You may do something like this.

<script type="text/javascript">
    function abc(players) {
        var t = document.getElementById("name").value;
        for(p in players) {
        if (t == p.Name) {
            alert("This name is already use!");
        }                
    }

    abc(@Html.Raw(Json.Encode( Model )));
</script>

You cannot use JS variables in C# code , but you can use C# variables in the code. In most cases C# is used to render HTML or JS.

In your case it would be best if you render your C# serverside model as a JS array , which you can later on iterate.

  1. make an action that returns your list (assuming it's a list) as a JSON

  2. fetch the data with an AJAX get call to your action.

Cheers!
