js Instructions for using = and = date functions (assignment operator)_javascript skills

var s= newDate();
The explanation is as follows: = does not exist;
new Date() is a thing;
is equivalent to .valueOf();
I will add .getTime after seeing the reply. ()This also gets the number of milliseconds

Copy code The code is as follows:

//4 results The same returns the number of milliseconds of the current time
alert( new Date());
alert( new Date);
var s=new Date();
alert(s.valueOf());
alert(s.getTime());

Comes with js for various usages of getting time:

Copy code The code is as follows:

var myDate = new Date ();
var a=myDate.toLocaleString( );
2011-11-07 18:13:56

By the way, another usage of valueOf:

The valueOf() method returns the original value of the Boolean object.

If the object on which this method is called is not a Boolean, a TypeError exception is thrown.

Copy code The code is as follows:

var boo = new Boolean(false);
document.write(boo.valueOf());
