项目介绍

Leaflet.draw 是一个开源的 JavaScript 库，用于在 Leaflet 地图上添加绘图功能。它允许用户在地图上绘制多边形、矩形、圆形、折线等矢量图形，并支持编辑和删除这些图形。Leaflet.draw 的设计目标是既易于终端用户使用，也便于开发者集成。

项目快速启动

安装

首先，克隆项目仓库到本地：

git clone https://github.com/Leaflet/Leaflet.draw.git

然后，进入项目目录并安装依赖：

cd Leaflet.draw
npm install

示例代码

以下是一个简单的示例，展示如何在 Leaflet 地图上启用绘图功能：

    <link rel="stylesheet" href="https://unpkg.com/leaflet-draw/dist/leaflet.draw.css" />

        #map {
            height: 600px;
        }
    </style>

    <script>
        var map = L.map('map').setView([51.505, -0.09], 13);

        L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            attribution: '© OpenStreetMap contributors'
        }).addTo(map);

        var drawnItems = new L.FeatureGroup();
        map.addLayer(drawnItems);

        var drawControl = new L.Control.Draw({
            draw: {
                polyline: true,
                polygon: true,
                rectangle: true,
                circle: true,
                marker: true
            },
            edit: {
                featureGroup: drawnItems
            }
        });
        map.addControl(drawControl);

        map.on(L.Draw.Event.CREATED, function (event) {
            var layer = event.layer;
            drawnItems.addLayer(layer);
        });
    </script>
</body>
