angular js http request from aspx method - model-view-controller

Question

I have a page locations.aspx that has a method behind it in locations.aspx/getData. when I use the code
$http.jsonp($scope.url)
.success(function (data, status, headers, config) {
alert(data);
}).error(function (data, status, headers, config) {
$scope.status = status;
});
with the $scope.url being locations.aspx/getData it loads the html page of the aspx page but doesn't access the method. I can access the method using
$.ajax({
type: "POST",
url: $scope.url,
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (p) {
var temp = $.parseJSON(p.d);
$scope.allItems.push(temp);
},
error: function () {
alert('error');
}
});
but the data never updates or binds on the view side. An example on the html is
<select ng-model="selectLocation" id="selectLocation" ng-change="onLocationChange()">
<option></option>
<option ng-repeat="l in allItems">{{l.location}}</option>
</select>
After the ajax call allItems array does have an item in it but the view never updates.
My ajax call headers are
Request URL:localhost:41796/locations.aspx/getData
Request Method:POST
Status Code:200 OK
Request Headersview source
Accept:application/json, text/javascript, /; q=0.01
Content-Type:application/json; charset=utf-8
Response Headersview source
Cache-Control:private, max-age=0
Connection:Close
Content-Length:270
Content-Type:application/json; charset=utf-8
and my $http headers are
Request URL:localhost:41796/locations.aspx/getData
Request Method:GET
Status Code:200 OK
Request Headersview parsed
GET /locations.aspx/getData HTTP/1.1
Host: localhost:41796

Based on the discussion above, it seems you're using ASP.NET and running into specific issues with it.
ASP.NET can be pretty picky sometimes about what it will parse and what it won't -- especially when it comes to MVC (which it doesn't appear that you're using here, but perhaps [WebMethod] (what I assume you're using) has the same kinds of issues).
Instead of messing with jQuery's $.ajax, you can use Angular's $http in the same way:
$http({
method: 'POST',
url: $scope.url,
contentType: 'application/json; charset=utf-8'
})
.success(function (data, status, headers, config) {
alert(data);
})
.error(function (data, status, headers, config) {
$scope.status = status;
});
