Posting array of JSON objects to MVC3 action method via JQuery Ajax

Does the model binder not suport arrays of JSON objects? The code below works when sending a single JSON domain object as part of the Ajax post. However, when sending a array of JSON domain objects, the action parameter is null.

     VarDomains= [{ DomainName: ' Testt1 ', Price: ' 19.99 ', Available: True }, { DomainName: ' Testt2 ', Price: ' 15.99 ', Available: False }];$.Ajax({Type: ' POST ',Url: Url.Basketadddomain,DataType: "JSON", Data: Domains, Success: function  ( Baskethtml  { }, Error: function  (a , B, C)  { Alert ( ' A problem ocurred '  } });        

This is the action method:

public ActionResult AddDomain(IEnumerable<DomainBasketItemModel> domain){ ...

Any ideas if it was possible to does this?

You need:

VarDomains= {Domains: [...Your elements...]};$.Ajax({Type: ' Post ',Url:  ' Your-uri ' , Data: JSON stringify (domains: , Traditional: , Success: function  (data)  { ...  } });        

In general, check out the Request object in the debugger, you'll see what ' s being passed and get a idea of how to "speak" HTTP.

Note: Just found this out. The model binder chokes on nullable decimal properties like:

public decimal? latitude { get; set; }

So it won ' t bind the If you ' re posting to it with a JSON string of looks like this:

{"latitude":12.0}

But it'll work if your post something like this:

{"latitude":"12.0"}
