在完成函数jquery上重新加载表单

  • php
  • html
  • javascript
  • jquery

I want to pass an input value to a php session variable. With the code below, I can send the input value to the session but only appears in the alert box or if I refresh the page, which I do not want. I added the line $ ("# form1") [0] .reset (); to refresh the form and thus have the value of the session printed on the screen, but it is not working.

index.php:

<?php
    @session_start();
    error_reporting(0);
    ?>
  <!doctype html>
  <html>

  <head>
    <meta charset="utf-8">
    <title>input value to php session</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  </head>

  <body>
    <form method="post" id="form1">
      <input type="text" name="field1" id="field1" onblur="run(this)">
    </form>
    <br /><br />
    <?php echo $_SESSION['field1'];?>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script language="javascript">
      function run(sel) {
        var text = $("#field1").val();
        if (text != "") {
          $.ajax({
            type: "POST",
            url: "input.php",
            data: {
              field1: text
            }
          }); //.done(function() {alert(text)});    
        }

        if (done.(function() {
            $("#form1").reset()
          }));
      }
    </script>
  </body>

  </html>

The input.php file:

<?php
  @session_start();
  error_reporting(0);

  if (isset($_POST["field1"])){
    $_SESSION['field1'] = $_POST["field1"]; 
  }
?>
