AJAX & ASP.NET MVC 3: How to pass a string parameter AND an array at the same time to Controller

I have the following Controller signature:

public void DoSomething(string dialerJob, MyViewModel[] agentStates)

The viewModels represent form fields in an array (selected items in an HTML table). I figured out how to pass the form elements int as an array argument to the controller thanks to Robert Koritnik's .toDictionary() jQuery plug-in (http://erraticdev.blogspot.com/2010/12/sending-complex-json-objects-to-aspnet.html).

However, now I need to pass one additional string parameter (from a dropdown) to the controller and I cannot figure out how to make that work. I've tried various combinations, like:

 var job = $('#DialerJobs').attr('value');
 var data1 = $.toDictionary(data, "agentStates");

 $.ajax({
   url: "/Blending/ChangeOutboundJob",
   type: "POST",
   dataType: "application/JSON",
   data: {job, data1}
 });

I've also tried the following:

 var job = $('#DialerJobs').attr('value');
 var data1 = $.toDictionary(data, "agentStates");

 $.ajax({
   url: "/Blending/ChangeOutboundJob",
   type: "POST",
   dataType: "application/JSON",
   data: {dialerJob: job, agentStates: data1}
 });

But neither work.

If I remove the dialerJob parameter from the data to send, the agentStates populate in the controller correctly. And what gets sent looks like this:

agentStates[0].agentId=7654&agentStates[0].projectId=999&agentStates[0].stateId=1&agentStates

[0].subStateId=1&agentStates[1].agentId=9876&agentStates[1].projectId=999&agentStates

[1].stateId=1&agentStates[1].subStateId=1

But if I included the dialerJob, then what gets sent is:

dialerJob=SomeJob&agentStates[0][name]=[0].agentId&agentStates[0][value]=84&agentStates[1][name]=

[0].projectId&agentStates[1][value]=999&agentStates[2][name]=[0].stateId&agentStates[2][value]

=1&agentStates[3][name]=[0].subStateId&agentStates[3][value]=1&agentStates[4][name]=[1].agentId&agentStates

[4][value]=15884&agentStates[5][name]=[1].projectId&agentStat开发者_如何学JAVAes[5][value]=999&agentStates[6][name]=[1].stateId&agentStates[6][value]=1&agentStates[7][name]=[1].subStateId&agentStates[7][value]=1

Which is all messed up...

You could use a JSON request:

$.ajax({
    url: '@Url.Action("ChangeOutboundJob", "Blending")',
    type: 'POST',
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify({ 
        dialerJob: 'job', 
        agentStates: [
            { property1: 'value 1', property2: 'value 2' }, 
            { property1: 'value 3', property2: 'value 4' } 
        ] 
    }),
    success: function (result) {
        // TODO: process the results
    }
});

This will successfully map to the following controller action:

public void DoSomething(string dialerJob, MyViewModel[] agentStates)

where MyViewModel is defined like this:

public class MyViewModel
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
}

Remark: the JSON.stringify method is natively built into all modern browsers. If you need to support legacy browsers you need to include the json2.js script into your page.

change the js job var to be called dialerJob, the names must match for the mapper to auto map them.
