I have a tree which is created dynamically with json.There is a one controller and in this controller there is a json array.I use this json to create a tree,but i need to read this json from file externally.
My controller;
..........
$scope.myjson =
{
"option1": [
{
"child":[{"label":"Test1" },{"label":"Test2"}],
"id": "option1"
}
],
"option2": [
{
"child":[{"label":"Test1.1",}],
"id": "option2"
}
],
...........
}
Json array reading part(In Controller);
angular.forEach($scope.myjson, function(value, key)
{
if (key === 'option1')
{
for(var t=0;t<$scope.myjson[key][0].child.length;t++)
{
......Somethings.........
}
}
I want to call json file and read it to create a tree.How can i call json file and read in angularjs?
Reading JSON in Angular is pretty straightforward with $http. Keep in mind that $http will return a promise, and you need to resolve it before processing.
Here is a sample code:
$http.get('assets/messages.json').then(function (data) {
/** work with data **/
});
Here you can get a complete tutorial regarding your problem. You just need to modify it in your way.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="customersCtrl"> <ul> <li ng-repeat="x in names"> {{ x.Name + ', ' + x.Country }} </li> </ul> </div> <script> var app = angular.module('myApp', []); app.controller('customersCtrl', function($scope, $http) { $http.get("http://www.w3schools.com/angular/customers.php") .success(function(response) {$scope.names = response.records;}); }); </script>
