export default router

第二步 在view 下建一个IFrame》》IFrame.vue页面

<template>
    <div class="iframe-container">
        <iframe :src="src" scrolling="auto" frameborder="0" class="frame" :onload="onloaded()">
        </iframe>
    </div>
</template>

<script>
export default {
  data () {
    return {
      src: '',
      loading: null
    }
  },
  methods: {
  // 获取路径
    resetSrc: function (url) {
      this.src = url
      console.log(url)
      this.load()
    },
    load: function () {
      this.loading = this.$loading({
        lock: true,
        text: 'loading...',
        spinner: 'el-icon-loading',
        background: 'rgba(0, 0, 0, 0.5)',
        // fullscreen: false,
        target: document.querySelector('#main-container ')
      })
    },
    onloaded: function () {
      if (this.loading) {
        this.loading.close()
      }
    }
  },
  mounted () {
    this.resetSrc(this.$store.state.iframe.iframeUrl)
  },
  watch: {
    $route: {
      handler: function (val, oldVal) {
      // 如果是跳转到嵌套页面，切换iframe的url
        this.resetSrc(this.$store.state.iframe.iframeUrl)
      }
    }
  }
}
</script>

<style lang="scss" scoped>
.iframe-container {
  position: absolute;
  top: 0px;
  left: 0px;
  right: 0px;;
  bottom: 0px;
  .frame {
    width: 100%;
    height: 100%;
  }
}
</style>

第三步 在store 文件下建一个iframe.js 文件

export default {
  state: {
    iframeUrl: [], // 当前嵌套页面路由路径
    iframeUrls: [] // 所有嵌套页面路由路径访问URL
  },
  getters: {},
  mutations: {
    setIFrameUrl (state, iframeUrl) { // 设置iframeUrl
      state.iframeUrl = iframeUrl
    },
    addIFrameUrl (state, iframeUrl) { // iframeUrls
      state.iframeUrls.push(iframeUrl)
    },
    setIFrameName (state, iframeUrl) { // iframeUrls
      state.setIFrameName= iframeUrl
    }
  },
  action: {}
}
