我试图以json格式从服务器(servlet)获取数据并将其添加到表中。数据成功地从服务器端获取,当我使用console.log(data)时,它会打印数据,但不会将其添加到表中

module.js:

var module = angular.module('myApp', []);

module.service('ContactService', function($http) {

    var contacts = [{ }];
    this.getContacts = function($http) {
        var response = $http.get("/PersonalDetail/AngularServlet");
        response.success(function(data, status, header, config) {
            contacts=data;
            console.log("contacts: " + contacts);
            return contacts;
        });
        response.error(function(data, status, header, config) {
            return null
        });
        return contacts;
    }

    this.list = function($http) {
        return  this.getContacts($http);
    }
});
controller.js

module.controller("ContactController", function($scope,$http,ContactService) {
    $scope.contacts=ContactService.list($http);

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=[{}]var触点=[]

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">           
    <table class="table table-striped table-bordered" bgcolor="orange" border="1">
        <thead>
            <tr>
                <th>Name   </th>
                <th>Email  </th>
                <th>Phone  </th>
                <th>Action </th>
            </tr>
        </thead>
        <tbody>
            <tr ng-repeat="contact in contacts">
                <td>{{ contact.name}}</td>
                <td>{{ contact.email}}</td>
                <td>{{ contact.phone}}</td>                       
            </tr>
        </tbody>
    </table>
</div>
