1、初始化地图
this.mapboxMap = new mapboxgl.Map({container: "mapBoxMapContainer",//容器zoom: mapOptions.zoom ? mapOptions.zoom : 9,//层级center: mapOptions.centerPoint ? mapOptions.centerPoint : [116.39, 39.91],//中心点//图层（可用mapbox提供的在线图层，举例：mapbox://styles/mapbox/streets-v11）style: mapOptions.mapBoxUrl,//true则多个源的符号会相互碰撞。false则对每个源中的符号分别运行碰撞检测crossSourceCollisions: false
});2、单独添加瓦片
this.mapboxMap.addLayer({id: 'tilelayer',//取值参考：https://docs.mapbox.com/style-spec/reference/layers/#typetype:"raster",//取值参考：https://docs.mapbox.com/style-spec/reference/sources/source:{"type": "raster","tiles": [mapOptions.mapBoxUrl],}
});3、开启绘制方法
引入mapbox-gl-draw.js和mapbox-gl-draw.css
//地图加载完成后 初始化插件
this.mapboxMapDraw = new MapboxDraw({displayControlsDefault: false,//不显示默认的控件按钮
});
this.mapboxMap.addControl(this.mapboxMapDraw);/*** @description 绘制方法* type：String 绘制类型 举例'draw_point'* dataId：String 上层界面使用*/
openDraw(drawOption,callback){var that = this;if(drawOption){//取值"draw_point" "draw_line_string" "draw_polygon"that.mapboxMapDraw.changeMode(drawOption?.type);that.mapboxMap.on("draw.create", function (feature) {if(feature?.features.length){that.callbackFunc({code: 1,geometryId: feature.features[0]?.id,point: feature.features[0]?.geometry?.coordinates,dataId: drawOption?.dataId},callback);}else{that.callbackFunc("参数错误");}});that.mapboxMap.on("draw.update", function (feature) {if(feature?.features.length){that.callbackFunc({code: 1,geometryId: feature.features[0]?.id,point: feature.features[0]?.geometry?.coordinates,dataId: drawOption?.dataId},callback);}else{that.callbackFunc("参数错误");}});that.mapboxMap.on("draw.delete", function (feature) {});}else{that.callbackFunc("参数错误");}
},4、移除绘制数据
/*** @description 删除绘制的点线面 接收格式 String* removeIdArray：Array 唯一标识的集合，在绘制的方法里会返回 必传*/
removeDrawById(removeIdArray,callback){if(removeIdArray?.length){try{removeIdArray.forEach((item,index)=>{if(this.mapboxMapDraw.get(item.geometryId)){this.mapboxMapDraw.delete(item.geometryId);}});}catch(err){this.callbackFunc("未知错误");throw err;}}else{this.callbackFunc("参数错误");}
},5、拾取经纬度
//开启拾取方法 考虑项目是否在pc端打开 分别判断
pickUpLatLng(callback){if(this.getBrowser() == "pc" || this.getBrowser() == "linux"){this.mapboxMap.on('click',(event) =>{this.pickUpLatLngMonitor(event,callback)});}else{this.mapboxMap.on('touchend',(event) => {this.pickUpLatLngMonitor(event,callback)});}
},
//检测设备
getBrowser(){var sUserAgent = navigator.userAgent.toLocaleLowerCase();var isLinux = (String(navigator.platform).indexOf("linux") > -1);var bIsAndroid = sUserAgent.match(/android/i) == "android";var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";var bIsCE = sUserAgent.match(/windows nt/i) == "windows nt";if (isLinux) {return "linux";} else if (bIsIpad || bIsIphoneOs) {return "ios";} else if (bIsWM) {return "wp";} else if (bIsCE) {return "pc";} else if (bIsAndroid) {return "android";}
},
//回调给上层经纬度
pickUpLatLngMonitor(e,callback){this.callbackFunc({code:1,data:e.lngLat,msg:"拾取经纬度信息！"},callback);
},6、加点

注：mapbox中关闭监听事件时，必须与开启监听事件的回调函数一致才能成功取消监听
//开启监听地图拖拽（mapbox不支持开启禁止拖拽和禁止平移事件，监听鼠标拖拽后回到原始位置从而实现禁止拖拽的效果）
openListenMapDrag(){mapCenter = this.mapboxMap.getCenter();this.mapboxMap.on('dragend',this.dragBack);
},
//关闭监听地图拖拽
closeListenMapDrag(){this.mapboxMap.off('dragend',this.dragBack);
