如何在 react-leaflet v3 中绘制形状

如何解决如何在 react-leaflet v3 中绘制形状

您对 react-leafletV3 实现绘图功能有什么想法吗？ 我添加了一个事件侦听器，但它不起作用并且对任何事情都没有反应。

import boto3
import json

access_key = "XXXXXXXXXX"
secret_key = "XXXXXXXXXXXXXXXXXXXXX"
client = boto3.client('ec2',aws_access_key_id=access_key,aws_secret_access_key=secret_key,region_name='us-east-1')

ec2_result = client.describe_instances(
    Filters=[
        {
            'Name': 'tag:Name','Values': ['?avi*']
        }
    ]
)

#ids= [ec2_result['Reservations'][0]['Instances'][i]['InstanceId'] for i in range(len(ec2_result['Reservations'][0]['Instances']))]
#print(ids)
print(ec2_result)

解决方法

这是对我有用的代码。我添加了一个事件侦听器来侦听创建的图层，并在创建图层后添加了要素组图层。我已经提到这部分是必需的，因为我已经在选项对象中进行了评论。

      edit: {
        featureGroup: editableLayers,//REQUIRED!!
      }

  useEffect(() => {
    if (!map) return;

    map.addEventListener("mousemove",function (event) {
      setCoords({ lat: event.latlng.lat,lng: event.latlng.lng });
    });

    const editableLayers = new L.FeatureGroup();
    map.addLayer(editableLayers);

    const options = {
      position: "topleft",draw: {
        polyline: false,polygon: false,rectangle: {
          shapeOptions: {
            clickable: false,color: "dodgerblue",},edit: {
        featureGroup: editableLayers,//REQUIRED!!
      },};

    const drawControl = new L.Control.Draw(options);
    map.addControl(drawControl);

    map.on(L.Draw.Event.CREATED,function (e) {
      var type = e.layerType,layer = e.layer;

      if (type === "marker") {
        layer.bindPopup("A popup!");
      }

      editableLayers.addLayer(layer);
    });

    const leftLayer = L.tileLayer(
      layers[leftLayerIndex].url,layerOptions
    ).addTo(map);

    const rightLayer = L.tileLayer(
      layers[rightLayerIndex].url,layerOptions
    ).addTo(map);

    const sbs = L.control.sideBySide(leftLayer,rightLayer).addTo(map);
    setSideBySide(sbs);
  },[map]);
