Approve multiple uses at once using Checkbox in knockout

Question

Hi,
I have a requirement to Approve or Reject selected users at once using checkbox in knockout.

I can able to approve single user by using the below code

UserViewModel.prototype.approveFromApplied = function (user) {

    var self = this;

    user.statusId = 2;

    if (confirm('Are you sure?')) {

        $.ajax({

            url: "Home/ApproveUser",

            cache: false,

            type: "POST",

            contentType: "application/json; charset=utf-8",

            data: ko.toJSON(user),

            success: function (data) {

                self.users.remove(function (item) {

                    return item.user_id === data[0].User_ID;

                });

                var u = self._map(data);

                self.users.pushAll(u);

            },

            complete: function () {

                //twittAlert("Broker(s) Approved successfully!", "success");

            },

            error: function (parameters) {

            }

        });

    }

};

 
And I can able to show the checkbox and also done the checkAll/uncheckall functionality. But after selecting some users I need to pass those users to controller. How can I do it using knockout

can some body help on this.
Thanks in advance,
Murali Krishna.
