Vue.js scroll to top of new page route after setTimeout

由 走远了吗. 提交于 2021-01-20 17:43:27
问题 I have a page transition that doesn't work nicely when the scroll to the top of a new route is instant. I'd like to wait 100ms before it automatically scrolls to the top. The following code doesn't end up scrolling at all. Is there a way to do this? export default new Router({ mode: 'history', routes: [ { path: '/', name: 'Home', component: Home } ], scrollBehavior (to, from, savedPosition) { setTimeout(() => { return { x: 0, y: 0 } }, 100); } }) 回答1: This is natively supported by Vue now,

【前端词典】Vuex 注入 Vue 生命周期的过程

前言 这篇文章是【前端词典】系列文章的第 13 篇文章，接下的 9 篇我会围绕着 Vue 展开，希望这 9 篇文章可以使大家加深对 Vue 的了解。当然这些文章的前提是默认你对 Vue 有一定的基础。如果一点基础都没有，建议先看官方文档。 第一篇文章我会结合 Vue 和 Vuex 的部分源码，来说明 Vuex 注入 Vue 生命周期的过程。 说到源码，其实没有想象的那么难。也和我们平时写业务代码差不多，都是方法的调用。但是源码的调用树会复杂很多。 为何使用 Vuex 使用 Vue 我们就不可避免的会遇到组件间共享的数据或状态。应用的业务代码逐渐复杂，props、事件、事件总线等通信的方式的弊端就会愈发明显。这个时候我们就需要 Vuex 。Vuex 是一个专门为 Vue 设计的状态管理工具。 状态管理是 Vue 组件解耦的重要手段。 它借鉴了 Flux、redux 的基本思想，将状态抽离到全局，形成一个 Store。 Vuex 不限制你的代码结构，但需要遵守一些规则： 应用层级的状态应该集中到单个 store 对象中 提交 mutation 是更改状态的唯一方法，并且这个过程是同步的 异步逻辑都应该封装到 action 里面 Vuex 注入 Vue 生命周期的过程 我们在安装插件的时候，总会像下面一样用 Vue.use() 来载入插件，可是 Vue.use() 做了什么呢？

问题 I'm using Vue router with two pages: let routes = [ { path: '/', component: require('./components/HomeView.vue') }, { path: '/intro', component: require('./components/IntroView.vue') } ] This works fine, except that each of my components has different body styling: HomeView.vue: <template> <p>This is the home page!</p> </template> <script> export default { } </script> <style> body { background: red; } </style> IntroView.vue: <template> <div> <h1>Introduction</h1> </div> </template> <script>

问题 Is there a way to center content vertically in Vuetify? With the text-xs-center helper class, the content gets centered horizontally only: <v-container grid-list-md text-xs-center> <v-layout row wrap> <v-flex xs12> Hello </v-flex> </v-layout> From the API, I tested some other helper classes such as align-content-center but did not achieve the result. 回答1: Update for new vuetify version In v.2.x.x , we can use align and justify. We have below options for setup the horizontal and vertical

How to watch prop even if it does not change?

由 可紊 提交于 2021-01-20 13:35:27
问题 I have watcher with the same name as a prop. The prop is dynamically set in a parent component on some event. I need something that triggers some function in the child component with property value every time the event is triggered on parent -even if the prop it set is the same. Is there any watcher option or other method of handling such case which would allow me to do that ? What I tried (this is in Post component): watch: { replyClicked: { handler(newVal, oldVal) { console.log(newVal,

YYDS: Webpack Plugin开发

  作为一名踏足前端时间不长的小开发必须得聊一聊 webpack ，刚开始接触webpack时第一反应这是啥(⊙_⊙)? 怎么这么复杂，感觉好难呀，算了先不管这些！时间是个好东西呀，随着对 前端工程化 的实践和理解慢慢加深，跟webpack接触越来越多，最终还是被ta折服，不禁高呼一声“ webpack yyds（永远滴神）！ ”   去年年中就想写一些关于webpack的文章，由于各种原因耽搁了（主要是觉得对webpack理解还不够，不敢妄自下笔）；临近年节，时间也有些了，与其 "摸鱼"不如摸摸webpack，整理一些"年货"分享给需要的xdm！后续会继续写一些【 Webpack】系列文章，xdm监督··· 导读   本文主要通过实现一个 cdn优化 的插件 CdnPluginInject 介绍下 webpack 的插件 plugin 开发的具体流程，中间会涉及到 html-webpack-plugin 插件的使用、 vue/cli3+ 项目中webpack插件的配置以及webpack相关知识点的说明。全文大概2800+字，预计耗时5~10分钟，希望xdm看完有所学、有所思、有所输出！ 注意： 文章中实例基于 vue/cli3+ 工程展开！ 一、cdn常规使用 index.html: <head> ··· </head> <body> <div id="app"></div>
