js方法将系统时间转换为字符串案例：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>js将当前时间转换为字符串日期</title><script type="text/javascript" src="jquery-1.11.1.min.js"></script><script type="text/javascript">    $(function () {   $("#clickDate").click(function () {   var date=new Date();   alert("date:"+date);   dateStr=dateToString(date);   alert("dateStr:"+dateStr);   });});</script><script type="text/javascript">  function dateToString(now){    var year = now.getFullYear();    var month =(now.getMonth() + 1).toString();    var day = (now.getDate()).toString();    var hour = (now.getHours()).toString();    var minute = (now.getMinutes()).toString();    var second = (now.getSeconds()).toString();    if (month.length == 1) {        month = "0" + month;    }    if (day.length == 1) {        day = "0" + day;    }    if (hour.length == 1) {    hour = "0" + hour;    }    if (minute.length == 1) {    minute = "0" + minute;    }    if (second.length == 1) {    second = "0" + second;    }     var dateTime = year + "-" + month + "-" + day +" "+ hour +":"+minute+":"+second;     return dateTime;  }</script></head><body> <button  id="clickDate">系统当前时间转换为字符串</button></body></html>

备注：在实际开发中可以获得2个时间进行比较，时间必须已字符串的形式，否则无法进行比较
