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.

        <head lang="en">
            <meta charset="utf-8">

Solution

  • Your controller is probably accessing the getData array before the .success is finished. You're accessing the variable right away, outside of a promise function, which is initialized to an empty array.

    Why don't you try putting the fetchData function into the controller (for now) and storing the getData directly into $scope.myData in the .success? Maybe even initialize the grid right there too? Not sure if you can do that but if you could it would look like this:

    app.controller('MyCtrl', function($scope, $http) {  
    $scope.myData = '';
    $scope.gridOptions = { showGroupPanel: true, data: 'myData' };
    function fetchData() {
        setTimeout(function(){  
            $http({
                url:'/url/to/hell',
                type:'GET'})
                .success(function(data) {
                    $scope.myData = data;   
                    if (!$scope.$$phase) {
                        $scope.$apply();
                    }                   
                });         
        }, 3000);       
    }   
    fetchData();    
    });

    Also not sure why you're mixing in jQuery .ajax with angular code ($http will do that), and why none of your javascript has a semicolon.
