mapbox Style规范：整理一份完整的Mapbox Style 规范 - 知乎
1、初始化地图
javascript
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
javascript
this.mapboxMap.addLayer({
id: 'tilelayer',
//取值参考：https://docs.mapbox.com/style-spec/reference/layers/#type
type:"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
javascript
//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
javascript
/**
* @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
javascript
//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

try{
this.mapboxMap.setBearing(degree);
this.callbackFunc({
code: 1,
msg: "设置成功！"
},callback);
}catch(err){
this.callbackFunc("未知错误");
throw err;
}
},18、设置地图中心点
javascript
/**
* @description 设置地图中心点 接收格式Array
* pointArray：Array 举例[116, 39] 必传
*/
setCenter(pointArray,callback){
try{
this.mapboxMap.setCenter(pointArray);
this.callbackFunc({
code: 1,
msg: "设置成功！"
},callback);
}catch(err){
this.callbackFunc("未知错误");
throw err;
}
},19、开启/关闭地图事件监听
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
javascript
//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);
},
dragBack(){
this.setCenter([mapCenter.lng,mapCenter.lat]);
},20、部分方法调用示例
