展开：Page({onReady:function(e){//使用wx.createMapContext获取map上下文this.mapCtxwx.createMapContext(myMap)},getCenterLocation:function(){this.mapCtx.getCenterLocation({success:function(res){console.log(res.longitude)console.log(res.latitude)}})},})//我的代码onLoad:function(options){varthatthis;that.mapCtxwx.createMapContext(myMap);//获取当前位置并移动到此位置wx.getLocation({success:function(res){varlongituderes.longitude;varlatituderes.latitude;//console.log(res)that.setData({longitude:longitude,latitude:latitude})setTimeout(function(){that.mapCtx.moveToLocation();},300);}});},onShow:function(){varthatthis;//获取中心位置console.log(that.mapCtx);that.mapCtx.getCenterLocation({success:function(res){console.log(res);varcenterLgtres.longitude;varcenterLatres.latitude;if(centerLgtthat.data.centerLgtcenterLatthat.data.centerLat){return;}else{that.setData({centerLgt:centerLgt,centerLat:centerLat});getMarkers.call(that,centerLat,centerLgt);}}});},//console返回的结果callbackId:callback110_0_4errMsg:getMapCenterLocation:oklatitude:0longitude:0mapId:0method:getMapCenterLocation是什么原因造成的呢了解更多
