使用6s运行小程序官网自带的地图程序，点击Marker时不响应事件，求解决。 版本信息如下图： [图片] 代码如下： [代码]<map id="map" longitude="113.324520" latitude="23.099994" scale="14" controls="{{controls}}" bindcontroltap="controltap" markers="{{markers}}" bindmarkertap="markertap" polyline="{{polyline}}" bindregionchange="regionchange" show-location style="width: 100%; height: 300px;">map>[代码][代码]// map.jsPage({  data: {    markers: [{      iconPath: "/resources/others.png",      id: 0,      latitude: 23.099994,      longitude: 113.324520,      width: 50,      height: 50    }],    polyline: [{      points: [{        longitude: 113.3245211,        latitude: 23.10229      }, {        longitude: 113.324520,        latitude: 23.21229      }],      color:"#FF0000DD",      width: 2,      dottedLine: true    }],    controls: [{      id: 1,      iconPath: '/resources/location.png',      position: {        left: 0,        top: 300 - 50,        width: 50,        height: 50      },      clickable: true    }]  },  regionchange(e) {    console.log(e.type)  },  markertap(e) {    console.log(e.markerId)  },  controltap(e) {    console.log(e.controlId)  } })[代码]

加载大概2000个左右的覆盖物时操作地图很卡顿，请问有什么办法可以解决？地图是否支持聚合功能？谢谢

在华为荣耀note8手机上点击地图上Marker时没有任何事件响应，其他手机上都可以，使用新建一个和手机宽(411)、高(695)、DPR(3.5)一样的模拟器，也没有响应，求解决

android地图上有卫星图、2D平面、3D俯视等，请问小程序什么时候能支持多种模式，特别的卫星图模式的显示啊？谢谢

想实现点击一个cover-image时弹出日期选择对话框，但由于picker不能在cover-view中嵌套，因此采取了点击时进入另外一个页面，在另外一个页面进入日期对话框，但这就导致多了一个操作步骤，进入新页面后还需要再次点击一下才能弹出日期框，想请教下怎么能让如下页面加载时默认就弹出日期选择框，而不用再点一次？ <view class="section_container"> <picker mode="date" value="{{date}}" start="2017-05-01" end="2027-09-01" bindchange="bindDateChange"> <view class="picker"> 请选择日期: {{date}} </view> </picker> </view>

Android真机上最新的微信版本和SDK版本，marker的label属性不起作用，但在模拟器下显示效果很好，什么原因？ 设置label属性的代码  label: { color: '#475575', fontSize: 32, content:‘101’, x:-25, y:-60}

目前微信最新版本是6.5.10,小程序SDK版本是1.4.3，发现很多人的微信版本还是6.5.8,如何在不升级微信版本的情况下只升级SDK版本到1.4.3呢

map里面有个cover-view,cover-view包含了一个Button，模拟器上显示完美，真机上确没有显示出来，什么原因？ <view class="map_container">    <map class="map" id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="14" show-location="true" markers="{{markers}}" bindmarkertap="makertap"  polyline="{{polyline}}" bindtap="maptap">   <cover-view class="car_info" hidden="{{carInfohidden}}">      <cover-view class="otherInfo">                 <cover-view class="basicOtherInfo">            <cover-view style="display: flex;"><cover-view  class="carTextFlagCss">领航员:</cover-view><cover-view class="carTextCss">{{placeData.pilotName}}</cover-view> </cover-view>             <cover-view style="display: flex;"><cover-view  class="carTextFlagCss">俱乐部:</cover-view><cover-view class="carTextCss">{{placeData.clubName}}</cover-view> </cover-view>             <cover-view style="display: flex;"><cover-view  class="carTextFlagCss">组别:</cover-view><cover-view class="carTextCss">{{placeData.groupName}}</cover-view> </cover-view>         </cover-view>         <button type="warn" size="50rpx" style="width:400rpx;margin-top:20rpx" bindtap="showHistoryTrace">告警列表</button>   </cover-view>   </cover-view>   </map>  </view>  <audio  src="{{src}}" id="myAudio" ></audio>

从远程服务器获取到了原始真实坐标，使用算法将wgs84坐标转换成gcj02坐标，再地图上显示时与实际位置误差很大，但同样的真实坐标转换成百度BD-09坐标系在android下百度地图显示就非常准确，请问微信小程序设置Marker经纬度时使用的什么坐标系？谢谢。 以下是转换方法： class GPSTransformWX {      constructor(param) {     //  this.ak = param["ak"];   }    transform (wgLat, wgLon) {      var a = 6378245.0;      var ee = 0.00669342162296594323;     if (this.outOfChina(wgLat, wgLon)) {       return [wgLat, wgLon];     }     var dLat = this.transformLat(wgLon - 105.0, wgLat - 35.0);     var dLon = this.transformLon(wgLon - 105.0, wgLat - 35.0);     var radLat = wgLat / 180.0 * Math.PI;     var magic = Math.sin(radLat);     var magic = 1 - ee * magic * magic;     var sqrtMagic = Math.sqrt(magic);     dLat = (dLat * 180.0) / ((a * (1 - ee)) / (magic * sqrtMagic) * Math.PI);     dLon = (dLon * 180.0) / (a / sqrtMagic * Math.cos(radLat) * Math.PI);          var mgLat = Number(wgLat) + Number(dLat);     var mgLon = Number(wgLon) + Number(dLon);     console.log("纬度"+dLat + "**" + wgLat + " ****" + mgLat);     console.log("经度"+dLon + "**" + wgLon + " ****" + mgLon);     return [mgLat, mgLon];   }   outOfChina (lat, lon) {     if (lon < 72.004 || lon > 137.8347)       return true;     if (lat < 0.8293 || lat > 55.8271)       return true;     return false;   }  transformLat  (x, y) {    console.log("x="+x+" y="+y);     var ret = -100.0 + 2.0 * x + 3.0 * y + 0.2 * y * y + 0.1 * x * y + 0.2 * Math.sqrt(Math.abs(x));     ret += (20.0 * Math.sin(6.0 * x * Math.PI) + 20.0 * Math.sin(2.0 * x * Math.PI)) * 2.0 / 3.0;     ret += (20.0 * Math.sin(y * Math.PI) + 40.0 * Math.sin(y / 3.0 * Math.PI)) * 2.0 / 3.0;     ret += (160.0 * Math.sin(y / 12.0 * Math.PI) + 320 * Math.sin(y * Math.PI / 30.0)) * 2.0 / 3.0;     return ret;   }; transformLon (x, y) {     var ret = 300.0 + x + 2.0 * y + 0.1 * x * x + 0.1 * x * y + 0.1 * Math.sqrt(Math.abs(x));     ret += (20.0 * Math.sin(6.0 * x * Math.PI) + 20.0 * Math.sin(2.0 * x * Math.PI)) * 2.0 / 3.0;     ret += (20.0 * Math.sin(x * Math.PI) + 40.0 * Math.sin(x / 3.0 * Math.PI)) * 2.0 / 3.0;     ret += (150.0 * Math.sin(x / 12.0 * Math.PI) + 300.0 * Math.sin(x / 30.0 * Math.PI)) * 2.0 / 3.0;     return ret;   }; } module.exports.GPSTransformWX = GPSTransformWX;
