如何在另一个输入值（如 facebook 评论）下显示输入值？

Question

如何在打印值中创建另一个评论，如 facebook 评论。我希望在提交后显示该值时显示该值回复选项，当我单击回复时，将显示另一个输入框，以便我会再次评论该印刷值，就像 facebook 一样。我希望输入值在提交后会被清除。

谁能帮我找出这个问题？

$(document).ready(function(){
  $("#btn").click(function(){
    let getVal = $("#inputValue").val();
    let img = `<img src="https://images.unsplash.com/photo-1503023345310-bd7c1de61c7d?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80" class="rounded-circle" height="30px" width="30px">`
    $("#output").html($("#output").html() + " " + img + getVal + `<br>` );
  });
});

$(document).ready(function(){
  var replyHtml = "<br><input type='button' class='reply' value='reply'><div style='display:none;'><input type='text' placeholder='reply'><input type='button' class='rep-submit' value='reply'></div>";
  
  $("#btn").click(function(){
    let getVal = $("#inputValue").val() + replyHtml;
    let img = `<img src="https://images.unsplash.com/photo-1503023345310-bd7c1de61c7d?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80" class="rounded-circle" height="30px" width="30px">`
    $("#output").html($("#output").html() + " " + img + getVal + `<br>` );
    $("#inputValue").val('')
  });
  
  $(document).on('click', '.reply', function(){
    $(this).next().show();
    $(this).remove();
  });
  
  $(document).on('click', '.rep-submit', function(){
    var reply = $(this).prev().val();
    $(this).closest('div').html(reply + replyHtml);
  });

可以通过这样的方式完成-

$(document).ready(function(){
  $("#btn").click(function(){
    let getVal = $("#inputValue").val();
    let img = `<img src="https://images.unsplash.com/photo-1503023345310-bd7c1de61c7d?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80" class="rounded-circle" height="30px" width="30px">`
    let replyInput = '<div class="ml-5"><input type="text" id="replyText">&nbsp;&nbsp;<button class="btn btn-primary" type="button" id="reply">reply</button></div>'
    $("#output").html($("#output").html() + " " + img + getVal + `<br>`+ replyInput );
  });
});
