vue中实现supermap标绘
Vue 中实现 SuperMap 标绘的方法
在 Vue 项目中集成 SuperMap 进行地图标绘,可以通过 SuperMap 提供的 JavaScript API 实现。以下是具体实现步骤:
安装 SuperMap 相关依赖
确保项目中已引入 SuperMap 的 JavaScript API,可以通过 CDN 或本地引入方式。在 Vue 项目的 public/index.html 中通过 CDN 引入:
<script src="https://iclient.supermap.io/web/libs/iclient8c/8.1.1-20093/iclient8c.min.js"></script>
创建地图容器 在 Vue 组件的模板中添加地图容器:
<template>
<div id="map-container" style="width: 100%; height: 100vh"></div>
</template>
初始化地图
在 Vue 组件的 mounted 生命周期中初始化地图:

mounted() {
const map = new SuperMap.Map("map-container", {
controls: [new SuperMap.Control.Navigation(), new SuperMap.Control.Zoom()],
projection: "EPSG:4326"
});
const layer = new SuperMap.Layer.TiledDynamicRESTLayer("World", "https://iserver.supermap.io/iserver/services/map-world/rest/maps/World", null, { maxResolution: "auto" });
layer.events.on({ "layerInitialized": () => map.addLayer(layer) });
}
添加标绘功能 创建标绘工具并添加到地图:
const drawControl = new SuperMap.Control.DrawFeature(
new SuperMap.Handler.Path(SuperMap.Handler.Feature, {
"done": (feature) => {
const vectorLayer = new SuperMap.Layer.Vector("Vector Layer");
map.addLayer(vectorLayer);
vectorLayer.addFeatures([feature]);
}
}),
{ title: "Draw Polyline" }
);
map.addControl(drawControl);
标绘类型扩展
点标绘
通过修改 Handler 类型实现点标绘:

new SuperMap.Handler.Point(SuperMap.Handler.Feature, {
"done": (feature) => {
// 处理点要素
}
})
多边形标绘 使用多边形处理器:
new SuperMap.Handler.Polygon(SuperMap.Handler.Feature, {
"done": (feature) => {
// 处理多边形要素
}
})
样式自定义
设置标绘样式
通过 Style 对象自定义标绘样式:
const style = new SuperMap.Style({
strokeColor: "#ff0000",
strokeWidth: 2,
fillColor: "#ffffff",
fillOpacity: 0.5
});
vectorLayer.style = style;
事件处理
添加交互事件 为标绘要素添加交互事件:
vectorLayer.events.on({
"featureclick": (event) => {
console.log("Feature clicked:", event.feature);
}
});
完整示例组件
<template>
<div id="map-container"></div>
</template>
<script>
export default {
mounted() {
this.initMap();
},
methods: {
initMap() {
const map = new SuperMap.Map("map-container", {
controls: [new SuperMap.Control.Navigation()],
projection: "EPSG:4326"
});
const layer = new SuperMap.Layer.TiledDynamicRESTLayer(
"World",
"https://iserver.supermap.io/iserver/services/map-world/rest/maps/World",
null,
{ maxResolution: "auto" }
);
layer.events.on({
"layerInitialized": () => {
map.addLayer(layer);
this.addDrawControls(map);
}
});
},
addDrawControls(map) {
const vectorLayer = new SuperMap.Layer.Vector("Vector Layer");
map.addLayer(vectorLayer);
const handlers = {
point: new SuperMap.Handler.Point(SuperMap.Handler.Feature, {
"done": (feature) => vectorLayer.addFeatures([feature])
}),
line: new SuperMap.Handler.Path(SuperMap.Handler.Feature, {
"done": (feature) => vectorLayer.addFeatures([feature])
}),
polygon: new SuperMap.Handler.Polygon(SuperMap.Handler.Feature, {
"done": (feature) => vectorLayer.addFeatures([feature])
})
};
Object.values(handlers).forEach(handler => {
map.addControl(new SuperMap.Control.DrawFeature(handler));
});
}
}
};
</script>
以上代码展示了在 Vue 中集成 SuperMap 并实现基本标绘功能的方法,包括点、线和多边形的绘制。开发者可以根据实际需求扩展更多功能,如样式自定义、事件处理等。
