jquery event handler: div becomes visible/hidden

提问by frenchie

I have a div and I'd like to have an event handler listen to when it becomes visible and hidden. How do you do that?

我有一个 div，我想让一个事件处理程序在它变得可见和隐藏时监听。你是怎样做的？

You can use the callback parameter in the show()and hide()methods like this:

您可以在show()和hide()方法中使用回调参数，如下所示：

$('#myDiv').show(0, onDivShow);
$('#myDiv').hide(0, onDivHide);

function onDivShow() { //your code here }
function onDivHide() { //your code here }

See a working example here: http://jsfiddle.net/N7UNU/

You can create a trigger. You would, of course, have to fire the trigger, but that is one way to do it.

您可以创建触发器。当然，您必须触发触发器，但这是一种方法。
