jquery ajax中的Laravel 5令牌不匹配异常

我正在用Laravel 5和Jquery ajax开发一个应用程序。我在视图中有一个选项卡面板。它在单击选项卡按钮时加载一个初始表单。它使用Jquery ejax加载，没有任何问题。之后，用户可以在表单中输入数据，然后单击更新按钮，数据应该使用jQueryAjax保存到数据库中。基本上没有页面刷新

虽然以前的ajax表单加载工作正常，但当单击此按钮时，页面刷新并显示令牌不匹配异常。我也包含了csrf令牌。我不知道原因是什么。我已将csrf令牌作为元内容值包含，如下所示

<meta name="csrf-token" content="{{csrf_token()}}" />

以下是Laravel堆栈跟踪

php artisan clear已编译

通过访问ajax请求中的{{csrf_token（）}}，将csrf_令牌嵌入请求。

您可以发布ajax Post代码吗？有时缺少一些代码行会导致此错误。实际上，我的另一个用于配置文件信息加载的ajax代码工作正常。因此，我复制了相同的代码，并根据此要求对其进行了编辑。无论如何，我将在此处发布代码。您可以发布您的ajax发布代码吗？有时缺少一些代码行会导致此错误。实际上，我的另一个用于加载配置文件信息的ajax代码工作正常。因此，我复制了相同的代码，并根据此要求进行了编辑。无论如何，我将在此处发布代码。感谢您提供的代码。但我以前尝试过此代码，但没有成功。对于此代码，即使是第一个表单也没有加载。感谢您提供的代码。但是我以前尝试过这个方法，但没有效果。对于此代码，即使是第一个表单也没有加载。
