如何在文本输入上自动聚焦？

<input type="text" autofocus>

<input type="text" id="myInput">

<script>
  window.onload = function() {
    document.getElementById("myInput").focus();
  };
</script>

<input type="text" id="myInput">

<script src="https://cdn.staticfile.org/jquery/3.5.1/jquery.min.js"></script>
<script>
  $(document).ready(function() {
    $("#myInput").focus();
  });
</script>
