Passing an array to server with signalR

Question

How do I pass an array of string in javascript to the server with SignalR?

I have an array in javascript and would like to this to a function to a Hub

var selected = new Array();
$('#checkboxes input:checked').each(function () {
    selected.push($("input").attr('name'));
});

What type of parameter should the function take?

Answer 1

The hub function can take an array of strings, a list of strings etc.

Here's an example hub:

public class myHub : Hub
{
    public void receiveList(List<String> mylist) 
    {
        mylist.Add("z");
        Caller.returnList(mylist);
    }
}

Here's an example JS piece to work with the hub:

var myHub = $.connection.myHub,
    myArray = ['a','b','c'];

myHub.client.returnList = function(val) {
    alert(val); // Should echo an array of 'a', 'b', 'c', 'z'
}

$.connection.hub.start(function() {
    myHub.server.receiveList(myArray);
});
