数据可视化之大屏模板和自适应放大缩小方法

废话不多说直接上根据屏幕视口大小自动缩放的实现方法

方法一

通过js获取窗口宽高进行缩放建议配合vh，vw食用

<script>
    console.log(window.screen)
    let screenWidth = window.screen.width
    let screenHeight = window.screen.height

    let box = document.querySelector('.box')

    box.style.width = screenWidth + 'px'
    box.style.height = screenHeight + 'px'

    // window.innerWidth
    let pageWidth = window.innerWidth

    let scale = pageWidth / screenWidth

    document.body.style.transform = `scale(${scale})`


    window.onresize = function () {
      let pageWidth = window.innerWidth
      let scale = pageWidth / screenWidth

      document.body.style.transform = `scale(${scale})`

    }
  </script>

然后里面的echarts图表通过监听窗口变化实现自适应

pieChart1为你初始化的图表

window.onresize = function () {
        pieChart1.resize();
      };
