如何使用Javascript更改附加的CSS文件? [英] How can you change the attached CSS file with Javascript?

问题描述

我想知道，是否可以使用JavaScript更改附件样式表?

例如:

 < link href ="stylesheet.css" rel ="stylesheet" type ="text/css">.....< div id ="controls">< div id ="red" onClick ="styler(1)"> R</div>< div id ="green" onClick ="styler(2)"> G</div>< div id ="blue" onClick ="styler(3)"> B</div>< div id ="reset" onClick ="styler(4)">重置</div></div> 

JavaScript

 函数样式器(attr){开关(attr){case'1':document .----- ="stylesheet1.css"; break;case'2':document .----- ="stylesheet2.css"; break;case'3':document .----- ="stylesheet3.css"; break;case'4':document .----- ="stylesheet.css"; break;默认值:; break;}} 

解决方案

向链接标记添加ID并使用

 < link id ="myStyleSheet" href ="stylesheet.css" rel ="stylesheet" type ="text/css"/>< script type ="text/javascript">函数样式器(attr){var href;开关(attr){case'1':href ="stylesheet1.css"; break;case'2':href ="stylesheet2.css"; break;case'3':href ="stylesheet3.css"; break;case'4':href ="stylesheet.css"; break;默认值:; break;}document.getElementById('myStyleSheet').href = href;}</script>

I was wondering, is it possible to change the attached stylesheet using JavaScript?

For example:

<link href="stylesheet.css" rel="stylesheet" type="text/css">
.....
<div id="controls">
    <div id="red" onClick="styler(1)">R</div>
    <div id="green" onClick="styler(2)">G</div>
    <div id="blue" onClick="styler(3)">B</div>
    <div id="reset" onClick="styler(4)">Reset</div>
</div>

JavaScript

function styler(attr){
    switch(attr){
         case'1':document.----- = "stylesheet1.css";break;
         case'2':document.----- = "stylesheet2.css";break;
         case'3':document.----- = "stylesheet3.css";break;
         case'4':document.----- = "stylesheet.css";break;
         default:;break;
     }
}

解决方案

Add an id to the link tag and use

<link id="myStyleSheet" href="stylesheet.css" rel="stylesheet" type="text/css" />

<script type="text/javascript">
    function styler(attr){
        var href;
        switch(attr){
            case'1':href = "stylesheet1.css";break;
            case'2':href = "stylesheet2.css";break;
            case'3':href = "stylesheet3.css";break;
            case'4':href = "stylesheet.css";break;
            default:;break;
        }
        document.getElementById('myStyleSheet').href = href;
    }
</script>
