如何正确传递参数给vuex mapActions

Question

我有一个 ProjectPage.vue 页面显示 v-data-table 中的问题。项目从侧边栏中的服务器 api 调用中检索并显示在那里。选择一个项目后，我想使用该项目的 id 从服务器获取它的问题。是否可以使用 Vuex 来实现。
是否可以使用 Vuex，每个项目都可以使用相同的 .js 文件来检索其问题，因为可能有任意数量的项目。

我想做的是从 VerticalNavMenu.vue 开始，将 id 和项目作为道具传递给 ProjectPage，这样我就可以将 id 作为参数传递给 ProjectPage 中的 mapAction 以检索其问题。

我现在的方法不起作用。当我打开项目的 table

时 table 没有可用数据

我希望 Peoject_Pages.js 帮助理解我的问题。

Answer 1

有两种方法可以解决您的问题。

或者您在 fetchProjectIssueList 方法中传递一个带有键 projectid 的对象
或者你不需要在fetchProjectIssueList方法中解构对象

this.fetchProjectIssueList({ projectid: this.id })
...
async fetchProjectIssueList({ commit }, {projectid}) { ... }

或

this.fetchProjectIssueList(this.id)
...
async fetchProjectIssueList({ commit }, projectid) { ... }
