can not access on click function of a css [duplicate]

Question

I have a code like this

  <form asp-controller="Products" asp-action="AddComment" asp-route-id="@Model.Id" id="CommentForm">
     <div class=" w-100 mt-1  ml-5 mr-5  d-block">
        <div class="d-inline-block">
           <lable class="product-subtitle">Name</lable>
            <input id="Name" type="text" class="reply-comment" value="@fullname" disabled />
         </div>
         <div class="d-inline-block ">
              <lable class="product-subtitle">Email</lable>
                 <input id="Email" type="email" class="reply-comment" value="@userEmail" />
         </div>
      </div>
      <div class="mt-1  ml-5 mr-5 d-block ">
         <textarea rows="3" class="reply-comment" id="Comment" name="Comment"></textarea>
        </div>
         <div class="mt-1  ml-5 mr-5 mb-4 d-flex  justify-content-end">
            <div>
              <a class="btn btn-primary btn-buy d-flex justify-content-center add-comment" data-id="0"  data-ischild="0" style=" background-color: #425fab;width:80px; padding:10px"><span>Send</span></a>
             </div>
          </div>
     </form>

and js

 $(".add-comment").click(function () {
    //some thing happens in here

});

this works fine. and I can access .add-comment.click() function , but in somepart I have to add the textarea by javascript like this

let divStr = "<div class='w-75 d-inline-flex'><textarea id='ChildComment' class='reply-comment w-100' ></textarea></div>";
    divStr = divStr + "<div class='w-25 d-inline-flex align-bottom' style='float:left; justify-content:left;'>";        
     divStr = divStr + "<a  class='btn btn-buy d-inline add-comment' data-id='" + commentId +"' data-ischild='1'><span class='mr-1 ml-1'> Send</span></a></div>";
      $("#" + commentId).append(divStr);

but the I can not enter .add-comment.click(function()) when I make the textarea by javascript

Answer 1

Try to change

 $(".add-comment").click(function () {
    //some thing happens in here

});

into this

 $(document).on('click', '.add-comment', function() {
    //some thing happens in here

});

The first one doesn't work because the item is added after the DOM is loaded.

Answer 2

This is because you're trying to attach a click event onto an element that has been dynamically added. Try this:

$(document).on('click','.reply-comment',function(){//do something})
