How to pass a javascript object to a C# MVC 4 controller

Question

In MVC4, how do you pass a javascript object to a C# controller in AJAX? Finally I tried this but it did not work.

Javascript Client side:

Answer 1

The value you pass for the data property should be an object, not a string:

data: myData,

the property names need to match:

var myData = { Prop1: '', Prop2: ''};

you need to use the [FromBody] attribute on your parameter value:

public ActionResult SubmitMyData([FromBody] MyParamModel myParam)

and the properties on your model type need to be public:

public class MyParamModel
{
    public string Prop1 { get; set; }
    public string Prop2 { get; set; }
}
