我正在开发一个页面，负责下订单Cart.vue，其中包含两个api调用，handleMail()方法是发送电子邮件并生成订单ID，我正在从网络部分的后端获得响应，如下所示。
{
"message":"order created successfully",
"orderID":87450588
}
我正在捕获该orderID并存储为orderNumber，现在我想将该orderNumber传递给另一个名为orderPlace.vue的组件，并在模板部分中显示该orderNumber。如果我正在创建事件总线，它不起作用，请帮助我将orderNumber传递到另一个组件。。。

如果在执行发射时orderPlace.vue组件未处于活动状态。它无法接收元素。您可以尝试在localStorage中注册您的订单号。或者调用orderPlace.vue作为子组件，并将订单号传递给props
