 }
 box.ondrop = function (e) {
  console.log(e.dataTransfer)
  e.preventDefault();
  var xhr = new XMLHttpRequest();
  xhr.onreadystatechange = function () {
  if (xhr.readyState == 4 && xhr.status == 200) {
   console.log(xhr.responseText)
  }
  }
  xhr.open('POST', './server.php', true);

  var formdata = new FormData();
  formdata.append('pic', e.dataTransfer.files[0]);
  formdata.append('name', 'luyao');
  xhr.send(formdata);

 }
 </script>
