Copy code The code is as follows:

 
//Put a date string such as "2007-2-28 10 :18:30" converted to Date object 
var strArray=str.split(" "); 
var strDate=strArray[0].split("-"); 
var strTime=strArray[1 ].split(":"); 
var a=new Date(strDate[0],(strDate[1]-parseInt(1)),strDate[2],strTime[0],strTime[1], strTime[2]) 

2: The second method is really simple
var s = "2005-12-15 09:41:30";
var d = new Date (Date.parse(s.replace(/-/g, "/")));

var myDate = new Date();
var year=myDate.getYear(); //Get the current year (2 digits)
var year1=myDate.getFullYear(); //Get the complete year (4 digits, 1970-????)
var moonth=myDate.getMonth(); //Get the current month (0-11, 0 represents January)
myDate.getDate(); //Get the current day (1-31)
myDate.getDay (); //Get the current week ; //Get the current number of hours (0-23)
myDate.getMinutes(); //Get the current number of minutes (0-59)
myDate.getSeconds(); //Get the current number of seconds (0- 59)
myDate.getMilliseconds(); //Get the current milliseconds (0-999)
var mytime=myDate.toLocaleDateString(); //Get the current date//How is it in English?
var mytime =myDate.toLocaleTimeString(); //Get the current time
var a=myDate.toLocaleString( ); //Get the date and time

How to determine whether it is datetime type in js
1 Short time, in the form of (13: 04:06)

Copy code The code is as follows:

function isTime(str)

 { 
var a = str.match(/^(d{1,2})(:)?(d{1,2})2(d{1,2})$/); 
if (a == null) {alert('The input parameter is not in the time format'); return false;} 
if (a[1]>24 || a[3]>60 || a[4] >60) 
{ 
alert("Incorrect time format"); 
return false 
} 
return true; 
} 

 
2. Short date, in the form of (2008-07-22) 

Copy code The code is as follows:

function strDateTime(str)

{ 
var r = str.match(/^(d{1,4})(-|/)(d{1,2})2(d{1,2} )$/); 
if(r==null)return false; 
var d= new Date(r[1], r[3]-1, r[4]); 
return ( d.getFullYear()==r[1]&&(d.getMonth() 1)==r[3]&&d.getDate()==r[4]); 
} 

 
3 long time, shaped like (2008-07-22 13:04:06) 

Copy code The code is as follows:

function strDateTime(str)

{ 
var reg = /^(d{1,4})(-|/)(d{1,2})2(d{ 1,2}) (d{1,2}):(d{1,2}):(d{1,2})$/; 
var r = str.match(reg); 
 if(r==null)return false; 
var d= new Date(r[1], r[3]-1,r[4],r[5],r[6],r[7] ); 
return (d.getFullYear()==r[1]&&(d.getMonth() 1)==r[3]&&d.getDate()==r[4]&&d.getHours()= =r[5]&&d.getMinutes()==r[6]&&d.getSeconds()==r[7]); 
}
