How to retrieve User's CurrentCulter inside a external JS file?

Question

I need to get the User's CurrentCulture Currency GroupSeparator and DecimalSeparator value in a external JS file like below, but below lines of code is not getting the expected result. It is not fetching values instead remains the string as it is.

var thousands = '<%= System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberGroupSeparator %>';
var decimal = '<%= System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator %>';

In my application i need to apply currency formater for different users Culture.

Please help me.

not enough context to understand what exactly is the problem. Take a look at: http://stackoverflow.com/help/mcve — Adam Wolski, Jan 31 '17 at 11:54
do you need the culture as the same as the server or localized for each client? — mathiasfk, Jan 31 '17 at 11:58
@mathiasfk I'm already using jquery-maskMoney.js. I need to pass the currency decimal and group separator there only and that value should be user's culture specific — MarsRoverII, Jan 31 '17 at 12:30

You can not render razor variables on external javascript file.

But you could generate a view only javascript code without tags and change the headers from request.

For example

 <script src="http://yourdomain/mycontroller/methodthagenerateJavascript"></script>

Then in your controller method apply contentType application/javascript

    Response.ContentType = "application/javascript";

The variables like '<%= System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberGroupSeparator %>' get data from the server, so its no use for you.

On the client side, you have the navigator object with some information, like navigator.language. You can then use toLocaleString to format it.

var number = 1234.56;
var lang = navigator.language; //pt-BR
number.toLocaleString(lang); //1.234,56

Edit: To know only the separators you could do something like:

separators = 1000.1.toLocaleString().replace(/\d/g, '')
thousands = separators[0];
decimal = separators[1];
