js 获取URL参数

Date.prototype.format = function (format) {
    var o = {
        "M+": this.getMonth() + 1, //month
        "d+": this.getDate(),    //day
        "H+": this.getHours(),   //hour
        "m+": this.getMinutes(), //minute
        "s+": this.getSeconds(), //second
        "q+": Math.floor((this.getMonth() + 3) / 3),  //quarter
        "S": this.getMilliseconds() //millisecond
    }
    if (/(y+)/.test(format)) format = format.replace(RegExp.$1,
    (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o) if (new RegExp("(" + k + ")").test(format))
        format = format.replace(RegExp.$1,
      RegExp.$1.length == 1 ? o[k] :
        ("00" + o[k]).substr(("" + o[k]).length));
    return format;
}

//时间格式化
function GetFormatDate(d, f) {
    var date = new Date(d);
    return date.format(f);
}


//获取当前url参数值
function getUrlParameterAdv(asName, lsURL) {
    loU = lsURL.split("?");
    if (loU.length > 1) {
        var loallPm = loU[1].split("&");
        for (var i = 0; i < loallPm.length; i++) {
            var loPm = loallPm[i].split("=");
            if (loPm[0] == asName) {
                if (loPm.length > 1) {
                    return loPm[1];
                } else {
                    return "";
                }
            }
