1. 使用场景

在开发WebGIS应用时，我们常需要将自定义UI组件与地图元素结合。本文介绍如何将Vue组件集成到Mapbox/Maplibre的Marker标记点和Popup弹窗中，实现动态交互式的地图功能。

2. 为什么需要特殊处理？

在常规开发中我们大多的处理是

const tipsEle = document.createElement("div")tipsEle.setAttribute("class", "tips")tipsEle.style.color = "#e73f32"tipsEle.style.fontSize = "12px"tipsEle.style.fontWeight = "400"tipsEle.innerHTML = "删除"const tipsOption = {element: tipsEle,anchor: "left",offset: [-45, 30],}new maplibregl.Marker(tipsOption).setLngLat(coords).addTo(map)

这样的写法显而易见维护难，调试难，ui在复杂一点复杂程度也跟着上去了，如果换成组件形式的话，所有问题迎刃而解了。

3. 使用createVNode实现

/*** @description: 创建地图Marker 和 Popup 组件, 渲染自定义组件* @author: jihai* @createTime: 2025/03/05 15:05:01*/
import {createVNode, render} from "vue";
import * as maplibregl from 'maplibre-gl';class CreateVNode{declare map:anydeclare coordinates:anydeclare markerComponentId: stringdeclare marker:anydeclare markerElement: anydeclare popupComponentId: stringdeclare popup:anydeclare popupElement: anyconstructor(option: {map: any,coordinates: any}) {const {map, coordinates} = optionthis.map = mapthis.coordinates = coordinatesthis.markerComponentId = `markerComponentId-${performance.now().toString()}`this.marker = nullthis.markerElement = nullthis.popupComponentId = `popupComponentId-${performance.now().toString()}`this.popup = nullthis.popupElement = null}createMarker(options: {component: {component: any, // 自定义vue组件props: any      // 自定义组件props},config?: {offset: number[],anchor: string}}){const { component, config } = optionsconst app = createVNode(component?.component, {data: component?.props})this.markerElement = document.createElement("div")this.markerElement.setAttribute("id", this.markerComponentId)this.marker = new maplibregl.Marker({element: this.markerElement,anchor: config?.anchor ?? 'bottom',offset: config?.offset ?? [0, 0]}).setLngLat(this.coordinates).addTo(this.map)render(app, this.markerElement)}createPopup(options: {component: {component: any, // 自定义vue组件props: any      // 自定义vue组件props},config?: {offset: number[],anchor: string,closeButton: boolean}}){const { component, config } = optionsconst app = createVNode(component?.component, {data: component?.props})this.popupElement = document.createElement("div")this.popupElement.setAttribute("id", this.popupComponentId)this.popup = new maplibregl.Popup({className: 'custom-popup', closeButton: config?.closeButton ?? true, anchor: config?.anchor ?? 'bottom'}).setMaxWidth('none').setOffset(config?.offset ?? [0, 0]) // 这里设置偏移量.setLngLat(this.coordinates).setDOMContent(this.popupElement).addTo(this.map)render(app, this.popupElement)}removeMarker(){if(this.marker){this.marker.remove()}if(this.markerElement){this.markerElement.remove()}}removePopup(){if(this.popup){this.popup.remove()}if(this.popupElement){this.popupElement.remove()}}remove(){this.removeMarker()this.removePopup()}
}export default CreateVNode

4. 使用方法

  // 简单使用 具体使用根据业务场景合理清除图层let marker = new CreateVNode({map: map,coordinates: coordinates})marker.createMarker({component: {component: markerComp,props: markerProps},config: {offset: [0, 120],anchor: 'bottom'}})//  图层清除marker.removeMarker()marker = null
