我正在研究laravel项目，遇到了一项要求。
我必须制作发票页面。
在我们可以选择客户端（列表将从数据库中拉出）和项目（列表将从数据库中拉出）的地方，我们必须输入其他一些详细信息，例如发票编号。在同一页面中，我们应该能够输入多行以输入商品名称，描述，数量，价格，总计和货币。
稍后，我们需要提取所有这些行数据，并根据添加的行数来计算总数。
下面是我的代码。
发票/创建：

jquery-它包含用于添加多行的代码。我们可以单击“添加”按钮，然后将出现一个对话框，以输入项目名称，描述，数量，价格，总计和货币。我正在将这些数据发送到发票创建页面。

此代码不起作用，当我单击“提交”按钮时，什么也没有发生。拜托，有人可以帮我吗？
