Importing a JSON on angularJS with $http.get
Question
Im learnign angularJs, and i want to import an array from a json on my controller Like that:
myApp.controller("demoCtrl", function ($scope, $http) {
var promise = $http.get("todo.json");
promise.then(function (data) {
$scope.todos = data;
});
});
and im using a table to display the data on todos :
<table class="table">
<tr>
<td>Action</td>
<td>Done</td>
</tr>
<tr ng-repeat="item in todos">
<td>{{item.action}}</td>
<td>{{item.done}}</td>
</tr>
</table>
and this results on the flowing html page:
<!DOCTYPE html>
<html ng-app="demo">
<head>
<title>Example</title>
<link href="../css/bootstrap.css" rel="stylesheet" />
<link href="../css/bootstrap-theme.css" rel="stylesheet" />
<script src="angular.js"></script>
<script type="text/javascript">
var myApp = angular.module("demo", []);
myApp.controller("demoCtrl", function ($scope, $http) {
var promise = $http.get("todo.json");
promise.then(function (data) {
$scope.todos = data;
});
});
</script>
</head>
<body ng-controller="demoCtrl">
<div class="panel">
<h1>To Do</h1>
<table class="table">
<tr>
<td>Action</td>
<td>Done</td>
</tr>
<tr ng-repeat="item in todos">
<td>{{item.action}}</td>
<td>{{item.done}}</td>
</tr>
</table>
</div>
</body>

The normal way of getting access to the json is from the data within the returned object from the http request - you are tying to use the entire returned object.
I use "response" as the return from the get request - then the data is "response.data". This is needed because there are other properties returned within the response object from the get request.
Try changing your promise to be as follows:
promise.then(function (response) {
$scope.todos = response.data;
});
Also you should be having a thead and th's and tbody in the table to show a more semantically correct table
<table class="table">
<thead>
<tr>
<th scope="col">Action</th>
<th scope="col">Done</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in todos">
<td>{{item.action}}</td>
<td>{{item.done}}</td>
</tr>
</tbody>
</table>

Promise return entire response in callback Data is in response.data
myApp.controller("demoCtrl", function ($scope, $http) {
var promise = $http.get("todo.json");
// Entire response in callback
promise.then(function (response) {
$scope.todos = response.data; // Data is in response.data
});
});
