Javascript angular js跟踪喜欢和不喜欢的点击
我正在尝试在angularjs中开发应用程序，在这里我阅读json来阅读带有“喜欢”和“不喜欢”按钮的评论。我被困在一个点上，我不知道如何跟踪用户是否已经点击了Like以获得特定评论？？ data.json：：Javascript angular js跟踪喜欢和不喜欢的点击,javascript,jquery,angularjs,Javascript,Jquery,Angularjs,我正在尝试在angularjs中开发应用程序，在这里我阅读json来阅读带有“喜欢”和“不喜欢”按钮的评论。我被困在一个点上，我不知道如何跟踪用户是否已经点击了Like以获得特定评论？？ data.json：： [ { "name": "Anam", "age": 20, "id": 100, "commentline": "Yes Good !!!", "like":5, "dislike":1 }, { "name": "Mo

console.log('Likes increment'+a.name);
console.log($scope.comments.indexOf( a ) +'with index of name is '+$scope.comments[selectedIndex].name );

$scope.likeflag=1;
if($scope.likeflag==1)

}else
{
console.log('Already like');
}

});

我使用ng show和ng hide解决了这个问题 当likeClicked为false时，我显示like按钮，当用户单击它时，我将变量更改为false。因此，自动显示“不喜欢”按钮

$scope.incrlikes=function(a)
{
var selectedIndex=$scope.comments.indexOf( a );
if(! $scope.likeClicked[selectedIndex])
{
console.log('Likes increment'+a.name);
console.log($scope.comments.indexOf( a ) +'with index of name is '+$scope.comments[selectedIndex].name );
$scope.comments[selectedIndex].like=$scope.comments[selectedIndex].like+1;
$scope.likeClicked[selectedIndex]=true;

@每一个json对象的Stpal？这就是我被卡住的地方，对于每一条评论，我如何跟踪你想要什么？每个评论/每个用户？每个用户..我想跟踪每个用户然后你必须存储喜欢/取消链接的用户comment@Satpal看看假设我打开浏览器并喜欢“Jacob”的评论，那么它对应的喜欢应该增加1，然后再次点击喜欢，它应该显示一些消息，比如“已经喜欢什么了”
