vux， vue如何控制微信自带的返回按钮，让其返回其他页面？

<script>
  import { mapState } from 'vuex'
  export default{
    name: 'clockFx',
    data () {
      return {
      }
    },
    computed: mapState({
      listenFlag: state => state.listenFlag
    }),
    methods: {
      verify: function () {
        let thisObj = this
        if (this.listenFlag) {
          window.popstate = function () {
            thisObj.cancelBack()
            window.location.href = '#/LearningContent'  //要跳转的链接
          }
          window.addEventListener('popstate', window.popstate, false)
        }
      },
      cancelBack: function () {
        this.$store.commit('listenFlag', false)
        window.removeEventListener('popstate', window.popstate)
      }
    },
    created: function () {
      this.verify()
    },
    watch: {
      '$route': 'verify'
    }
  }
</script>
