Good morning all.

I'm in the process of converting my VB Script form editing code to JavaScript.

I need to create two edits:

1) Check for valid date.

   In VB script I would use this code:

        if isdate(strDate) then..................

    is there an equivalent in JavaScript?

2) Determine time span between dates.

    In VB script I would use this code:

        if datediff("D",now,strdate) > 0 then...............

    is there an equivalent in JavaScript?

Thank you for your help!

i didnt get your first question ... do u mean to check the date from a user input in form or other means?? i wasn't clear about that

but regards to your second question... here is a possible solution:

suppose you want to find the difference of time between jan 10 1990 and jan 10 2000, here is what your could do :

var fDate=new Date("10 Jan 1990");
var sDate=new Date("10 Jan 2000");

var dateDiff=(sDate.valueOf()-fDate.valueOf());

/*the variable dateDiff now contains the difference between the two dates in milliseconds, which you can convert to any required time unit...all done by the valueOf() method of the date object */
