How to implement a PUT call with JSON data using AJAX and JQuery?

Question

I've looked around and tried many different methods, but can't seem to pass actual data to my controller's function.

Here is some code:

        var URL = "/Timesheet/Timesheet/UpdateEntry";

        var dataObject = { 'newWeekEntry': newEntry, 'oldWeekEntry': oldEntry };

        alert(JSON.stringify(dataObject));

        $.ajax({
            url: URL,
            type: 'PUT',    
            data: JSON.stringify(dataObject),
            dataType: 'json',
            success: function(result) {
                alert("success?");
            }
        });

newEntry and oldEntry are both objects.

The alert line outputs this (with some properties removed, just for brevity):

{"newWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":"4","SaturdayHours":0,"SundayHours":0},"oldWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":2,"SaturdayHours":0,"SundayHours":0}}

When I debug my controller action ("UpdateEntry"), the two parameters are filled with the TimesheetEntry class default parameters (0).

Am I passing this in properly?

The dataType attribute is only used when you're getting data from the server. You should be setting contentType to application/json when sending data to the server.
