Try:

'<%= System.DateTime.Now.ToString("yyyy-MM-dd"); %>';

I don't know why you put in the backslashes there, but you are not inside a string, so they are not necessary.

You can always do that in Pure Javascript, you can try download this Date Parse Library:

http://www.javascripttoolbox.com/lib/date/source.php

and then try something like this:

<script type="text/javascript" src="js/date.js"></script>
<script language="javascript">
 
var strDate = new Date().format("yyyy-MM-dd");
 
document.write(strDate);
 
</script>

the ";" is still there, wrong copy / paste, apologies. If you paste the following, and move with your mouse over the "move mouse" text, you will see the current date (name of the page Q_24312175.aspx, remove the first line(s) if you want to use it in your page, or add a form by that name).

I was going to suggest just get the data from Javascript like Ryan did. I didnt know there was a library involved though. Ryan, is that just for formatting?

Only methods I know is getyear(), getMonth() getDay(). Now these dont return leading zeros, so if u want that, you need to add it

eg

var currentDate = new Date();
var dStr = currentDate.getYear() + "/" + leadingZero(currentDate.getMonth()) + "/" +

leadingZero(currentDate.getDay());

alert(dStr);


and the leading zero function

function leadingZero(n)
{
      if (n < 10) n = "0" + n;
      return n;
}

> Thanks for all help.

you're welcome, glad we could have been of some help.

However, as a long-time regular to EE I have to point you to the fact that it is best to just split the points and not except your own comment (which is not an answer) as answer. That way, people visiting this question get the correct answer and the PAQ archive of EE stays proper.
