Implementing event listeners with AngularJS after making a POST request

As I delve into the world of development, please forgive my lack of knowledge. My search for solutions brought me here. I am currently working on a comment and reply app. In order to add comments to my view, I am utilizing this specific function.

$scope.insertComment = function(){

    var new_comment_id = $scope.comments[$scope.comments.length - 1].commentID +1;
    var input = {
        "commentID" : new_comment_id,
        "userID": user.user_id,
        "name": user.user_name,
        "avatar_url": user.avatar,
        "says": $scope.new_comment,
        "likes": 0,
        "like_status": false,
        "replies": [] 
    };
    //Pushes changes to the global comment object
    $scope.comments.push(input);
    $scope.new_comment = '';
}

Every comment comes with an option to reply, triggered by the following event which displays a form for replying to the comment.

$(".no-url").click(function(){
    console.log('test2');
    $(this).parent().children('.reply-form').addClass('active');
});

My dilemma lies in the fact that newly added comments do not inherit this event listener. How can I resolve this issue?

Answer №1

Utilize directive in combination with jQLite

Example HTML :

 <div comment-click> 
    //insert your comment HTML here.
 </div>

Corresponding JS:

app.directive("commentClick",function(){

    return {
        link : function(scope,ele,attr){

            ele.on('click',function(){

                //place your comment script here

            })
        }
    }
})

Add the comment-click attribute to any new DOM element where you want to attach the click event

$(SELECTOR) will specifically target elements that exist in the DOM.

Event Delegation is a useful technique to consider.

$(PARENT_SELECTOR).on('click', '.no-url', function() {
  $(this).parent().children('.reply-form').addClass('active');
});

However, it's often better and more recommended to utilize the ng-click directive.
