ng-重复不从数据库绑定



我有一个 1 页的应用程序,它应该显示数据库中的对象列表。 我使用 ng-repeat 创建了一个模板来绑定数据库中数组中的数据。由于我是 Angular 的新手,任何帮助都会很棒。 我的代码如下:

SERVER.JS
var express = require('express');
var app = express();
var mongojs = require('mongojs');
var db = mongojs('eventlist', ['eventlist']);
var bodyParser = require('body-parser');
app.use(express.static(__dirname + "/public"));
app.use(bodyParser.json());
app.get('/eventlist', function (req, res) {
console.log("i received a get request")
db.eventlist.find(function(err, docs){
console.log(docs);
res.json(docs);
});
});
app.post('/eventlist', function (req, res){
console.log(req.body);
db.eventlist.insert(req.body, function (err, doc) {
res.json(doc);
});
});
app.delete('/eventlist/:id', function(req, res){
var id = req.params.id;
console.log(id);
db.eventlist.remove({_id: mongojs.ObjectID(id)}, function (err, doc) {
res.json(doc);
});
});
app.get('/eventlist/:id', function (req, res) {
var id = req.params.id;
console.log(id);
db.eventlist.findOne({_id: mongojs.ObjectId(id)}, function (err, doc) {
res.json(doc);
});
});
app.put('/eventlist/:id', function (req, res) {
var id = req.params.id;
console.log(req.body.name);
db.eventlist.findAndModify({
query: {_id: mongojs.ObjectId(id)},
update: {$set: {name: req.body.name, startDate: req.body.startDate, price: req.body.price, location: req.body.location}},
new: true}, function (err, doc) {
res.json(doc);
}
);
});
app.listen(4000);
console.log("Server running on port 4000");

CONTROLLER.JS
var myApp = angular.module('myApp', []);
myApp.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
console.log("Hello World from controller");
var refresh = function(){
$http.get('/eventlist/').then(function(response) {
console.log("I got the data I requested");
$scope.eventlist = response;
$scope.event = null;
});
};
refresh();
$scope.addEvent = function () {
console.log($scope.event);
$http.post('/eventlist/', $scope.event).then(function(response){
console.log(response);
refresh();
});
$scope.update = function() {
console.log($scope.event._id);
$http.put('/eventlist/' + $scope.event._id, $scope.event).then(function(response) {
refresh();
})
};
};
$scope.remove = function(id) {
console.log(id);
$http.delete('/eventlist/' + id).then(function(response) {
refresh();
});
};
$scope.edit = function(id) {
console.log(id);
$http.get('/eventlist/' + id).then(function(response) {
$scope.event = response;
});
};
$scope.deselect = function() {
$scope.event = null;
refresh();
};
}]);

将其更改为response.data

var refresh = function(){
$http.get('/eventlist/').then(function(response) {   
$scope.eventlist = response.data;
$scope.event = null;
});
};
