问题 I have a store in Vuex with an empty state const state = { data: { } }; And a simple mutations for test to change value or add new data const mutations = { changeOrAdd(state, {key,value}) { state.data[key] = value; } }; If I do a commit to changeOrAdd , it is added to state BUT it doesn't have reactivity. I did a simple trick to change a default value const state = { data: { change: 0 } }; And in the mutation: const mutations = { changeValueAttr(state, { key, value }) { state.data[key] =

问题 This follows on from my previous question : How to get states from a Vuex store from within a Vuetify list, VueJs I understand how to get states from the store, but I am struggling commiting mutations from within a list.

总结 写法 import Vue from 'vue' import Vuex from 'vuex' import axios from 'axios' Vue . use ( Vuex ) const store = new Vuex . Store ( { state : { // 购物车数据 shopCart : [ { name : '卫龙大辣条' , price : '¥1.25' } , { name : '鱼豆腐' , price : '¥2' } ] } , getters : { } , mutations : { // 改变购物车数据的函数 // 第一个参数 state就是 Store中的state 第二个参数是执行函数是 用户传递的数据 第三用来判断是否清空购物车 如果是true则清空购物车 handleShopCart ( state , data ) { state . shopCart = data } } , actions : { buyNow ( { commit , state } ) { return new Promise ( ( resolve , reject ) => { axios . get ( '购买按钮对应的请求地址' ) . then ( res => { commit ( 'handleShopCart' , [ ] )

Vuex how to handle api error notification?

时光总嘲笑我的痴心妄想 提交于 2020-01-15 07:33:47
问题 I started working with Vuex 2 weeks ago and I realized that Vuex is very good to handle the state of the app. But, it is difficult to handle the error of API calls. When I get data from the server, I dispatch an action. When data is successfully returned, of course, everything is fine. But when an error happens, I change state, I don't know how to detect it through the state from Vuejs components to notify to the user. Could anyone give me some advice? 回答1: I typically have the following

前言 日常积累,欢迎指正 1、状态管理之 redux、dva、vuex 1.1、redux Redux is a predictable state container for JavaScript apps - Redux是一个可预测的 JavaScript 应用程序状态容器 redux 中 dispatch(action/actionCreator) 触发 state 修改 state 修改引发页面重新渲染 异步处理:借助 redux-saga 等工具实现 container 组件示例 import App from '../pages/App' import { connect } from 'react-redux' import { Dispatch } from 'redux' import { IStoreState } from '../types/todoList' import { willToDone , doneToWill , del , add } from '../actions/todoList' interface IProps { } const mapStateToProps = ( state : IStoreState , ownProps : IProps ) => { return { todoList : state .

How to setup a centralized state for a mapbox map in Vuex?

青春壹個敷衍的年華 提交于 2020-01-13 09:36:06
问题 I just started using vuex with vue. I do (roughly) understand the docs. I have a specific issue for which I am not sure whether I should use vuex and if so how to go about. I have an app in which mapbox map(s) are omnipresent in various layouts and components etc. As I will be making several vue single file components but are working with one same instance of a mapbox map I think it makes sense to have the mapbox map initiated and managed in the vuex store. So e.g. when I change the map

Managing State for Overlay Dismissed Components in Vuetify

问题 I'm building out a vuetify/nuxt frontend for the first time, and I've moved my v-navigation-drawer component out of the default.vue layout, and into it's own component, so that it can be reused in multiple layouts. The activator for this drawer still remains in the default.vue component, so I added a sidebar state to vuex: export const state = () => ({ baseurl: 'http://example.com/api/', sidebar: false, authenticated: false, token: null, user: null, }) The mutator for the sidebar looks like

如图: 1、我们把公用的数据放到一个公共的存储空间存储,然后某一个组件改变了这个公共的数据其他的组件就能感知到。这就是vuex设计理念。我们通常叫它store 2、store包括几个本分   state:存放了所有的公用数据 ,组件想用公用数据 直接调用就ok。   组件如果想要给变公共数据 必须先调用Actions 然后做一些异步处理;Actions再去调用Mutations,只用通过Mutations最终才可以改变公用数据的值。   当然有时候可以略过Actions 让组件直接调用Mutations修改公用数据。 3、组件通过Dispatch方法调用Actions;Actions调用Mutations或者组件调用Mutations的时候用Commit方法。 vuex是一个单项的改变是数据的流程。 来源: https://www.cnblogs.com/xuwupiaomiao/p/12184628.html

Vuex入门简单示例(四)

前言 我想写一系列关于Vuex的入门文章,我是看着vuex官网文档,结合自己从零搭建的vue项目来实践vuex的知识。 Vuex入门系列: Vuex入门简单示例(一) Vuex入门简单示例(二) Vuex入门简单示例(三) Vuex入门简单示例(四) Vuex入门简单示例(五) 本文涉及知识点: vuex之action vuex之mapActions vuex官网描述 在mutation中混合异步调用会导致你的程序很难调试。例如当你调用了两个包含异步回调的mutation来改变状态,你怎么知道什么时候回调和哪个先回调呢?这就是为什么我们要区分这两个概念。在Vuex中,mutation都是同步事务。为了处理异步操作,让我们来看一看Action. Action类似于Mutation,不同在于: Action提交的是mutation,而不是直接变更状态 Action可以包含任意异步操作 让我们在store.js里来注册一个简单的action src/store.js const store = new Vuex.Store({ state: { // ... }, getters: { // ... }, mutations: { // ... }, actions: { changeLogin (context) { context.commit('changeLogin') },
