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); } alert (getRootPath()); </script>
