I hava a javascript array in my Razor view, and I am calling an GET action of controller from my MVC view using $.ajax. What should be the parameter type of the Controller action that will accept the Javascript array passed from view. I tried to keep it as "object", but it is showing it as "[object]" only and showing no properties at all. Any idea of how to achieve this?

You should include some code. – MDeSchaepmeester May 7 at 8:52
yes, agreed.. but its difficult to separate out only the code of interest. if anyone having instant idea.. – Nirman May 7 at 8:54
convert that {object} to an [array] before passing it. – Omar May 7 at 8:58

It completely depends upon the type of the values in your array.

Say, if you have an array of integers, like this:

var intArray = [1,2,3,4]

Then, in your controller, you'd have a List<int> as your parameter type, the Controller is clever enough to figure out the conversion for you.

However, if you're wanting something more advanced, which I'm guessing you are, such as:

var customArray = [{hello: "world", foo: "bar"}]

Then it's best to create a custom object in .NET, with hello and foo as properties, such as:

public CustomObject {
   public string hello { get; set; }
   public string foo { get; set; }
}

Then you can use CustomObject, or List<CustomObject> as your parameter type and the Controller will map the properties for you... like magic.

Just pass it in ajax and add traditional: true,

var ids = [0,1,2,3];

$.ajax({
   url: '@Url.Action("SomeAction", "Home")',
   type: 'POST',
   traditional: true,
   data: { array: ids },
   ...

Controller

public ActionResult SomeAction(int[] array){}

For object array

var objs = JSON.stringify(your_objects);

$.ajax({
   url: '@Url.Action("SomeAction", "Home")',
   type: 'POST',
   data: { array: objs },
   ...

controller

public ActionResult SomeAction(List<YourObjectType> array){}

You want to pass object array, right? – AliRıza Adıyahşi May 7 at 9:37
