我试图以json格式从服务器(servlet)获取数据并添加到表中。数据从服务器端成功获取,当我使用console.log(数据)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);
}
的index.html
<html data-ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<!--<title>JSP Page</title>-->
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js" type="text/javascript"></script>
<script src="js/module/module.js" type="text/javascript" ></script>
<script src="js/controller/controller.js" type="text/javascript" ></script>
</head>
<body>
<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>
</body>

这是处理Angular中的promise的正确方法。在控制器中:
module.controller("ContactController", function($scope, $http, ContactService) {
ContactService.list().then(function(data) {
$scope.contacts = data;
});
}
然后修改了服务:
module.service('ContactService', function ($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();
}
});
然后最重要的是你应该从list
方法(和getContacts
)返回promise对象。

根据我现有的代码,只需更改 var contacts = [{}]; 至 var contacts = [];
或删除
var contacts = [{ }];
其次在$ http.get成功设置联系人:
response.success(function(data, status, header, config) {
$scope.contacts=data;
// console.log("contacts: " + contacts);
// return contacts;
});
“dfsq”的上述解决方案也非常好,并且非常适合执行。

您可以尝试以下方法。这是干净且易于管理的方式。您需要具有作为服务工作的AngularJS工厂,该工厂将委托给控制器类,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,然后你得到你的联系。所以这是代码:
<强>服务强>
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 $http.get("/PersonalDetail/AngularServlet").success(function(data){
return data;
})
}
};
});
<强>控制器强>
var module = angular.module('myApp', []);
module.controller('ContactController', ['$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);
})
}]);
<强>的index.html 强>
<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>
希望这有帮助:)
