问题 How can I fix this error in Nuxt? A tip would be appreciated, I've been trying to get this to work for a few hours. [Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside <p>, or missing <tbody>. Bailing hydration and performing full client-side render.

Need multiple instances of Vuex module for multiple Vue instances

由 十年热恋 提交于 2021-02-08 10:30:47
问题 I'm integrating Vue onto a site for forms, which means I have to create several instances of that Vue application if there are multiple forms on the page. All instances share the same Vuex store. I created a Vuex module so that each Vue instance could have it's own local state. My main goal is to prevent one Vue instance from updating the state of another Vue instance. Here's my Vuex module export default { state() { return { stateObj: {...} } } } Creating my Vuex instance: export default new

Vuex computed properties only work with getters

由 杀马特。学长 韩版系。学妹 提交于 2021-02-07 19:25:32
问题 When I put this in my Vue component ... // using store getter computed: { authenticated() { return this.$store.getters.authenticated } } ... it works. The value for authenticated is reactive and the computed property returns true when the value in the vuex store is true . This should work ... (and would be the right way according to the docs) // using store state computed: { authenticated() { return this.$store.state.authenticated } } ... but doesn't. The computed property is always false .

How do I warn a user of unsaved changes before leaving a page in Vue

由 余生长醉 提交于 2021-02-05 20:21:13
问题 I have an UnsavedChangesModal as a component that needs to be launched when the user tries to leave the page when he has unsaved changes in the input fields (I have three input fields in the page). components: { UnsavedChangesModal }, mounted() { window.onbeforeunload = ''; }, methods: { alertChanges() { } } 回答1: Assuming you're using vue-router (and you probably should be), then you'll want to use the beforeRouteLeave guard. The documentation even gives an example of this exact situation:

一 前沿简介 如何一步步构建自己的数据库平台 二 技术介绍 后端语言 python 后端框架 django-rest-framework 前端动态 vue+vuex+axios 前端ui element ui 前端ui框架 vue-admin 三 开发工具 我推荐pycharm 很经典的开发IDE工具,可以同时进行drf和vue框架开发 四 前后端分离框架 优点 现在流行的python框架都已经在遵循前后端分离策略,这样能更好的让前端研发帮你拓展功能 能降低学习成本,更好的分离业务逻辑 缺点 任何关于安全或者逻辑的判断可能都需要前后端都做,防止出现安全问题,我列了以下几点 1 认证登录 2 权限菜单 3 传递数据的有效值判定等 五 开发流程 1 后端python构建 api接口 2 采用postman测试api接口调用 3 前端vue构建 4 前后端进行数据交互 六 关键点注意 1 在开发一个功能模块前一定要设计完整的流程,比如数据库查询模块,考虑各种情况和限制,设计出完善的功能流程,在后期能避免开发的低效率问题 2 前后端数据交互制定一个标准的数据格式,通用在各个功能模块,形成统一的标准 3 项目前期以实现功能项目为主,不要怕代码繁琐重复,后期经验丰富了再来精简代码,封装模块组件 4 多多和研发人员和其他同行进行交流,参与平台测试.不断的改进功能设计,能帮你构建一个更加健壮的平台

Checking auth token valid before route enter in Vue router

由 那年仲夏 提交于 2021-02-04 10:46:20
问题 I have a simple use case, where my application is using vue-router and vuex . Then store contains a user object which is null in the beginning. After the user is validated from the server it sends back an user object which contains a JWT auth token which is assigned to the user object in the store. Now lets assume that the user came back after 3 hours and tried to visit a route or perform any other action, considering that the auth token has expired by then, what would be the best way to
