中国标准时间格式转换成常用时间格式
Mon Aug 29 2016 15:07:30 GMT+0800 (中国标准时间) --> 2016-08-29 15:07:30
方法一：
1 //获取日期时间格式化字符串
2 var getDateStringFromString = function(str,isAll){
3 var date = new Date(str);
4 var hour = date.getHours();
5 hour = (hour < 10 ? "0" : "") + hour;
6 var min = date.getMinutes();
7 min = (min < 10 ? "0" : "") + min;
8 var sec = date.getSeconds();
9 sec = (sec < 10 ? "0" : "") + sec;
10 var year = date.getFullYear();
11 var month = date.getMonth() + 1;
12 month = (month < 10 ? "0" : "") + month;
13 var day = date.getDate();
14 day = (day < 10 ? "0" : "") + day;
15 if(isAll){
16 return year + "-" + month + "-" + day + " " + hour + ":" + min + ":" + sec;
17 }else{
18 return year + "-" + month + "-" + day +" ";
19 }
20 };
21
22 console.log(new Date()); //Mon Aug 29 2016 15:07:30 GMT+0800 (中国标准时间)
23 console.log(getDateStringFromString(new Date())); //2016-08-29
24 console.log(getDateStringFromString(new Date(),1)); //2016-08-29 15:07:30
方法二：
1 //author: meizz
2 Date.prototype.format = function(format){
3 var o = {
4 "M+" : this.getMonth()+1, //month
5 "d+" : this.getDate(), //day
6 "h+" : this.getHours(), //hour
7 "m+" : this.getMinutes(), //minute
8 "s+" : this.getSeconds(), //second
9 "q+" : Math.floor((this.getMonth()+3)/3), //quarter
10 "S" : this.getMilliseconds() //millisecond
11 }
12 if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
13 (this.getFullYear()+"").substr(4 - RegExp.$1.length));
14 for(var k in o)if(new RegExp("("+ k +")").test(format))
15 format = format.replace(RegExp.$1,
16 RegExp.$1.length==1 ? o[k] :
17 ("00"+ o[k]).substr((""+ o[k]).length));
18 return format;
19 }
20
21 var myFunction = function(){
22 var da= new Date();
23 var s=da.format("yyyy-MM-dd hh:mm:ss");
24 return s;
25 }
26
27 console.log(new Date()); //Mon Aug 29 2016 15:17:51 GMT+0800 (中国标准时间)
28 console.log(myFunction(new Date())); // 2016-08-29 15:17:51
