I'm creating an iconic application and want to be able to load JSON strings from a web server into my application. So far, i can only get one message to load.
![That's what my application looks like so far. I can only get one message to load][1]
Here's my HTML code:
<body>
<ion-view view-title="Announcements">
<ion-content ng-controller="Controller">
<ion-refresher
pulling-text="Pull to refresh..."
on-refresh="doRefresh()">
</ion-refresher>
<ion-list>
<ion-item>
<div class="list card">
<div class="item item-divider">{{announcement_name}} - {{date}}</div>
<div class="item item-body">
<div>
{{message}}
</div>
</div>
</div>
</ion-item>
</ion-list>
</ion-content>
</ion-view>
</body>
Here's my javascript controller:
.controller('Controller', function($scope, $http) {
$scope.items = [1,2,3];
$scope.doRefresh = function() {
$http.get("")
.success(function(data) {
$scope.announcement_name = data.announcement_name;
$scope.date = data.date;
$scope.message = data.message;
})
.finally(function() {
$scope.$broadcast('scroll.refreshComplete');
});
};
});
And this is what my JSON file looks like. As you can see i have 2 arrays (messages) but only one is being loaded. Any idea why??
[
{
"response1": {
"announcement_name": "ExampleMessage1",
"date": "26/05/2015",
"message": "ExampleMessage1"
},
"response2": {
"announcement_name": "ExampleMessage2",
"date": "27/05/2015",
"message": "ExampleMessage2"
}
}
]
You should loop through your json-array with ng-repeat.
Here is an example:
$http.get("http://www.wikicode.co.uk/announcement.json")
.success(function(data) {
$scope.datafromservice = data;
})
.finally(function() {
...
});
And something like this in your html:
<div class="list card">
<div class="item item-divider" ng-repeat="message in data">{{message.announcement_name}} - {{messagedate}}</div>
</div>
Here is the doc to ng-repeat: https://docs.angularjs.org/api/ng/directive/ngRepeat
Hope, this helps.
UPDATE
You could paste the complete json in the var. Your json could look something like this (its an example from an app, I'm working on):
var reportapp = angular.module('reporting', []);
reportapp.controller('TreeController', ['$http', '$scope', function ($http, $scope) {
$scope.treedata = [];
$http.get('../data/tree.json').success(function (data) {
$scope.treedata = data;
});
//After the http-call your data should look something like this:
$scope.treedata = [
{
"name": "Titel",
"id": "1"
},
{
"name": "Allgemeine Standardangaben",
"id": "2"
},
{
"name": "Strategie und Analyse",
"id": "3",
"children": [
{
"name": "Erklärung des Entscheidungsträgers",
"id": "4"
},
{
"name": "Wichtigste Nachhaltigkeitsauswirkungen",
"id": "5"
}
]
}]
}]);
Then it's able to access the array with ng-repeat like:
<body ng-app="reporting">
<ul id="treecontainer" ng-controller="TreeController as treeCtrl">
<li ng-repeat="knoten in treedata" id="{{knoten.id}}">{{knoten.name}}
<ul ng-show="knoten.children">
<li ng-repeat="kind in knoten.children" id="{{kind.id}}">{{kind.name}}</li>
</ul>
</ul>
</body>
If yout want to show the children-nodes you can use ng-show:
If you have problems just post it here and I will try to help you.
