Parameter in razor helper inside javascript block

Question

I have this example code:

artists = data.split(";");
for (var i = 0; i < artists.length; i++) {
  $("#artistsLastStep").append("<div id='" + i + "'>" + '@MyHelper.Username(artists[i])' + "</div>");
}

I need put parameter to MyHelper.Username from javascript array artists.

Error from compiler: "The name 'artists' does not exist in the current context"

What i must to do ?

You can't mix javascript and .NET code like that, because when the C# code runs, you're on the server, not the browser, and by the time the javascript runs, you're already disconnected from the server. You have to redesign, possibly using AJAX calls to hit your server from javascript. — Joe Enos

Without knowing too much about the problem, I'd say something like:

function populateUsers(artists) {
    jQuery.ajax({
        url: "@Url.ActionLink("GetUsersDivs", "SomeControllerName")",
        dataType: "html",
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify({artistIds: artists})
    }).done(function(result) {
        jQuery("#artistsLastStep").html(result);
    });
}

This takes your array of artists, makes a single AJAX call to the server, which you'd just need a controller action to handle. The controller does the work of converting an artist ID into a name or object or whatever it is. You could then have a partial view which builds your div for a collection of artists and sends it back on the AJAX call.
