vue组件和页面的高度根据屏幕大小自适应

  data() {
    return {
      clientHeight: document.body.clientHeight
    }
  }

  mounted() {
    const that = this
    window.onresize = () => {
      return (() => {
        window.screenHeight = document.body.clientHeight
        that.clientHeight = window.screenHeight
      })()
    }
  },
  watch: {
    clientHeight(val) {
      // 为了避免频繁触发resize函数导致页面卡顿，使用定时器
      if (!this.timer) {
        // 一旦监听到的screenWidth值改变，就将其重新赋给data里的screenWidth
        this.clientHeight = val
        this.timer = true
        let that = this
        setTimeout(function() {
          // 打印screenWidth变化的值
          console.log(that.clientHeight)
          that.timer = false
        }, 400)
      }
    }
  }

  <div class="review-options-details" :style="{ height: clientHeight-194 + ‘px‘ }">
