html如何实现换肤功能,第1张

你可以先写几个css文件,这些文件是皮肤样式表。然后写个JS文件,写几个函数,分别给hf函数换肤参数。给个示例。

function hf(type)

{

if (type == "orange") {

document.getElementById("background").href = "orange.css"

}

else if (type == "green") {

document.getElementById("background").href = "green.css"

}

else if (type == "gray") {

document.getElementById("background").href = "gray.css"

}

}

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]]

}
