这里有一个正确的方法来处理你的承诺。在控制器中:
module.controller("ContactController", function($scope, $http, ContactService) {
ContactService.list().then(function(data) {
$scope.contacts = data;
});
}
然后修改服务:
module.service('ContactService', function ($http) {
this.getContacts = function () {
return $http.get("/PersonalDetail/AngularServlet").then(function (data, status, header, config) {
return contacts;
}, function (data, status, header, config) {
return null;
});
}
this.list = function () {
return this.getContacts();
}
});
然后最重要的是,您应该从
list
方法(和getContacts
)返回promise对象
var contacts=[{}]至var触点=[]强>
或者移除
var contacts = [{ }];
其次,在$http.get的成功中,设置联系人如下:
response.success(function(data, status, header, config) {
$scope.contacts=data;
// console.log("contacts: " + contacts);
// return contacts;
});
上述由“dfsq”提出的解决方案也很好,而且非常适合执行。您可以尝试以下方法。这是一种干净且易于管理的方法。您需要使用AngularJS工厂作为服务,它将委托给控制器类,您的联系人将被推送到自己的数组范围。然后你可以简单地在前端循环,你就可以得到你的联系人。下面是代码: 服务
var module = angular.module('myApp', []);
module.factory('ContactService', ['$http', function($http) {
return {
//You can add as many REST calls inside this return as you want
getContacts: function(){
return $http.get("/PersonalDetail/AngularServlet").success(function(data){
return data;
})
}
};
});
控制器
var module = angular.module('myApp', []);
module.controller('ContactController', ['$http', '$scope', 'ContactService', function($http, $scope, ContactService){
$scope.contacts = [];
ContactService.getContacts().success(function(data){
//Depending on data structure in your REST call you might need first to loop the data
$scope.contacts.push(data);
})
}]);
index.html
<div data-ng-controller="ContactController">

希望这有帮助:)
