Wie kann ich Daten zwischen den Controllern AngularJS in meinem Fall senden? Ich möchte Ergebnis von gescanntem QR-Code in Dinge [] senden und, natürlich, zeigen Sie es. Ich bin Anfänger in AngularJS und JavaScript und machen dieses Programm nur für michWie kann ich Daten zwischen den Steuerungen senden AngularJS
App.js:
var MKscanner = angular.module('starter', ['ionic', 'ngCordova', 'ngStorage'])
MKscanner.controller('scanBarCtrl', function($scope, $cordovaBarcodeScanner) {
$scope.input ={
MyText : ''
};
$scope.scanBarcode = function() {
$cordovaBarcodeScanner.scan(
{
preferFrontCamera : false,
orientation : 'portrait'
}).then(function (result) {
alert(result.text);
},
function (error) {
alert('Scanning failed: ' + error);
});
};
});
MKscanner.factory ('StorageService', function ($localStorage) {
$localStorage = $localStorage.$default({
things: []
});
var _getAll = function() {
return $localStorage.things;
};
var _add = function (thing) {
$localStorage.things.push(thing);
}
var _remove = function (thing) {
$localStorage.things.splice($localStorage.things.indexOf(thing), 1);
}
return {
getAll: _getAll,
add: _add,
remove: _remove
};
});
MKscanner.controller('MainCtrl', function ($scope, StorageService) {
$scope.things = StorageService.getAll();
$scope.add = function (newThing) {
StorageService.add(newThing);
};
$scope.remove = function (thing) {
StorageService.remove(thing);
};
});
<div ng-controller="MainCtrl">
<div class="list">
<div class="item item-input-inset">
<label class="item-input-wrapper">
<input type="text" placeholder="Save your own text" ng-model="newThing">
</label>
<button class="button button-clear button-positive icon" ng-click="add(newThing)">
<i class="ion-ios-plus-outline"></i> Add
</button>
</div>
</div>
<ion-list show-delete="false" can-swipe="true">
<ion-item ng-repeat="thing in things">
{{thing}}
<ion-option-button class="button-assertive ion-trash-b" ng-click="remove(thing)"></ion-option-button>
</ion-item>
</ion-list>
</div>
