网站换肤,之前感觉总是很神奇啊,今天就来总结一下。我写的就是两种思路。

首先都需要建一个css文件夹,里面存放不同颜色的css文件:blue.css; red.css; yellow.css; green.css 在这几个文件中分别写好要改变的样式。

接下来就是html文件,首先第一种思路:只写一个link标签(不推荐,原因请继续阅读)。代码如下:

<!--index.html-->
<head> 
<meta charset="UTF-8">
<title>动态换肤</title>
<link rel="stylesheet" type="text/css" href="css/blue.css">
<style>
*{ margin: 0; padding: 0; }
div{
    height: 50px; 
    background-color: black; 
    padding-left: 10px;
}
div section{
    width: 30px; 
    height: 30px; 
    margin: 10px; 
    display: inline-block; 
}
div section:nth-of-type(1){
    background-color: red; 
}
div section:nth-of-type(2){
    background-color: blue; 
}
div section:nth-of-type(3){
    background-color: green; 
}
div section:nth-child(4){
    background-color: yellow; 
}
</style>
</head>
<body>
<div>
<section data-color="red"></section>
<section data-color="blue"></section>
<section data-color="green"></section>
<section data-color="yellow"></section>
</div>
<script>
var div = document.getElementsByTagName("div")[0];
//添加鼠标单击事件
div.onclick = function(event){
console.log(event.target);
var ele = event.target;
console.log(ele.tagName);//使用.tagName时,控制台输出全部大写,所以在下面的if判断中,使用“SECTION”.
if(ele.tagName == &#39;SECTION&#39;){
var color = ele.dataset.color;
//var color = ele.getAttribute("data-color");
var link = document.createElement("link");
link.href = &#39;css/&#39; + color + ".css";
link.rel = "stylesheet";
// 添加样式表到head,但是会造成页面样式表越来越多,所以不推荐
document.head.appendChild(link); 
}
}
</script>
</body>

第一种思路是只写一个link,然后不断添加样式表到head,但是会造成页面样式表越来越多,所以不推荐。

第二种思路:写4个link标签,然后通过调节link的可用与否来实现网站换肤。代码如下:

<head>
<meta charset="UTF-8">
<title>动态换肤</title>
<link rel="stylesheet" type="text/css" href="css/blue.css">
<link rel="stylesheet" type="text/css" href="css/red.css">
<link rel="stylesheet" type="text/css" href="css/green.css">
<link rel="stylesheet" type="text/css" href="css/yellow.css">
<style>
*{ margin: 0; padding: 0; }
div{ 
    height: 50px; 
    background-color: black;
    padding-left: 10px; 
}
div section{ 
    width: 30px; 
    height: 30px; 
    margin: 10px; 
    display: inline-block; 
}
div section:nth-of-type(1){ 
    background-color: blue; 
}
div section:nth-of-type(2){ 
    background-color: red; 
}
div section:nth-of-type(3){ 
    background-color: green; 
}
div section:nth-child(4){ 
    background-color: yellow; 
}
</style>
</head>
<body>
<div>
<section data-color="0"></section>
<section data-color="1"></section>
<section data-color="2"></section>
<section data-color="3"></section>
</div>
<script>
var links = document.getElementsByTagName(&#39;link&#39;);
function enableLinks(index){
for(var i = 0;i < links.length; i++){//循环查找4个link标签
//disabled表示关闭,如果i不等于当前index,则disabled就是true,即关闭该link标签
//.sheet表示样式表
links[i].sheet.disabled = i!=index;
}
}
enableLinks(2);
//给div标签添加鼠标点击事件
//event:事件对象
document.querySelector(&#39;div&#39;).onclick = function(event){
var index = event.target.dataset.color;
console.log(index);
if(index == undefined){
return;
}else{
//调用enableLinks()
enableLinks(index);
}
}
</script>
</body>
Copy after login

注意两种方法的html部分section的自定义属性data-color,一个是颜色,一个是数字。
