获取url后面的路径

function GetUrlRelativePath()

{

var url = document.location.toString();

var arrUrl = url.split("//");

var start = arrUrl[1].indexOf("/");

var relUrl = arrUrl[1].substring(start);//stop省略，截取从start开始到结尾的所有字符

if(relUrl.indexOf("?") != -1){

relUrl = relUrl.split("?")[0];

}

return relUrl;

}

或者

function GetUrlRelativePath(url)

{

var arrUrl = url.split("//");

var start = arrUrl[1].indexOf("/");

var relUrl = arrUrl[1].substring(start);//stop省略，截取从start开始到结尾的所有字符

if(relUrl.indexOf("?") != -1){

relUrl = relUrl.split("?")[0];

}

return relUrl;

}
