vue Router4.0如何重置matcher
时间: 2023-12-10 11:03:23 浏览: 113
在 Vue Router 4.0 中,可以通过调用 `router.matcher = newRouter.matcher` 来重置 matcher。具体步骤如下:
1. 首先,需要在 Vue Router 实例化的时候保留一个对该实例的引用,例如:
```
const router = createRouter({
// ...
})
```
2. 然后,当需要重置 matcher 时,可以创建一个新的 Vue Router 实例,并将其 matcher 赋值给原始实例的 matcher,例如:
```
const newRouter = createRouter({
// ...
})
router.matcher = newRouter.matcher
```
这样,原始实例的 matcher 就被重置了。注意,这里只是重置了 matcher,而不会重新创建一个全新的 Vue Router 实例。

vue3 router.matcher
根据提供的引用内容,Vue Router 中的 matcher 是一个用于匹配路由的核心模块。在 Vue Router 中,所有的 Route 最终都会通过 createRoute 函数创建,并且它最后是不可以被外部修改的。而 matcher 则是用于创建和管理这些 Route 的。在 Vue3 中,matcher 仍然是 Vue Router 的核心模块,但是它的实现方式可能会有所不同。具体的实现方式需要查看 Vue3 的官方文档或者源码。
router.matcher
`router.matcher` is a method in Vue Router that returns a function used to match a given location against the routes defined in the router. It takes a single parameter, which is the location object to be matched.
The returned function has the following signature:
```javascript
function (location: Location, currentRoute?: Route, redirectedFrom?: Location): Route | undefined
```
The `location` parameter is the location object to be matched. The `currentRoute` parameter is an optional current route object, which can be used to help with nested routes. The `redirectedFrom` parameter is an optional location object that represents the original location before any redirects were applied.
The function returns a `Route` object if there is a match, or `undefined` if there is no match.
Here is an example of how to use `router.matcher`:
```javascript
import { createRouter, createWebHistory } from 'vue-router'
const router = createRouter({
history: createWebHistory(),
routes: [
{ path: '/', component: Home },
{ path: '/about', component: About },
{ path: '/contact', component: Contact }
]
})
const location = { path: '/about' }
const matchedRoute = router.matcher(location)
console.log(matchedRoute) // Route { path: '/about', component: About }
```
