你可以试试这个..

 <!DOCTYPE html>
 <html>
 <body>

   Name: <input type="text" id="myText" >
   2nd Name : <input type="text" id="myText2" >
   <p>Click the button to change the value of the text field.</p>
    <button onclick="myFunction()">Try it</button>
      <script>
function myFunction() {
  document.getElementById("myText2").value = document.getElementById("myText").value;
   }
     </script>

 </body>
 </html>
