Passing Multiple Checkbox value using jquery ajax - asp.net-mvc

Question

I am displaying multiple records on my ASP.NET MVC 4 view where each record has a checkbox. I want the user to be able to select multiple records (by checking checkboxes) and click Delete button in order to delete them. So far I can call the Delete Action method via jquery ajax but the problem is my action method does not seem to be accepting the passed array.
Here is my jquery code:
$(function () {
$.ajaxSetup({ cache: false });
$("#btnDelete").click(function () {
$("#ServicesForm").submit();
});
$("#ServicesForm").submit(function () {
var servicesCheckboxes = new Array();
$("input:checked").each(function () {
//console.log($(this).val()); //works fine
servicesCheckboxes.push($(this).val());
});
$.ajax({
url: this.action,
type: this.method,
data: servicesCheckboxes,
success: function (result) {
if (result.success) {
}
else {
}
}
});
return false;
});
});
and here is my action method:
[HttpPost]
public ActionResult DeleteServices(int[] deleteservice)
{
if (deleteservice != null)
{
//no hit
}
}
What am I missing?
Edit
I also tried console.log(servicesCheckboxes); before $.ajax() which outputs ["3", "4"] but still get null when I pass data as specified in answer below data: { deleteservice: servicesCheckboxes }. Even I tried data: [1,2] but still action method shows null for deleteservice in action method.

Just pass the array to your action:
$.ajax({
url: this.action,
type: this.method,
dataType: "json"
data: { deleteservice: servicesCheckboxes }, // using the parameter name
success: function (result) {
if (result.success) {
}
else {
}
}
});
Or, just use the serialize() jquery method to serialize all fields inside your form:
$.ajax({
url: this.action,
type: this.method,
dataType: "json"
data: $(this).serialize(),
success: function (result) {
if (result.success) {
}
else {
}
}
});
In your controller:
[HttpPost]
public ActionResult DeleteServices(int[] deleteservice)
{
bool deleted = false;
if (deleteservice != null)
{
// process delete
deleted = true;
}
return Json(new { success = deleted });
}

Finally got it working. "MVC detects what type of data it receive by contentType" as explained here so I made the following changes to $.ajax()
$.ajax({
url: this.action,
type: this.method,
dataType: "json"
//data: { deleteservice: servicesCheckboxes }, // using the parameter name
data: JSON.stringify({ deleteservice: servicesCheckboxes }),
contentType: 'application/json; charset=utf-8',
success: function (result) {
if (result.success) {
}
else {
}
}
});
