复制代码 代码如下:

<script>

function getRootPath(){

var strFullPath=window.document.location.href;

var strPath=window.document.location.pathname;

var pos=strFullPath.indexOf(strPath);

var prePath=strFullPath.substring(0,pos);

var postPath=strPath.substring(0,strPath.substr(1).indexOf(‘/')+1);

return(prePath+postPath);

}

var webpath=getRootPath(); //webpath就是目录路径变量

</script>
