The code after "@" is executed server-side before the resulting html is sent to the browser. "j" exists as a javascript variable when the html runs in the browser, so you can't use it in your server-side code as it doesn't exist in that context. You need to construct all of the js using server code, something like this

function onAdditional() {
    debugger;
    var ParamArray = new Array();
    var points;

    @foreach(var m in Model.objDllCollection)
    {
        string p = string.Format("points = {0};\r\nParamArray.push(points);\r\n", Json.Encode(m.Parameters));
        @Html.Raw(p);
    } 
}
