Loading JSON via AJAX with NgTable parameters

Question

I'm trying to use ngTables to sort and filter data using an AJAX call. Currently I am able to replicate the data with an ng-repeat, but none of my sorting functions apply. I referenced this example http://plnkr.co/edit/zuzcma?p=info and was able to get it to work using a mock.js file, but right now I'm using a file that I loaded onto my webserver and I can't seem to get it to work.

I'm sure the answer is fairly simple and appreciate any help. I've attached my markup to show you what my controller and html file look like. Thank you all and let me know if you need anymore information!

Here are some links to the API I am referencing.

HTML:

<div ng-controller="myController">
  <table ng-table="tableParams" show-filter="true" class="table table-condensed">
    <tr ng-repeat="user in data">
      <td data-title="foo" sortable="foo">{{user.foo}}</td>
      <td data-title="bar" sortable="bar">{{user.bar}}</td>
    </tr>
  </table>
</div>

Controller:

var app = angular.module('app', ['ngTable']);

app.controller('myController', function($scope, $http, $filter, ngTableParams) {

 $http.get('http://jsondata.com/myjson.json')
  .success(function(data, status) {
    $scope.data = data;
  });

$scope.tableParams = new ngTableParams({
    page: 1,            // show first page
    count: 10,          // count per page
    sorting: {
        foo: 'asc'     // initial sorting
    }
}, {
    total: data.length, // length of data
    getData: function($defer, params) {
        // use build-in angular filter
        var orderedData = params.sorting() ?
                            $filter('orderBy')(data, params.orderBy()) :
                            data;

        $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
    }
  });
});

you problem is that you use the local variable data inside your ngTableParams and in the same time you are outside the scope of the success function.

Change your code on something like this:

var app = angular.module('app', ['ngTable']);

app.controller('myController', function($scope, $http, $filter, ngTableParams) {

 $http.get('http://jsondata.com/myjson.json')
  .success(function(data, status) {
    $scope.data = data;

    $scope.tableParams = new ngTableParams({
        page: 1,            // show first page
        count: 10,          // count per page
        sorting: {
            foo: 'asc'     // initial sorting
        }
    }, {
        total: $scope.data.length, // length of data
        getData: function($defer, params) {
            // use build-in angular filter
            var orderedData = params.sorting() ?
                                $filter('orderBy')($scope.data, params.orderBy()) :
                                $scope.data;

            $defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
        }
      });
  });


});

See the change from data to $scope.data inside ngTableParams.

Hint: If you just place your ngTableParams inside your success function, is going to work too, without changing data to $scope.data. But, changing the variables will give you a better flexibility if you want to reload() your table.
