knockout Validation - passing parameter from server side - asp.net-mvc-4

Question

I am working with knockout in MVC application. I am using knockout validation for validating the input. Everything is just fine,my problem is,I have a range validator for that input ll be coming from server view model.
how can I make that as my range validators minimum and maximum validation criteria?
since I am having all my code in separate js file I cant use # attribute.

Depending on how your code set up, you can use the # attribute (Razor code) as you said. Simply set a local variable on the page, then run your code that's in the external file, like this, where in your external js file, you can access min and max.
#* This is your razor .cshtml page *#
<script type="text/javascript">
var min = #ViewBag.Min;
var max = #ViewBag.Max;
</script>
<script type="text/javascript" src="../js/your-external-js"/>
Or, to keep things clean, you could use an initialize function:
#* This is your razor .cshtml page *#
<script type="text/javascript" src="../js/your-external-js"/>
<script type="text/javascript">
$(function() {
var min = #ViewBag.Min;
var max = #ViewBag.Max;
myExternalJs.Initialize(min, max);
});
</script>
