JavaScript比较两个时间的大小和时间差

jopen 9年前
<script type="text/javascript">   $(function () {    ---------------------------------比较时间的大小-------------------------------------------------     var cha = (Date.parse("2010/1/14 9:00:00") - Date.parse("2010/1/12 8:00:00")) / 86400000 * 24;   if (cha > 0) {   alert(cha);   }    ---------------------------------比较时间的大小-------------------------------------------------      alert(daysBetween("2010-1-13 8:00:00", "2010-1-12 6:00:00"));    ---------------------------------得到当前时间-------------------------------------------------    var date = new Date();  now = date.getFullYear() + "/";  now = now + (date.getMonth() + 1) + "/"; //取月的时候取的是当前月-1如果想取当前月+1就可以了  now = now + date.getDate() + " ";  now = now + date.getHours() + ":";  now = now + date.getMinutes() + ":";  now = now + date.getSeconds() + "";  alert(now);    ---------------------------------得到当前时间-------------------------------------------------    -----------得到一个区域的时间,然后计算出时间差,并显示到指定的位置---------------------------  $(".cuttime").each(function () {  var txt = $(this).text();  var endtime = txt.substring(0, txt.indexOf('至'));  var starttime = txt.substring(txt.lastIndexOf('至') + 1);  var cuttime = (Date.parse(starttime) - Date.parse(endtime)) / 86400000 * 24;  alert(cuttime);  $(this).next("td").text(cuttime);  });    -----------得到一个区域的时间,然后计算出时间差,并显示到指定的位置---------------------------    alert(changetime("2010-1-12 8:00:00"))    });         //计算两个时间的时间差,根据你需要的样式进行修改    //比如2011$1$1,把“-”改成“$”  function daysBetween(DateOne,DateTwo)    {  var OneMonth = DateOne.substring(5,DateOne.lastIndexOf ('-'));    //计算两个时间相差几天时用的语句  //var OneDay = DateOne.substring(DateOne.length,DateOne.lastIndexOf ('-')+1);  var OneDay = DateOne.substring(DateOne.lastIndexOf('-') + 1, DateOne.indexOf(' '));  var OneYear = DateOne.substring(0, DateOne.indexOf('-'));  var OneHouse = DateOne.substring(DateOne.indexOf(' ') + 1, DateOne.indexOf(':'));        var TwoMonth = DateTwo.substring(5,DateTwo.lastIndexOf ('-'));  var TwoDay = DateTwo.substring(DateTwo.lastIndexOf('-') + 1, DateTwo.indexOf(' '));  var TwoYear = DateTwo.substring(0, DateTwo.indexOf('-'));  var TwoHouse = DateTwo.substring(DateTwo.indexOf(' ') + 1, DateTwo.indexOf(':'));    //计算两个时间相差几个小时  var cha = ((Date.parse(OneMonth + '/' + OneDay + '/' + OneYear) - Date.parse(TwoMonth + '/' + TwoDay + '/' + TwoYear)) / 86400000 * 24 + (OneHouse - TwoHouse));    //计算两个时间相差几天  //var cha = Date.parse(OneMonth + '/' + OneDay + '/' + OneYear) - Date.parse(TwoMonth + '/' + TwoDay + '/' + TwoYear)/ 86400000;               return Math.abs(cha);  }         //把2012-1-1 12:00:00转换成2012/1/1 12:00:00    function changetime(time) {  var Month = time.substring(5, time.lastIndexOf('-'));  var Day = time.substring(time.lastIndexOf('-') + 1, time.indexOf(' '));  var Year = time.substring(0, time.indexOf('-'));  var clock = time.substring(time.indexOf(' ') + 1);  return Year + '/' + Month + '/' + Day + " " + clock;  }         </script>         <body>  <table>  <tr><td class="cuttime">2010/1/14 12:00:00至2010/1/15 13:00:00</td><td></td></tr>  <tr><td class="cuttime">2010/1/14 9:00:00至2010/1/15 8:00:00</td><td></td></tr>  <tr><td class="cuttime">2010/1/14 9:00:00至2010/1/15 8:00:00</td><td></td></tr>  </table>  </body>
