vue-router中router.push、router.replace、router.go的区别

router.push

想要导航到不同的 URL，则使用 router.push 方法。这个方法会向 history 栈添加一个新的记录，所以，当用户点击浏览器后退按钮时，则回到之前的 URL。

  == 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 功能一样，唯一的不同就是，它不会向 history 添加新记录，只是替换掉当前的 history 记录。

== router.replace(...) == windows.history.replaceState(...)

router.go

这个方法的参数是一个整数，意思是在 history 记录中向前或者后退多少步，类似 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)
