How to set ASP.NET server time in Javascript

How do you set a textbox value to the equivalent of DateTime.Now in Javascript? I tried these

$('#LastUpdatedTime').val('<%= System.DateTime.Now %>');
$('#LastUpdatedTime').val('<%= System.DateTime.Now.ToString() %>');

Both set the value to the literal string <%= System.DateTime... instead of the time.

How about writing out the time on the main .aspx page in the header

<script type="text/javascript">
var now = <%= System.DateTime.Now %>;
</script>

and then doing

$('#LastUpdatedTime').val(now);

You just need to make sure that you name things appropriately so that the JS in the external file gets the value from the global scope.

You can't put server tags in a javascript file.

You have to put the code in a file that is handled by the ASP.NET engine, e.g. your .aspx file.

(It's possible to configure the server so that the ASP.NET engine also handles .js files, but that's not a good solution. Javascript files are cached more extensively than regular pages, so it's not certain that the server executes the code each time the file is used.)

Add a javascript function in the aspx which simply returns the server tag, then call this function from your .js file. i.e. in the ASPX add:

function GetTimeNow () { return '<%= System.DateTime.Now.ToString() %>';}

That code is fine. The problem is that your <%= System.DateTime.Now %> code is not being parsed as server side code. What's the rest of the page look like?

Edit: Since it's in an external JS file, you could always rename the ".js" file to ".aspx" so that ASP.Net would start processing it. Then you'd just have to change your <script> tags to use the ".aspx" name instead.

The other option is to configure your server to send ".js" files through the ASP.Net handler.

Do you have them inside <script> tags on the aspx page?

The aspx page should look something like this

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
</head>
<body>
    <form id="form1" runat="server">

<script type="text/javascript">
    //put your JAVASCRIPT here
    $('#LastUpdatedTime').val('<%= System.DateTime.Now %>');
    $('#LastUpdatedTime').val('<%= System.DateTime.Now.ToString() %>');
</script>
    </form>
</body>
</html>
