js比较两个日期的大小

function CompareDate(d1,d2)
{
  return ((new Date(d1.replace(/-/g,"/"))) > (new Date(d2.replace(/-/g,"/"))));
}
 
var current_time = "2007-2-2 7:30";
var stop_time = "2007-1-31 8:30";
alert(CompareDate(current_time,stop_time));

 弹出的值为true或者false

var curTime = new Date();
//2把字符串格式转换为日期类
var startTime = new Date(Date.parse(kc.begintime));
var endTime = new Date(Date.parse(kc.endtime));
 
//3进行比较
return (curTime>=startTime && curTime<=endTime);
