我在then()中返回了一些数据,我需要将它存储在“this”变量中.因为它没有存储在范围内,并且因为它包含在回调中,所以我的控制器的“this”无效.如何将数据冒泡,以便将其存储在“this”中？见下文：
angular.module('logisticsApp.controllers').
controller('InventoryCtrl',['$scope','$http','$window','DataService',function ($scope,$http,$window,DataService) {
this.inventory = ''; // need to have data stored here
$scope.$on('$viewContentLoaded',angular.bind(this,function() {
// "this" is still valid here
myService.getInventory().then(function(data) {
// "this" is no longer valid!
$scope.inventory = data; // so this fails
});
}));
}]);
解决方法
你可以使用angular.bind：
myService.getInventory().then(angular.bind(this,function(data) {
console.log(this.inventory);
}));
Returns a function which calls function fn bound to self (self becomes the this for fn).
您还可以保存对上下文的引用(this),如下所示：
var self = this;
myService.getInventory().then(function(data) {
console.log(self.inventory);
});
