javascript - Enter 键在单击按钮时不起作用

Question

大家好，我是 JavaScript 和编程的初学者。 我刚刚使用 html、css 和 javascript 进行了实时对话。 我无法访问按钮标签中的回车键。

<script>
  function typo(){
    var currentText = document.getElementById("demo").innerHTML;
    enterkey();
    var x = '<p class=chatbox>' + document.getElementById("myText").value + '</p>';
    document.getElementById("myText").value = "";
    var y = document.getElementById("demo").innerHTML = currentText + x;
  }

  function enterkey() {
    var input = document.getElementById("myText");
    input.addEventListener("keyup", function(event) {
      event.preventDefault();
      if (event.keyCode === 13) {
        document.getElementById("btn-chat").click();
      }
    });
  }
</script>

<p id="demo"></p>
<input type="text" id="myText" value="">
<button onclick="typo()" class="btn btn-warning btn-sm" id="btn-chat">Send</button>

<p id="demo"></p>
<input type="text" id="myText" value="">
<button onclick="typo()" class="btn btn-warning btn-sm" id="btn-chat">Send</button>
<script>
  function typo(){
    var currentText = document.getElementById("demo").innerHTML;
    var x = '<p class=chatbox>' + document.getElementById("myText").value + '</p>';
    document.getElementById("myText").value = "";
    var y = document.getElementById("demo").innerHTML = currentText + x;
  }
  
  var input = document.getElementById("myText");
  input.addEventListener("keyup", function(event) {
    event.preventDefault();
    if (event.keyCode === 13) {
      document.getElementById("btn-chat").click();
    }
  });
