问题描述
我试图建立一个网站来喜欢一些图片.
I try to buil a website to like some pictures.
我可以加载图片,但我想有一个喜欢图片的点赞系统.
I can load the picture, but I want to have a like system with who like the picture.
我的问题是我必须刷新页面才能看到谁喜欢这张图片并增加计数.
my problem was I have to refresh the page to see who like this picture and increment the count.
这是我的控制器:
$scope.loadingpics = function (){
$http.get('/api/photos')
.success(function(awesomeThings) {
console.log(awesomeThings);
$scope.firstname = awesomeThings;
})
.error(function (err){
$scope.errors.other = err.message;
});
};
$scope.upVote = function(index){
$scope.vote = 1;
var ref = index;
var nom = index.url.substr(30, 40);
var num = index.vote + 1;
$http.put('api/photos/' + nom, {
email: email,
vote: num
})
.success(function (data) {
$scope.firstname = data;
$scope.loadingpics();
})
.error(function (err){
$scope.errors.other = err.message;
});
};
这是我的观点:
<li ng-repeat="image in firstname | orderBy: 'firstname'" ng-show="isLoggedIn()" class="thumbnail" title="Image 1" on-last-repeat>
<img ng-src="../assets/images/Pouce.png" ng-click="upVote(image)" data-toggle="popover" data-content="And here's some amazing content. It's very engaging. Right?" data-placement="right" title="Popover title">
</li>
这是我的架构:
var PhotoSchema = new Schema({
url: String,
firstname: String,
email: [String],
info: String,
vote: Number,
active: Boolean
});
感谢您的帮助 :D
推荐答案
我只是通过添加 $scope.watch 和 $scope apply 来更改我的 upVote 函数.
I just change my upVote function by adding a $scope.watch and $scope apply.
这是我的例子:
$scope.upVote = function(index){
$scope.vote = 1;
var ref = index;
var nom = index.url.substr(30, 40);
console.log(nom);
console.log(index.vote);
var num = index.vote + 1;
console.log(index);
$http.put('api/photos/' + nom, {
email: email,
})
.success(function (data) {
$scope.firstname = data;
})
.error(function (err){
$scope.errors.other = err.message;
});
$scope.$watch($scope.firstname, $scope.loadingpics());
$scope.apply();
};
