}

var current_time = "2007-2-2 7:30";
var stop_time = "2007-1-31 8:30";
alert(CompareDate(current_time,stop_time));

</script>

这是转过来的一段代码,里面也有点东东不太明白:

d1.replace(/-/g,"\/")

 

这里的正则怎么理解啊,请指教!

 

二、在js中格式化时间

  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;
}
//上面的函数必须在上面(先定义后使用),不然无法识别format()

var ddd = new Date();
alert(ddd.format('yyyy-MM-dd'));

可以配合使用,来判断时间,呵呵
