JS版網站風格切換執行個體代碼

樣式表串連,設3種風格，把你要改變的圖片背景等寫入樣式表。 複製代碼 代碼如下:<link media="screen" href="/css/default.css" rel="stylesheet" type="text/css" title="default" />
<link media="screen" href="/css/blue.css" rel="alternate stylesheet" type="text/css" title="blue" />
<link media="screen" href="/css/orange.css" rel="alternate stylesheet" type="text/css" title="orange" />

第一個是預設樣式表。

function getCookie(Name) {
var re=new RegExp(Name+"=[^;]+", "i"); //construct RE to search for target name/value pair
if (document.cookie.match(re)) //if cookie found
return document.cookie.match(re)[0].split("=")[1] //return its value
return null
}
function setCookie(name, value, days) {
var expireDate = new Date()
//set "expstring" to either future or past date, to set or delete cookie, respectively
var expstring=(typeof days!="undefined")? expireDate.setDate(expireDate.getDate()+parseInt(days)) : expireDate.setDate(expireDate.getDate()-5)
document.cookie = name+"="+value+"; expires="+expireDate.toGMTString()+"; path=/";
}
function deleteCookie(name){
setCookie(name, "moot")
}
function setStylesheet(title) {
var i, cacheobj
for(i=0; (cacheobj=document.getElementsByTagName("link")[i]); i++) {
if(cacheobj.getAttribute("rel").indexOf("style") != -1 && cacheobj.getAttribute("title")) {
cacheobj.disabled = true
if(cacheobj.getAttribute("title") == title)
cacheobj.disabled = false //enable chosen style sheet
}
}
}
function chooseStyle(styletitle, days){
if (document.getElementById){
setStylesheet(styletitle)
setCookie("mysheet", styletitle, days)
}
}
var selectedtitle=getCookie("mysheet")
if (document.getElementById && selectedtitle!=null) //load user chosen style sheet if there is one stored
setStylesheet(selectedtitle)

調用方法 複製代碼 代碼如下:<a title="預設風格" href="javascript:chooseStyle('default',5)">預設風格</a>
<a title="橙色風格" href="javascript:chooseStyle('orange',5)">橙色風格</a>
<a title="藍色風格" href="javascript:chooseStyle('blue',5)">藍色風格</a>

注意：title內容改成你樣式表的名字，我這裡是設定為5天。
