在style里面设置一个background-image:url(test.css)

CSS中URL与Class的运用示例

.addForm_titleName_pic{
    background-image:url(images/write.gif);
}

<td class=class1>
相当于<td style="background-image:url(test.css)">

以后注意相关方面的灵活运用
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <link rel="stylesheet" href="03.css"> <script type="text/javascript" src="03.js"></script> </head> <body> <div class="adv"></div> <div class="btn" id="btn01">按钮1</div> <div class="btn" id="btn02">按钮2</div> <div class="btn" id="btn03">按钮3</div> <div class="btn"></div> <div class="adv-con"></div> <div class="con" id="con01">内容1</div> <div class="con" id="con01">内容2</div> <div class="con" id="con01">内容3</div> </body> </html>window.onload=test; function test(){ var btns=document.getElementsByClassName("btn"); var btns=document.getElementsByClassName("con"); btns{0}.onclick=function(){ cons[01].style.display="black" cons[02].style.display="none" cons[03].style.display="none" } btns{1}.onclick=function(){ cons[02].style.display="black" cons[01].style.display="none" cons[03].style.display="none" } btns{2}.onclick=function(){ cons[03].style.display="black" cons[02].style.display="none" cons[01].style.display="none" } } margin:0px; padding: 0px; adv{ width: 300px; height: 550; background-color: aqua; } .adv=btn{ width: 300px; height:50px; background-color: black; } .adv=btn{ width: 300px; height:300px; background-color: aquamarine; } .btn{ width:100px; height:50px; float:left; line-height:50px; text-align: center; cursor: pointer; } #btn01{ background-color: blue; } #btn02{ background-image:yellow; } #btn03{ background-image: green; } .con{ width: 300; height 300px; } #con01{ background-color: azure; } #con02{ background-color: brown; } #con03{ background-color: brown; display: none; } 修改代码
