Vue.js

问题 A quote from the vue official documentation states that $refs...are not reactive. However, I have used such refs in templates and they are indeed reactive, and even in methods, computed props, and watchers (as long as you access it after being mounted). Several third party vue libraries e.g. this one also provides features that use/depend on the reactivity of refs. Can someone please clarify what the official doc meant by refs not being reactive please? 回答1: You are misunderstanding what it

问题 I am creating a new project using nuxt.js v2.3.0. When i run npm run dev in my idea console everything compiles correctly but when I go to the page I get the following error: Nuxt.js + Vue.js is detected on this page.

问题 In my Vue app, a user's homepage depends on their role. To ensure that a user is shown the correct homepage, I use this navigation guard: export default (to, from, next) => { const authService = getAuthService() if (to.path === '/') { // if they've requested the home page, send them to // different pages depending on their role if (authService.isUser()) { next({ name: 'events' }) } else if (authService.isAdmin()) { next({ name: 'admin-events' }) } else { next() } } } Then when a user

问题 Is there a possibility in Vue to deal with incoming events inside one function in a way similar to this? <template> <component v-on="eventsDistributor(eventName, $event)"/> </template> <script> export default { props: { handlers: Object, }, methods : { eventsDistributor (name, $event) { let handler = this.handlers[name] if (handler) return handler($event) } } } </script> 回答1: I think $listeners might be what you need. It's an object that contains all parent listeners, and it could be

问题 I'm learning Vue.js and I'm struggling to find a way to organize my code. I'm trying to make everything as modular as possible, so when making a slider i did the following: <template> <div class="banners"> <slot></slot> </div> </template> <script> export default { methods: { echo() { console.log('Echoing..') } }, mounted() { $('.banners').slick(); } } </script> And in my view I simply use the component: <banners> <?php for ($i = 0; $i < 5; $i++) : ?> <img src="http://lorempixel.com/1440/500"

问题 Is there a way to find how much size a state (object, array, etc) or a component occupies in memory. In my current context, I need that to know if a specific state/component is very heavy (in term of memory). In chrome, I already tried to snapshot the memory, but I couldn't find how to identify a specific component or state in the result in such large info like this: 来源： https://stackoverflow.com/questions/55476617/how-to-know-a-vuex-state-or-a-component-size-in-memory
