Question

I have a Ajax form in my asp.net mvc application, which has a onSuccess callback as below:

function onSuccessReport(context)
        {
            $('reportChart').empty();

            var line1=@Html.GetStrippedString(context.Expenses);
}

I defined a html helper which accept an string an manipulte it and return a string.

What I pass to onSuccessReport, is a json result which has a structure like this:

But I cant send context.Expenses and the application throws syntax error.

How can I send a javascript variable to my helper?

Thanks

Edited:
The error in my view

****Error 1 The name ‘context’ does not exist in the current context****

C# method

json = json.Replace("\"Date\":", string.Empty);

            json = json.Replace("\"Total\":", string.Empty);

            json = json.Replace('}', ']');

            json = json.Replace('{', '[');

            return MvcHtmlString.Create(json);

Actually, you can send javascript values over to the server side if you use Ajax. Instead of using your helper method the way you are, just change it into an action within the Controller to return you some Json (could just be a string, number, object, etc, etc). Here is an example of what you might try out.

View

function onSuccessReport(context)
    {
        $('reportChart').empty();
        var expenses = context.Expenses;
        $.getJSON('@Url.Action("GetStrippedString", "ControllerName")', { expenses: expenses }, function (data) {
            //pending what you pass back as data, do whatever with it
            alert(data);
        });
 }

Controller

public JsonResult GetStrippedString(string expenses)
{
    var result = string.Empty;
    //Do something to string
    return Json(result, JsonRequestBehavior.AllowGet);
}
