Question

我正在使用Zend Framework，为了说明工作原理，我在这篇文章中添加了saveAction（），它完美无瑕。它将根据需要制作动画并更改课程。上传函数只改变文本并忽略javascript。我可以做有效的警报，但jquery是不可能的。我得到错误，说$是未定义的。怎么可能在1个案例中没有被定义而不是另一个？

我正在使用ajax捕获上传表单，然后将其放入#savecontainer。

希望有一个解决方案，它似乎是一个小问题，但我自己找不到它。谢谢。

它看起来像这样：

$(document).ready(function() {
  $('#newsForm').ajaxForm({
    target: '#savecontainer'
  });
  $('#uploadForm').ajaxForm({
    target: '#savecontainer'
  });
  $("#btn_save").click(function () {
    $('#newsForm').submit();
  });
  $("#btn_upload").click(function () {
    $('#uploadForm').submit();
  });
});


public function saveAction()
{ 
  $this->_helper->layout->disableLayout();
  $db = new Admin_Model_DbAccess();
  if(isset($_POST['active']))
    $_POST['active'] = 1;
  else 
    $_POST['active'] = 0;

  if($_POST['id'] == 0){
    // If it is a new post

    $data = array(
      'header' => $_POST['header'],
      'message' => $_POST['message'],
      'date' => time(),
      'user' => Zend_Auth::getInstance()->getStorage()->read()->id,
      'image' => $_POST['image'],
      'active' => $_POST['active'],
      'category' => $_POST['category']
    );
    if($db->addNews($data)){
      // set the css variables to saved
      echo "<script type='text/javascript'>
        $('#savecontainer').fadeOut(200).attr('class', 'savecontainer_success').fadeIn(400);
        $('#news_id').attr('value', '".$db->lastInsertId()."');
    $('#upload_box').show('slide', {direction: 'up'}, 500);
    $('#news_id_upload').attr('value', '".$db->lastInsertId()."');
      </script>";
      echo "Status: Added.";
    }else{
      // set the css variables to failed
      echo "<script type='text/javascript'>
        $('#savecontainer').fadeOut(200).attr('class', 'savecontainer_fail').fadeIn(400);

      echo "Status: Error.";
    }

      echo "<script type='text/javascript'>
        $('#savecontainer').fadeOut(200).attr('class', 'savecontainer_success').fadeIn(400);

      echo "<script type='text/javascript'>
        $('#savecontainer').fadeOut(200).attr('class', 'savecontainer_fail').fadeIn(400);
      </script>";
      echo "Status: Error.";
    }
  }
}
public function uploadAction(){

为什么不使用ajax调用而不是.submit？并在PHP代码中，从函数中删除js记录并返回数据（数组或ojbect），并使用返回该数据的回调函数在js脚本中处理它

使用ajax和.attr（'class'，'new_class'）时jQuery问题
