 Javascript how come the day before and one day after day?
Using Javascript how come the day before and one day after day? |
Some Subtraction
[html]
"Script>
Document.write (new Date (1998,4))
"/script>
[/html] |
Js itself will help you automatically calculate the date
[html]
"Script>
Alert ( "a day :" + new Date ( "2003/1/1"))
Alert ( "the day before :" + new Date ( "2003/1/0"))
Alert ( "a day :" + new Date ( "2003/1/31"))
Alert ( "day :" + new Date ( "2003/1/32"))
"/script>
[/html] |
You are wrong, so I have not made myself clear :
How do you show the same day the day before and one day after the date date
For example : Today is 2003-7-15, then today is the day before : 2003-7-14, the day after is : 2003-7-16
(Because of the different number of days per month, so special attention should be paid to the first day and the last day of each month)
Will experts advise! |
Simple realization :
[html]
"Script>
With (new Date ()) (
Y=getYear ()
M=getMonth ()
D=getDate ()
}
Document.write ( "yesterday :" +new Date (Y, M, D-1) + "" School Official Cites Use ")
Document.write ( "Today :" +new Date () + "" School Official Cites Use ")
Document.write ( "Tomorrow :" +new Date (Y, M, D + 1) + "" School Official Cites Use ")
"/script>
[/html]
The number of days per month to consider :
