PolyEditor 编辑器

折线、多边形编辑插件，用于编辑 Polygon 或 Polyline 对象，支持AMap JS API v1.4.xxx 和 v2.0.xxx。官方示例

import { PolyEditor } from '@uiw/react-amap';
// 或者单独安装使用
import { PolyEditor } from '@uiw/react-amap-poly-editor';

注意： 官方文档已经没有这个 API 的文档了

基本用法

注意，需要加载 <APILoader plugin="AMap.PolyEditor">，需要加载 AMap.PolyEditor 插件，如果点击进入当前页面，需要 刷新 页面。

<APILoader plugin="AMap.PolyEditor">

多边形编辑

  const [active, setActive] = useState(false);
  // 多边形轮廓线的节点坐标数组
  const path = [

    [116.410703, 39.897555],

    [116.389846, 39.891365],
  ];
    const [polygonPath,setPolygonPath]=useState(path);
  return (
    <>
      <button onClick={() => setShow(!show)}>
        {show ? '隐藏' : '显示'}
      </button>
      <button onClick={() => setActive(!active)}>
        {active ? '结束' : '开始'}编辑

            />
          </Polygon>
        </Map>
      </div>
    </>
