html中鼠标点击更换背景图片的方法：
1、html代码：
<div id="menuWrapper" class="menuWrapper bg1">
<ul class="menu" id="menu">
<li class="bg1" style="background-position:0 0">
<a id="bg1" href="#">迈瑞宝</a>
<ul class="sub1" style="background-position:0 0">
<li><a href="#">报价：11.99-23.69万</a></li>
<li><a href="#">车身结构：三箱</a></li>
<li><a href="#">油耗：8.3-12.0L</a></li>
</ul>
</li>
<li class="bg1" style="background-position:-266px 0px">
<a id="bg2" href="#">索纳塔8</a>
<ul class="sub2" style="background-position:-266px 0">
<li><a href="#">报价：13.39-22.59万</a></li>
<li><a href="#">车身结构：三箱</a></li>
<li><a href="#">油耗：9.0-12.0L</a></li>
</ul>
</li>
<li class="last bg1" style="background-position:-532px 0px">
<a id="bg3" href="#">K5</a>
<ul class="sub3" style="background-position:-266px 0">
<li><a href="#">报价：10.88-25.58万</a></li>
<li><a href="#">车身结构：三箱</a></li>
<li><a href="#">油耗：8.4-13.0L</a></li>
</ul>
</li>
</ul>
</div>
2、css代码：
ul.menu >li >a{
float:left
width:265px
height:50px
margin-top:450px
text-align:center
line-height:50px
color:#ddd
background-color:#333
letter-spacing:1px
cursor:pointer
text-decoration:none
text-shadow:0px 0px 1px #fff
}
ul.menu >li ul{
list-style:none
float:left
margin-top:-180px
width:100%
height:110px
padding-top:20px
background-repeat:no-repeat
background-color:transparent
}
ul.menu >li ul li{
display:none
}
ul.menu >li ul.sub1 {
background-image: url('../img/bg1sub.png')
}
ul.menu >li ul.sub2 {
background-image: url('../img/bg2sub.png')
}
ul.menu >li ul.sub3{
background-image:url(../img/bg3sub.png)
}
ul.menu >li ul li a{
color:#fff
text-decoration:none
line-height:30px
margin-left:20px
text-shadow:1px 1px 1px #444
font-size:11px
}
ul.menu >li ul li a:hover{
border-bottom:1px dotted #fff
}
ul.menu >li ul.sub1 li{
display:block
}
3、js代码：
if (!document.defaultView || !document.defaultView.getComputedStyle) { // IE6-IE8
var oldCurCSS = jQuery.curCSS
jQuery.curCSS = function (elem, name, force) {
if (name === 'background-position') {
name = 'backgroundPosition'
}
if (name !== 'backgroundPosition' || !elem.currentStyle || elem.currentStyle[name]) {
return oldCurCSS.apply(this, arguments)
}
var style = elem.style
if (!force &&style &&style[name]) {
return style[name]
}
return oldCurCSS(elem, 'backgroundPositionX', force) + ' ' + oldCurCSS(elem, 'backgroundPositionY', force)
}
}
var oldAnim = $.fn.animate
$.fn.animate = function (prop) {
if ('background-position' in prop) {
prop.backgroundPosition = prop['background-position']
delete prop['background-position']
}
if ('backgroundPosition' in prop) {
prop.backgroundPosition = '(' + prop.backgroundPosition
}
return oldAnim.apply(this, arguments)
}
function toArray(strg) {
strg = strg.replace(/left|top/g, '0px')
strg = strg.replace(/right|bottom/g, '100%')
strg = strg.replace(/([0-9\.]+)(\s|\)|$)/g, "$1px$2")
var res = strg.match(/(-?[0-9\.]+)(px|\%|em|pt)\s(-?[0-9\.]+)(px|\%|em|pt)/)
return [parseFloat(res[1], 10), res[2], parseFloat(res[3], 10), res[4]]
}
4、实现效果
