使用Ajax Jquery删除Zend中的Item

Question

当我按下删除按钮时，我想删除一行用户表。但它的错误

deleteAction中的代码

public function deleteAction(){
    $this->view->Title = 'Member :: Group manager :: Delete';
    $this->view->headTitle($this->view->Title,true);
    $tblGroup = new Default_Model_UserGroup();
    $tblGroup->deleteItem($this->_arrParam,array('task'=>'admin-delete'));
    $this->_redirect($this->_actionMain);
}

文件jquery中的代码

    function DeleteGroup(element,id) {
jConfirm('Are you sure you want to delete this Group?', 'Delete Group', function(r) { if (r)
$.ajax({
  type: "GET",
  url: "<?= $this->baseUrl($this->currentController. '/delete/id')?>" + id,
  data: '',
  success: function(response){
    $(element).parents('tr').remove();
    $.jGrowl('Group deleted');
  }
});
});
}
