import imgDrawing from 'img-drawing'
export default {
  data() {
    return {
      drawingStatus: false,
      imgBase64: ''
    }
  },
  methods: {
    openDrawing(){
      this.imgUrl = '/assets/images/img_03.jpeg'
      this.drawingStatus = true
    },
    closeDrawing(imgBase64){
      console.log(imgBase64 ? '用户点击了保存' : '用户点击了取消')
      this.imgBase64 = imgBase64
      this.drawingStatus = false      
    }
  },
  components: {
    imgDrawing
  }
}
</script>

<style scoped lang="scss">
.drawing-wrap{
  position: fixed;
  left: 0;
  right: 0;
  top: 0; 
  bottom: 0; 
  z-index: 2000;
  /* z-index: 2000是个合适的值可以刚好不覆盖elementUi */
}
</style>
