在Angular中发出HTTP POST请求后刷新内容的正确方法是什么？
//controller.js
var hudControllers = angular.module('hudControllers', []);
hudControllers.controller('PropertyDetailsCtrl',
['$scope','$window','$http', function ($scope,$window,$http) {
//I want to reload this once the newCommentForm below has been submitted
$http.get('/api/comments')
.success(function(data) {$scope.comments = {"data":data};}})
.error(function(data) {...);
$scope.newCommentForm = function(){
newComment=$scope.newComment;
requestUrl='/api/comments';
var request = $http({method: "post",url: requestUrl,data: {...}});
request.success(function(){
//How do I refresh/reload the comments?
$scope.comments.push({'comment':'test'}); //Returns error - "TypeError: undefined is not a function"
});
};
}]);
//template.ejs
<div class="comment">
<ul>
<li ng-repeat="comment in comments.data">{{comment.comment}}</li>
</ul>
</div>
谢谢。

有很多方法可以做到。我仍然想向您展示最简单的方法(根据您的需求)。
假设您有“first.html”页面，并且“PropertyDetailsCtrl”已与该页面相关联。
现在，您可以在html中这样写:
with very first-div
<div ng-controller="PropertyDetailsCtrl" ng-init="initFirst()">
.... Your page contents...
</div> (This will initialize your controller and you will have execution of your first method 'initFirst()'.
在您的.js端...
var hudControllers = angular.module('hudControllers', []);
hudControllers.controller('PropertyDetailsCtrl',
['$scope','$window','$http', function ($scope,$window,$http) {
//I want to reload this once the newCommentForm below has been submitted
$scope.initFirst=function()
{
$http.get('/api/comments')
.success(function(data) {...})
.error(function(data) {...);
//You need to define your required $scope.....
$scope.myVariable=data;
};
现在在适当的时间(您知道何时)，将调用以下方法。
$scope.newCommentForm = function(){
newComment=$scope.newComment;
requestUrl='/api/comments';
var request = $http({method: "post",url: requestUrl,data: {...}});
request.success(function(data){
//How do I refresh/reload the comments?
//without calling anything else, you can update your $scope.myVariable here directly like this
$scope.myVariable=data
});
//or else you can call 'initFirst()' method whenever and wherever needed like this,
$scope.initFirst();
};
}]);
我希望这将有所帮助。
