How to remove time portion of date using javascript?

[BobbyRachel]

i have a javascript variable which holds date time value... i need only date from it...

<script type="text/javascript">
    function update(){
    var datefield = document.getElementById("myTextBox_CWPWORKLIST.DUE_DATE").value;
    alert(datefield);
    }
    </script>

here the datefield = 2013-02-21 00:00:00.0... i need datefield = 2013-02-21.. how to get this..

var datefield = document.getElementById("myTextBox_CWPWORKLIST.DUE_DATE").value;
var s = datefield;
var n = s.slice(0, -10);
alert(n);


This code definitely meets your requirements i think.

Thank you.

here is my answer:

<script type="text/javascript">
    function update(){
    var datefield = document.getElementById("myTextBox_CWPWORKLIST.DUE_DATE").value;
    alert(datefield);
var columnname = dateFormat(datefield, "dd-mm-yy");
alert(datefield);
    }
    </script>

Your answer is incomplete - you haven't included the code for the dateFormat function you created and the part of the code that actually does what the OP asked is presumably somewhere in that function.

Ummm...Felgall: The "OP" here is the same person who wrote the non-answer that you commented on.

I think we have to assume he stole...err...copied...a dateFormat() function from someplace.

Which will not help the next person coming here searching for an answer to the same question as there still isn't an actual complete solution to the question published.

Since none of the code here actually validates what the field contains at all the first step would be to validate that the field actually contains a date/time and to load that into an appropriate JavaScript variable using new Date(). Then you can easily extract just the date portion using the appropriate methods.

Neither version of the code the OP posted would work if the person entered "noon yesterday" as their date and time even though the code they have would allow that input.

LOL! Well, crud. And here I wanted to be able to enter "my next birthday" and have JavaScript figure it out! What a truly worthless language. <grin/>

There's nothing in the OP's code to prevent you entering that and they claimed that everything now works so presumably the dateFormat function knows when your next birthday is.

LMAO! Touchė. I really and truly laughed out loud, not just grinned, when I read that!

Best laugh I've had all week except when my 2.5 year old granddaughter said "My cup disappeared." (You had to be there. It was mainly the shock of the big word, but the cup was right behind her.)
