使用Vuex优化前面的Todos 基本要点与基本流程 //TodoHeader this . $store . dispatch ( 'addTodo' , todo ) //actions addTodo ( { commit } , todo ) { // 提交一个comutation请求 commit ( ADD_TODO , { todo } ) // 传递给mutation的是一个包含数据的对象 } , //mutations [ ADD_TODO ] ( state , { todo } ) { // 方法名不是ADD_TODO, 而是add_todo state . todos . unshift ( todo ) } , 一旦要读vuex管理的状态或者计算属性都用computed 一般的串变成变量用中括号：[ADD_TODO] 强调多组件状态管理，一个组件用的就不用vuex了对于get set 就要单独写,注意在getters中不要用this，传一个getters去获取当前模块的方法 < input type = "checkbox" v - model = "checkAll" / > checkAll : { get ( ) { // 决定是否勾选 return this . $store . getters . isAllSelect } , set (

When to use the base Vue instance, Vuex or mixin?

阅读更多关于 When to use the base Vue instance, Vuex or mixin?

问题 In Vue, you can store commonly used variables and methods in the base Vue instance. This way other components can access this data. new Vue({ data: { name: 'John' } }); If you are using Vuex for state management you could also store this data here as well. const store = new Vuex.Store({ state: { name: 'John' } } From my understanding, Vue mixins also offer the same functionality (allowing any component to access this commonly shared data globally). Vue.mixin({ data() { return { name: 'John' }
