Javascript React.js-在我的项目中创建新发票时遇到问题

Javascript React.js-在我的项目中创建新发票时遇到问题,javascript,reactjs,react-state,Javascript,Reactjs,React State,我是一个新的反应者,我真的可以用手去理解如何在我的项目中创建一个新的发票 问题: 目前,我可以创建一个新的发票没有问题,如下图所示。我将输入更改为一些测试数据,以帮助说明我遇到的问题 下面是显示到目前为止堆栈中发票总数的俯视图 当我创建第二张新发票时,问题就出现了。它保留了我第一次修改的所有旧数据,即使我可以单击它们并彼此独立地修改它们。奇怪的是。。。只有一些价值观保持不变,而其他价值观可以相互独立 这是在创建第二张发票之后直接进行的: 我将第二张发票更改为所有新数据: 这是发票1中的

我是一个新的反应者,我真的可以用手去理解如何在我的项目中创建一个新的发票

问题: 目前,我可以创建一个新的发票没有问题,如下图所示。我将输入更改为一些测试数据,以帮助说明我遇到的问题

下面是显示到目前为止堆栈中发票总数的俯视图

当我创建第二张新发票时,问题就出现了。它保留了我第一次修改的所有旧数据,即使我可以单击它们并彼此独立地修改它们。奇怪的是。。。只有一些价值观保持不变,而其他价值观可以相互独立

这是在创建第二张发票之后直接进行的:

我将第二张发票更改为所有新数据:

这是发票1中的结果:

现在,当我创建第三张新发票时:

这告诉我他们是有联系的。。与我的项目的直接链接如下:

否则,我认为问题在于如何创建新发票或如何修改发票中的数据。请看我修改发票的第113行或创建新发票的第94行。我需要所有能得到的帮助,谢谢
