Vuex的API文档

由 我的未来我决定 提交于 2019-12-25 18:26:41
前面的话 　　本文将详细介绍Vuex的API文档 概述 import Vuex from 'vuex' const store = new Vuex.Store({ ...options }) 【构造器选项】 state 类型: Object 　　Vuex store 实例的根 state 对象 mutations 类型: { [type: string]: Function } 　　在 store 上注册 mutation，处理函数总是接受 state 作为第一个参数（如果定义在模块中，则为模块的局部状态）， payload 作为第二个参数（可选） actions 类型: { [type: string]: Function } 　　在 store 上注册 action。处理函数接受一个 context 对象，包含以下属性： { state, // 等同于 store.state, 若在模块中则为局部状态 rootState, // 等同于 store.state, 只存在于模块中 commit, // 等同于 store.commit dispatch, // 等同于 store.dispatch getters // 等同于 store.getters } getters 类型: { [key: string]: Function } 　　在 store 上注册 getter

vuex 使用详解

vuex 使用详解 一、什么是vuex vuex是一个专门为vue.js设计的集中式状态管理架构。它采用集中式存储管理应用的所有组件的状态，并以相应的规则保证状态以一种可预测的方式发生变化。。 二、vuex使用场景 vuex主要是是做数据交互，父子组件传值可以很容易办到，但是兄弟组件间传值（兄弟组件下又有父子组件），或者大型spa单页面框架项目，页面多并且一层嵌套一层的传值，异常麻烦，用vuex来维护共有的状态或数据会更便捷 场景说明： 由于vuex中的state存放的数据在页面刷新时会丢失，vuex只能用于单个页面中不同组件（例如兄弟组件）的数据流通 三、Vuex核心概念 1、store：类似容器，包含应用的大部分状态 一个页面只能有一个容器 状态存储是响应式的 不能直接改变store中的状态，唯一途径显示地提交mutations 在actions里面，也不能直接更改state里面的状态值，必须先定义一个mutations，然后在actions里面commit这个mutations，从而来更改state的状态值； 如果要再次请求异步，那么就是dispatch一个actions 2、State：包含所有应用级别状态的对象 3、Getters：在组件内部获取store中状态的函数，类似组件的计算属性computed 4、Mutations：唯一修改状态的事件回调函数，默认是同步的

How to design a store in Vuex to handle clicks in nested, custom components?

由 大城市里の小女人 提交于 2019-12-25 04:11:55
问题 I'm trying to design a store to manage the events of my Vuex application. This far, I have the following. import Vue from "vue"; import Vuex from "vuex"; Vue.use(Vuex); const state = { dataRows: [], activeDataRow: {} }; const mutations = { UPDATE_DATA(state, data) { state.dataRows = data; state.activeDataRow = {}; }, }; export default new Vuex.Store({ state, mutations }); I'm going to have a number of list items that are supposed to change the value of the data in the store when clicked.

How to modify deep vuex data with v-model

由 眉间皱痕 提交于 2019-12-25 03:24:15
问题 I'm trying to modify a vuex store, but using v-model on a key deep inside the object. Obviously when modifying data it must be done using mutations. But i'm struggling to figure out how to do this with a deep value. Here's a fiddle, which should generate a vuex error (the error isn't generated in the fiddle for some reason): [vuex] Do not mutate vuex store state outside mutation handlers https://jsfiddle.net/antony_publica/L27pcksn/70/ How can I setup a computed value for an object thats

Subfolder in the Nuxt store is messing with the modules

问题 Trying to create a project in Nuxt and typescript. However the documentation it's very poor and I hit a lot of issues. Somehow was able to solve most of them, but stacked on an issue with the store . Based on the Nuxt documentation every file inside the store directory is transformed to a module. To organize better my project I decided to add a subfolder inside store folder. However after this change my components are having issues with calling Mutation , Action and getting values from the

Error in render function: “TypeError: Cannot read property of undefined”, using Vuex and Vue Router

问题 I have been dealing with an issue using Vue, Vuex and Vue-Router. I'm building a flash cards app, fetching all the cards on main app creation, then using a Vuex getter to get each card by its id which is passed as a route parameter. Relevant bits: App.vue export default { components: { 'app-header': header, }, data() { return { } }, created() { this.$store.dispatch('getAllCards'); } } The dispatch('getAllCards') is just pulling all the cards from the DB and committing to Vuex store.js . Now I

Why is this Vue computed property not reactive?

由 ☆樱花仙子☆ 提交于 2019-12-24 19:33:56
问题 I'd like my view, using an id passed as a prop, to lookup an object's property in the store. The object in the store appears asynchronously, so the object might not be present right away. I'd like the view to react to the object's eventual appearance. <template> <div> <h1>{{ title }}</h1> </div> </template> <script> export default { props: ['id'], computed: { widget () { let path = `widget/${this.id}` return this.$store.state.widgets[path] }, title () { let widget = this.widget return (widget
