关于Vue, mixin全局混入destory,一个Vue实例的destory生命周期被多次执行

# mixin.js

export default {
  install (Vue) {
    Vue.mixin({
      mounted () {
          if (window.history && window.history.pushState) {
            history.pushState(null, null, document.URL)
            window.addEventListener('popstate', this.funBack, false)
          }
      },
      destroyed () {
          let currentRt = this.$router.currentRoute.name
          console.log('destroyed currentRouter = ', currentRt)
            window.removeEventListener('popstate', this.funBack, false)
      }
    })
  }

}

main.js

import Minxin from './components/js/Minxin'
......
Vue.use(Minxin)

执行结果

我怀疑你有多个组件，所以才会执行多次，你试一下吧console.log打印的currentRt换成this，看看this是不是相同的对象
