router.push

想要導航到不同的 URL，則使用 router.push 方法。這個方法會向 history 棧新增一個新的記錄，所以，當用戶點選瀏覽器後退按鈕時，則回到之前的 URL。

<router-link :to="...">  == router.push(...)  == window.history.pushState(...)

// literal string path
router.push('home')

// object
router.push({ path: 'home' })

// named route
router.push({ name: 'user', params: { userId: 123 }})

// with query, resulting in /register?plan=private
router.push({ path: 'register', query: { plan: 'private' }})
 

const userId = 123
router.push({ name: 'user', params: { userId }}) // -> /user/123
router.push({ path: `/user/${userId}` }) // -> /user/123
// This will NOT work
router.push({ path: '/user', params: { userId }}) // -> /user

router.replace

跟 router.push 功能一樣，唯一的不同就是，它不會向 history 新增新記錄，只是替換掉當前的 history 記錄。

<router-link :to="..." replace> == router.replace(...) == windows.history.replaceState(...)

router.go

這個方法的引數是一個整數，意思是在 history 記錄中向前或者後退多少步，類似 window.history.go(n)

 router.go(...)  == windows.history.go

// go forward by one record, the same as history.forward()
router.go(1)

// go back by one record, the same as history.back()
router.go(-1)

// go forward by 3 records
router.go(3)

// fails silently if there aren't that many records.
router.go(-100)
router.go(100)
