在插入和修改组件时使用相同的形式和功能

Question

问题：

我想在 2 个组件中共享和使用相同的表单。
一个组件用于插入，第二个组件用于修改，因此它在表单中预选了一些值。

是使用服务更好还是使用可重复使用的表单更好？我是 angular 的新手，我在开发中学习。

我该如何处理？

我尝试创建服务，但是当我在服务中创建表单并在组件内创建 patchValue 时，它显示 "cannot read patchValue of undefined"。

但是当我厌倦了顶部控制台记录表单时它没问题，表单被声明和初始化。

这是我的服务和之后插入的组件。

如果可能的话，我想通过服务实现这样的目标：

我强烈建议使用一个包含表单的组件，并根据您所在的 "mode"（"insert" 或 "modify"):

initForm() {
  if (this.mode === 'insert') {
    // initialise empty form
  } else {
    // populate modification form
  }
}

您可以使用路由参数、路由器数据、服务数据……任何您喜欢的方式来设置模式:)

在插入和修改组件时使用相同的形式和功能

Use same form and functions in insert and modify components
