由于项目使用tagsView,关闭当前页面需要通过关闭当前标签来实现 

涉及到几个点：

1. 移除 VisitedView 和 CachedView 中的当前项

2. 跳转到最后一次访问的标签

主要思路：比对 路由路径 ( this.$route.path)

两种方式：

一、 在vue页面直接实现

closePage()
      var currentView = this.$store.state.tagsView.visitedViews[0]
      for (currentView of this.$store.state.tagsView.visitedViews) {
        if (currentView.path === this.$route.path) {
          break
        }
      }
      this.$store.dispatch('tagsView/delView', currentView)
        .then(({ visitedViews }) => {
          if (currentView.path === this.$route.path) {
            const latestView = this.$store.state.tagsView.visitedViews.slice(-1)[0]
            if (latestView) {
              this.$router.push(latestView)
            } else {
              // 如果没有其他标签则跳转到首页
              if (currentView.name === '首页') {
                this.$router.replace({ path: '/redirect' + currentView.fullPath })
              } else {
                this.$router.push('/')
              }
            }
          }
        })

二、在js文件中写自定义函数，在vue页面中调用

import router from '@/router/routers'

// 关闭当前页 关联tagView
export function closePage(store, route) {
  var currentView = store.state.tagsView.visitedViews[0]
  for (currentView of store.state.tagsView.visitedViews) {
    if (currentView.path === route.path) {
      break
    }
  }
  store.dispatch('tagsView/delView', currentView)
    .then(({ visitedViews }) => {
      if (currentView.path === route.path) {
        const latestView = store.state.tagsView.visitedViews.slice(-1)[0]
        if (latestView) {
          router.push(latestView)
        } else {
          if (currentView.name === '首页') {
            router.replace({ path: '/redirect' + currentView.fullPath })
          } else {
            router.push('/')
          }
        }
      }
    })
}
