模块 element-resize-detector

import elementResizeDetectorMaker from 'element-resize-detector'

    const _this = this

    const erd = elementResizeDetectorMaker()

    erd.listenTo(document.getElementById("app"),(element)=>{

        _this.$nextTick(()=>{

           this.$refs.tapp.style.height= element.offsetHeight+'px'

        })

    })
