  mounted () {
    const that = this;
    window.onresize = () => {
      return (() => {
        that.screenHeight = window.innerHeight
      })()
    }
  },
  data(){
    return {
      screenHeight: window.innerHeight,
    }
  }

 方案二：

export default {
   data(){
     return {
       screenHeight: window.innerHeight,
     }
   },
    mounted() {
        window.addEventListener(\'resize\', this.onResize);
    },
    beforeDestroy() {
        window.removeEventListener("resize", this.onResize);
    },
    methods: {
        onResize() {
            this.screenHeight = window.innerHeight;
        }
    }
