如何让我的复印文本JS收听多个按钮？

function copyText() {
  var copyText = document.getElementById("myInput");
  copyText.select();
  document.execCommand("copy");
}

<input type="text" value="Hello World" id="myInput">
<button onclick="copyText()">Copy Text</button>

<input type="text" value="Lorem Ipsum" id="myInput2">
<button onclick="copyText()">Copy Text</button>

<input type="text" value="Sample Text" id="myInput3">
<button onclick="copyText()">Copy Text</button>

function copyText(inputId) {
  var copyText = document.getElementById(inputId);
  copyText.select();
  document.execCommand("copy");
}

<input type="text" value="Hello World" id="myInput">
<button onclick="copyText('myInput')">Copy Text</button>

<input type="text" value="Lorem Ipsum" id="myInput2">
<button onclick="copyText('myInput2')">Copy Text</button>

<input type="text" value="Sample Text" id="myInput3">
<button onclick="copyText('myInput3')">Copy Text</button>
