Date的格式化扩展：

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

//使用：
var now = new Date().Format("yyyy-MM-dd");

获取URL中值：

//获取URL中值
function getQueryString(name) {
    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
    var r = window.location.search.substr(1).match(reg);
    if (r != null) return unescape(r[2]); return null;
}
