【推荐阅读】微服务还能火多久?>>> 前言 上一篇讲了使用webpack初始化构建vue项目, 那么这一篇接着上一篇的内容继续讲一下,element的引入, axios请求载入, router路由载入和vuex状态管理 一.公用样式初始化重置 在讲公用样式初始化重置之前, 首先需要知道为什么要样式重置. 为了兼容性考虑,每个浏览器默认样式不一样,比如行高,某个浏览器是1,另外zd一个浏览器可能是1.1,再有一个浏览器可能就是0.9,这样在开发网页写样式表的时候,处理起来回比较麻烦,所以直接给重答置统一,这样就能很方便的处理兼容性。 所以, 通常我们在开发项目时, 都会在如前文中的style->common.js中进行一些样式重置.来保证后续开发中一些不必要的影响. 样式重置代码就不写了, 有很多, 如 body, dl, dd, h1, h2, h3, h4, h5, h6, p, form{ margin : 0 ;} ol,ul{ margin : 0 ; padding: 0 ;} a:focus, a :active { outline : none; } a, a :focus, a :hover { cursor : pointer; color: inherit; text-decoration: none; } 复制代码 二.Element的引入

Vuex - Run function after multiple dispatches

问题 I'm creating an application and at a certain point I need to load some data, but for the user not to see broken data I'm inserting a loading component. Currently I put a setTimeout in the load, but at some point the API response can take more than 1 second. So I would like to update the loading state only when all the dispatches become completed. MainComponent.vue beforeCreate() { this.$store.dispatch('responsibles/fetchData') this.$store.dispatch('events/fetchData') this.$store.dispatch(

vuex2.0 关于 状态管理state getter mutation 和action

Vuex 状态管理 1 State 三种状态用法 A.直接获取Store中的State 属性的值 Computed:{ // 计算属性 Count (){ Return This.$Store.State.Count } } b.直接从mapState中获取 computed:{ ...mapState(['count']) <===> 等同上面的直接获取store中state中的属性值 } c.在mapState中定义别名 computed:{ ...mapState({ count:(state) = state.count }) } 以上三种都可以获取当前state中对应的参数值 注意在引用之前我们必须需要引入 import {mapState,mapGetters,mapMutations} from 'vuex' 2 getter 获取计算后的state 属性的值 // getter 只是针对的是state里面的参数 列如 从store的getters中获取到firstNmme 和 lastName 属性 在getter中展示 fullName (state) { return `${state.firstName}+${state.lastName}` } computed :{ fullName () { return this.$store.getters

vuex是一个专门为vue.js设计的状态管理模式,并且也可以使用devtools进行调试。 下面给大家来贴一下我的vuex的结构 下面是store文件夹下的state.js和index.js内容 //state.js const state = { headerBgOpacity:0, loginStatus:0, count:66 } export default state //index.js import Vue from 'vue' import Vuex from 'vuex' import state from './state' import actions from './actions' import getters from './getters' import mutations from './mutations' Vue.use(Vuex) export default new Vuex.Store({ state, actions, getters, mutations }) 前端全栈学习交流圈:866109386,面向1-3经验年前端开发人员,帮助突破技术瓶颈,提升思维能力,群内有大量PDF可供自取,更有干货实战项目视频进群免费领取。 下面开始在test.vue组件当中使用vuex的state状态对象 方式一 <template> <div
