JS获取当前URL参数参数值

1、JS获取当前URL参数值代码：

function getUrlParam(name, win){
    win = win || window;
    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
    var r = win.location.search.substr(1).match(reg);
    if (r != null) {
        return decodeURI(r[2]);
    }
    return null;
};

2、举例：

http://localhost:8010/monitor/IndicatorScoreDeclaration.jsp?reportId=t_301071&userName=victor

var userId = getUrlParam("userName"); //结果为victor
var reportId = getUrlParam("reportId"); //结果为t_301071
