Gudday 伙计们，在使用 jquery 的方法远程加载表单后，我在将表单成功发布到数据库后遇到了一点挑战load()，它在 google chrome 中工作，但在使用 firefox 时不工作。感谢您的帮助。

PHP 代码。

<?php
        include 'login.php';
  if( isset($_POST['c_title']) && isset($_POST['c_code']) && isset($_POST['staff_id'])&& isset($_POST['staff_fulname'])
  && isset($_POST['c_desc'])&& isset($_POST['unit']) ){

      $c_title = sanitize_string($_POST['c_title']);
      $c_code = sanitize_string($_POST['c_code']); 
      $staff_id = sanitize_string($_POST['staff_id']);
      $staff_fulname= sanitize_string($_POST['staff_fulname']); 
      $c_desc = sanitize_string($_POST['c_desc']);
      $unit = sanitize_string($_POST['unit']); 



      $sql = " insert into course values('$c_title','$c_code','$staff_id','$staff_fulname','$c_desc','$unit') ";

      $result = mysql_query($sql);

      if($result){
        // echo '<br/> <div align="center"><small class="alert alert-success">&radic; Saved Successfully!</small></div>';
        echo '<script>alert("Saved Successfully!");</script>';
      }
      else{
          echo '<script>alert("Error Occured!");</script>';
      }



  }

   function sanitize_string($var){
    $var = mysql_real_escape_string($var);
    $var = htmlentities($var);
    $var = stripslashes($var);

    return $var;
   }
  ?>
