I have my variable in an aspx.cs , such as :
protected string myVar="Hello";
Now, if I go to my scripts.js file added as :
<head>
<script src="/scripts/scripts.js" type="text/javascript"></script>
</head>
and I try this :
var myVarJs="<%=myVar&>";
it doesnt get the .NET myVar value.
Is there a way to catch it or am I dreaming?

- There are ways that you can get ASP.Net to dynamically process .js files, however doing this sort of thing inside a .js file is a bad idea as it would probably break client side caching. The answer that Ivan has posted is a much better solution. – Justin Commented Sep 6, 2011 at 14:20
- I would like to see which is the best way to pass an Array to java script array ,maybe 2 dimensional String Array's . – Rosmarine Popcorn Commented Sep 6, 2011 at 14:37

Reset to default 7Insert the variable before the script:
<head>
<script type="text/javascript"> var myVarJs="<%=myVar%>"; </script>
<script src="/scripts/scripts.js" type="text/javascript"></script>
</head>
You can also register/render client script. So you can declare variables in the backend and then render the javascript variables.
I don't think it is possible to directly access C# variable in javascript code. As C# is client side and Javscript is server side.
Unless on the Asp page you save the variable in a hidden field or label as text which is not visible.
Asp:
<asp:HiddenField ID="hidden" runat="server" value="<%=strvariable %>" />
Javascript:
function Button_Click()
{
alert(document.getElementById('hidden').value);
}
So this would get the hidden field with the ID of "hidden".
This could work I think.
