这是我的消息传递代码，它包含div部分，用于显示表单部分包含的消息 输入标签和发送按钮以键入和发送消息，如何在该div部分显示消息
不使用发送按钮

    <div class="direct-chat-msg">

     <div class="">
    <span class="direct-chat-name float-left">
    </span> <span class="direct-chat-timestamp float-right"> 2:37 pm</span>
    </div>
    <img class="" src="#"alt="message user image">
    <table id="conversation"  >
    <tr>
     <tr>

    </tr>
    </table>
    </div>
    <form action="#" method="post">
    <div class="input-group">
    <input type="text" id="name"  placeholder="Type Message ..."class="form-control"> 
    <span class="input-group-append">
    <button  id="send" type="submit" onclick="myFunction()" class="btn btn-primary">Send</button>
    </div>

通过使用以下能够启用消息的javaScript iam

   <script>
  function myFunction() {
  var table = document.getElementById("conversation");
  var row = table.insertRow(0);
  var cell1 = row.insertCell(0);
  cell1.innerHTML ='<div class="direct-chat-text" id="greetings"></div>' ;
   }
  </script>

  But how to enable this without using send button i tried using triggering onclick Enter
