检测Vue-Router导航卫士中的返回按钮 [英] Detect Back Button in Navigation Guards of Vue-Router

问题描述

路线如何改变，对我来说很重要.因此，我想通过浏览器或 gsm 的后退按钮更改路线.

How the route is changed, matters for my case. So, I want to catch when the route is changed by a back button of browser or gsm.

这就是我所拥有的:

router.beforeEach((to, from, next) => {
  if ( /* IsItABackButton && */ from.meta.someLogica) {
    next(false) 
    return ''
  }
  next()
})

是否有一些我可以使用的内置解决方案来代替 IsItABackButton 注释?我猜 Vue-router 本身没有，但任何解决方法也可以在这里工作.或者还有其他更喜欢的识别方式吗?

Is there some built-in solutions that I can use instead of IsItABackButton comment? Vue-router itself hasn't I guess but any workaround could also work here. Or would there be another way preferred to recognize it?

推荐答案

这是我找到的唯一方法:

This is the only way that I've found:

我们可以监听 popstate，将其保存在一个变量中，然后检查该变量

We can listen for popstate, save it in a variable, and then check that variable

// This listener will execute before router.beforeEach only if registered
// before vue-router is registered with Vue.use(VueRouter)

window.popStateDetected = false
window.addEventListener('popstate', () => {
  window.popStateDetected = true
})


router.beforeEach((to, from, next) => {
  const IsItABackButton = window.popStateDetected
  window.popStateDetected = false
  if (IsItABackButton && from.meta.someLogica) {
    next(false) 
    return ''
  }
  next()
})
