问题 Is there any way to route by a query param? I would like to match the following route: site.com/?foo=123 . I've tried things like { path: '/\?foo=[\d]*' } without success. 回答1: Unfortunately, you can't match a query param in the path string of a route definition. Vue Router uses path-to-regexp , and its documentation says: The RegExp returned by path-to-regexp is intended for use with pathnames or hostnames. It can not handle the query strings or fragments of a URL. You can use regular

Computed property reactive to window.innerwidth in VueJS

阅读更多关于 Computed property reactive to window.innerwidth in VueJS

问题 Basically, what I need is a computed property that returns true when the window.innerwidth is equal or lower than 768px and false when it's higher than 768px. What I did: computed: { isMobile() { if (window.innerWidth <= 768) { return true } return false } } But that computes that property only once, and if I resize the window later, it doesn't react to that change. What can I do? 回答1: Add an eventlistener to the window like so: new Vue({ el: "#app", data() { return { windowWidth: window

Binding method result to v-model with Vue.js

阅读更多关于 Binding method result to v-model with Vue.js

问题 How do you bind a method result to a v-model with Vue.js? example : <someTag v-model="method_name(data_attribute)"></someTag> I can't make it work for some reason. Thank you. 回答1: v-model expressions must have a get and set function.
