JS获取URL后面的参数

    var url = location.search;

    url = decodeURI(url);

    var theRequest = new Object();

    if (url.indexOf("?") != -1) {

        var str = url.substr(1);

        strs = str.split("&");

        for(var i = 0; i < strs.length; i ++) {

            theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);

        }

    }

    //url后传递的参数

    var id = theRequest.id;
