我在html中的示例代码：

<a class="btn btn-outline-info" href="#exampleModal" data-toggle="modal" data-target="#exampleModal" target="_blank" role="button">Click me
        <i class="fa fa-sign-in ml-2"></i>
      </a>
     <?php print $output; ?>
 <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true" data-backdrop="false">
 <div class="modal-dialog modal-dialog-centered" role="document">
    <div class="modal-content">

        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
          <center><h5><p> Do you have existing account? </p></h5></center>
      </div>
      <div class="modal-footer">

        <a href="sample.html" class="btn"   data-dismiss="modal" style="margin-right:220px; color:#fff; background:#00bcd4" href="#exampleModal2" data-toggle="modal" data-target="#exampleModal2" target="_blank" role="button">Yes</a>

                 <div class="invalid-feedback">

          </div>
</form>


      </div>
    </div>
      </div>
      </div>

这是我的php代码：

 <?php
    include_once('connection.php');
    $output = '';
    if(isset($_POST['search'])){
      $searchq = $_POST['search'];
      $sql =  "SELECT id, fname, lname FROM test WHERE id ='$searchq'" ;
      $result = mysqli_query($conn, $sql);
      $count = mysqli_num_rows($result);
        if($count == 0){
              $output ='No results!'; 
        }else{
            while($row = mysqli_fetch_array($result))
            {
              $fname = $row['fname'];
              $lname = $row['lname'];
              $id = $row['id'];
              $output .= '<div>'.$fname.''.$lname.'</div>';
             $InsertSql="INSERT INTO test(fname,lname,id) VALUES ('$fname','$lname','$id')";
            $res = mysqli_query($conn, $InsertSql);
            }
          }
        }  
    ?>

这是我的JavaScript代码：

<script>
    function success() {
     if(document.getElementById("textsend").value==="") { 
            document.getElementById('button').disabled = true; 
        } else { 
            document.getElementById('button').disabled = false;
        }
    }
    </script>


<script type="application/javascript">

  function isNumberKey(evt)
      {
         var charCode = (evt.which) ? evt.which : event.keyCode
         if (charCode > 31 && (charCode < 48 || charCode > 57))
            return false;

         return true;
      }

</script>

这是我当前的输出： sample output
