jquery hover mouse out

jqueryhover

提问by Stuart Robson

I want a simple slide down / up animation on a mouse over of a link. I can get the mouse over to work but I can't work out how to get the mouseout to do it's thing.

我想要一个简单的在鼠标悬停在链接上的向下/向上滑动动画。我可以让鼠标移过去工作,但我不知道如何让鼠标移开来做这件事。

Here's what I have for the hover effect:

这是我对悬停效果的看法:

<script type="text/javascript" src="http://www.google.com/jsapi"></script>

<script type="text/javascript">

google.load("jquery", "1.3.2"); //load version 1.3.2 of jQuery

google.setOnLoadCallback(function() {
    jQuery(
        function($) {
            $("a.button").hover(function(){$(this).animate({"marginTop": "0px"}, "fast")   

        });
    });
});
</script>

How do I get this to move the margin up 16px when mouse out?

如何在鼠标移开时将边距向上移动 16px?

回答by Philippe Leybaert

The hover event in jQuery needs 2 callback functions: one when the pointer moves over the item, and one when it leaves:

jQuery 中的悬停事件需要 2 个回调函数:一个是当指针移动到项目上时,一个是在它离开时:

$(item).hover(function() { ... }, function() { ... });

In your case:

在你的情况下:

$("a.button").hover(
   function() {
      $(this).animate({"marginTop": "0px"}, "fast");
   },
   function() {
      $(this).animate({"marginTop": "16px"}, "fast");
   }
);

In newer versions of jQuery (>=1.7) you can also take this approach:

在较新版本的 jQuery (>=1.7) 中,您也可以采用这种方法:

$("a.button").on('mouseenter',function(){
  $(this).animate({"marginTop": "0px"}, "fast");
});
$("a.button").on('mouseleave',function(){
  $(this).animate({"marginTop": "16px"}, "fast");
});

In my opinion this is a cleaner approach, and it also takes advantage of the the new .on() function (documentation here)

在我看来,这是一种更简洁的方法,并且还利用了新的 .on() 函数(此处为文档

Simpler solution:

更简单的解决方案:

$("a.button").hover(function() {
  $("a.button").css("cursor","pointer");
});
