuery的文档:

将处理程序附加到元素的事件.处理程序被执行 每个元素最多一次.

Attach a handler to an event for the elements. The handler is executed at most once per element.

此外，如果您知道它最初会被隐藏，那么使用.slideDown()而不是.slideToggle()可能是个好主意...

Also, if you know it'll be hidden initially, using .slideDown() instead of .slideToggle() may be a good idea...
