Get Ajax data into Angular grid
Using Angular Grid, I get the ajax get data in console.log. But an empty grid.
The console log reads:
[13:56:11.411] now!!
[13:56:11.412] []
[13:56:11.412] now!!
[13:56:11.556] <there is data returned from console.log(getData); >
This is the js file.
// main.js
var app = angular.module('myApp', ['ngGrid']);
var getData = [];
function fetchData() {
var mydata = [];
$.ajax({
url:'/url/to/hell',
type:'GET',
success: function(data) {
for(i = 0, j = data.length; i < j; i++) {
mydata[i] = data[i];
}
getData = mydata;
console.log(getData);
}
});
}
fetchData();
app.controller('MyCtrl', function($scope) {
console.log('now!!')
console.log(getData)
console.log('now!!')
$scope.myData = getData
$scope.gridOptions = {
data: 'myData',
showGroupPanel: true
};
});
New Js file:
// main.js
var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope, $http) {
function fetchData() {
$http({
url:'/url/to/hell',
type:'GET'})
.success(function(data) {
$scope.myData = data;
$scope.gridOptions = {
data: 'myData',
showGroupPanel: true
};
});
}
fetchData();
});
HTML file.
<html ng-app="myApp">
<head lang="en">
<meta charset="utf-8">
<title>Blank Title 3</title>

Answer
This would be much easier (and more Angular) if you defined a service for your request. Something along these lines:
angular.module('hellServices', ['ngResource'])
.factory('Hell', function ($resource) {
return $resource('URL/TO/HELL', {}, {
query: { method: 'GET' }
});
});
Make sure to include it in your app:
var app = angular.module('myApp', ['ngGrid', 'hellServices']);
Then you can get a promise for it in your controller:
app.controller('MyCtrl', function($scope, $http, Hell) {
$scope.myData = Hell.query();
And then set the grid options to look at the promise for its data (as you already did):
$scope.gridOptions = {
data: 'myData',
showGroupPanel: true
};
If you do this, you don't have to worry about $scope.$apply because it will be handled for you. This is much cleaner and easier to follow. If you still need a callback to modify the data once it's returned from the server, pass a function to the query() function of your service:
...
$scope.myData = Hell.query(function(hell) {
// code that modifies 'hell'
});
