Question

I am feeling dejavu, but I cannot find the answer to this:
I have an array of objects that needs to look like this when inspecting a jQ $.post call:

limiter[0].Key
limiter[0].Value

so that it is mapped in the action

public ActionResult SomeAction(Dictionary<Guid, string> dictionary) { }

However, this javascript:

// Some Guid and Some Value
var param = [ { 'Key' : '00000000-0000-00000-000000', 'Value': 'someValue' } ];

$.post('/SomeController/SomeAction/',
       {
       dictionary: limiter,
       otherPostData: data
       },
       function(data) {
          callback(data);
       }
)

produces this when inspecting it in firebug:

limiter[0][Key] = someKey // Guid Value
limiter[0][Value] = someValue

This is in jq 1.4.2. I seem to remember some flag you need to set to render json a different way in jQ. Does this ring any bells?

Try like this:

var param = {
    '[0].Key': '28fff84a-76ad-4bf6-bc6d-aea4a30869b1', 
    '[0].Value': 'someValue 1',

    '[1].Key': 'd29fdac3-5879-439d-80a8-10fe4bb97b18', 
    '[1].Value': 'someValue 2',

    'otherPostData': 'some other data'
};

$.ajax({
    url: '/Home/SomeAction/',
    type: 'POST',
    data: param,
    success: function (data) {
        alert(data);
    }
});

should map to the following controller action:

public ActionResult SomeAction(Dictionary<Guid, string> dictionary, string otherPostData) 
{ 
    ...
}
