我只是想显示用户放在评论框中的评论。但是，我遇到了问题，因为它在ng-repeat指令中。让我展示一下，你可以更直观地理解：

这是我的app.js：
var app = angular.module("MyApp", []);
app.controller("HomeController", ["$scope", "$http", function($scope, $http) {
$scope.data = [];
$scope.search = "";
$scope.comment = "";
$scope.activeActor = {};
$scope.changeActiveActor = function(index) {
$scope.activeActor = index;
}
$scope.postComment = function(index, comment) {
console.log('comment ', comment);
//$scope.data[index].comments = [];
$scope.data[index].comments.push(comment);
console.log($scope.data[index]);
}
$scope.countUp = function(index) {
$scope.data[index].activity_likes++;
}
$scope.countDown = function(index) {
$scope.data[index].activity_likes--;
}
$http.get("https://nuvi-challenge.herokuapp.com/activities").then(function(response) {
console.log(response.data);
$scope.data = response.data;
})
}])
有人可以帮我看一下评论。当你开始玩它时，你会明白为什么它比问题听起来更难！
答案 0 :(得分：0)
这行有一些问题
<p ng-repeat="say in activity_comments">{{say}}</p>
当您将评论添加到
时$scope.data[index].comments.push(comment);
actor.comments 对象
将触及它们<p ng-repeat="say in actor.comments">{{say}}</p>
