js 时间毫秒

1. "2014-08-18 00:00:00"  与　13位毫秒　互换

　　

 1 var oTime = {
 2 
 3      _format_13_time:function (str){
 4        var time = str.replace(new RegExp("-","gm"),"/");
 5        var haoMiao = (new Date(time)).getTime();
 6        return haoMiao;
 7     },
 8     _add_zero: function (str)
 9     {
10        if(parseInt(str) < 10){
11           str = "0" + str;
12        }
13        return str;
14     },
15     _format_date_time: function (str)
16     {
17        var d = new Date();
18        d.setTime(str);
19        var YMDHMS = d.getFullYear() + "-" + oTimeObj._add_zero((d.getMonth()+1)) + "-" + oTimeObj._add_zero(d.getDate()) + " "
20                     + oTimeObj._add_zero(d.getHours()) + ":" + oTimeObj._add_zero(d.getMinutes()) + ":" + oTimeObj._add_zero(d.getSeconds());
21        return YMDHMS;
22     }
23 
24 }

 var msec = Date.parse("March 21, 2012");   //13位毫秒数
