使用插件，安装

javascript 复制代码

npm install mapbox-gl-draw-circle   //绘制圆
npm install @mapbox/mapbox-gl-draw   //绘制点线面删除

vue案例，封装的组件

javascript 复制代码

使用方式，通过tools控制需要哪些绘制控件

javascript 复制代码

    <draw-map
      :tools="{
        // point: true,
        // line_string: true,
        polygon: true,
        trash: true,
        // circle: true,
      }"
    ></draw-map>
