在链接的鼠标悬停上更改div的背景图像

Question

我想要实现的目标

我希望div的背景图像在所述div内的链接的鼠标悬停上改变.

例

<div id="container">
     <a href="" id="linktomouseover"></a>
</div>

我试过的

我尝试使用jQuery交换背景图像:

<script language="javascript" type="text/javascript">

jQuery('#linktomouseover').mouseover(function()
{
jQuery('#container').css("background-image", "url(bg-b.png)");
});

</script>

任何人都可以告诉我我缺少的东西吗？

解

<style> 
#container{ 
width:100%; 
height:100%; 
background-image:url(http://thumbs.dreamstime.com/thumblarge_536/12838649102C1cO5.jpg); 
} 
</style> 

<div id="container"><br><br> 
<a href="" id="linktomouseover">hover</a> 
</div>

<script> 
jQuery('#linktomouseover').hover(function() 
{ 
jQuery('#container').css("background-image", 
"url(http://static4.depositphotos.com/1011237/285/i/450/dep_2853473-Background-for-your-web-store.jpg)
"); 
}).mouseleave(function(){
jQuery('#container').css("background-image", "url(http://thumbs.dreamstime.com/thumblarge_536/12838649102C1cO5.jpg)"); 
});
</script>
