js获取url中的查询参数

function getQueryStringArgs() {        //get query string         var qs = (location.search.length > 0 ? location.search.substring(1) : ''),            //save args obj            args = {},            //get every item            items = qs.length ? qs.split('&') : [],            item = null,            name = null,            value = null,            i = 0,            len = items.length;        for (i = 0; i < len; i++) {            item = items[i].split('=');            name = decodeURIComponent(item[0]);            value = decodeURIComponent(item[1]);            if (name.length) {                args[name] = value;            }        }        return args;    }
