我的原因是因为:在上级组件和下级组件都使用useStore()获取store // store.tsimport{InjectionKey}from'vue'import{createStore,useStoreasbaseUseStore,Store}from'vuex'import{app,AppState}from'./modules/app'// 为 store state 声明类型exportinterfaceState{app:AppState}// 定义 injection keyexportconstkey:Inj...

env.NODE_ENV !== 'production') { warn(`Injection "${key}" not found`, vm) } } } return result } } 可以看到,如果是from的注入方式,则使用 while 循环一级级找父节点,然后从父节点的_provided里面得到这个inject属性的值;如果是default的注入方式,则直接赋值即可。

结论先行:Vuex原理可以拆解为三个关键点。第一点、其实就是每个组件实例里都注入了Store实例。第二点、Store实例中的各种方法都是为Store中的属性服务的。第三点、Store中的属性变更触发视图更新。
The third point is that the attribute change inStore This article mainly explains the first point. The second point is in my last article,learning the overall architecture of vuex source code, and creating your own state management library. I will not go into details in this article. The thi...

You can still do the injection in setup and then check the result in the hook. No need for any new API. setup() { const prefersDarMode = inject('darkModeCheck') onMounted(() => { // assuming you provided a ref. if (prefersDarkMode.value === true) { // do something } }) }...
