展开:当前Bug的表现（附上截图）可以看到拖动地图出现明显的闪烁使用微信小程序地图动态展示marker，当用户拖拽或缩放地图时需要加载当前区域内的marker，但是使用setData({markers:markers})出现很明显的闪烁现象，该怎么解决预期表现移动地图，动态加载marker，地图上的marker无明显闪烁现象，让用户感觉不到marker刷新了或者能否提供插入或删除单个marker的方法，这种批量操作marker的效率太低了复现路径用鼠标拖动地图，marker重新加载会出现闪烁复现Demodemo如下：mapwxml：<viewclass=map_container<mapclass=mapid=maplongitude={{longitude}}latitude={{latitude}}scale=14showlocation=truemarkers={{markers}}bindregionchange=regionchange<map<viewmapwxss：map_container{position:absolute;top:0;bottom:0;left:0;right:0;}map{width:100%;height:100%;}mapjsvaramapFile=require(libsamapwxjs);varmarkersData=[];Page({data:{markers:[],latitude:32864377803922,longitude:115788491268263},onLoad:function(){varthat=this;},onShow:function(){模拟从服务器加载设备模拟网络延迟setTimeout(()={varmarkers=thisgetMarkers();thissetData({markers:markers});},1000);},regionchange:function(res){if(restype==end){consolelog(加载设备);模拟从服务器加载设备模拟网络延迟setTimeout(()={varmarkers=thisgetMarkers();thissetData({markers:markers});},1000);}},getMarkers:function(){varmarkers1=[{latitude:32863684789997,longitude:115794747394735},{latitude:32866150490718,longitude:115779776056454},{latitude:3285699840912,longitude:115793706230259},{latitude:32868802796587,longitude:115795851934883},{latitude:32868802796587,longitude:115795851934883},{latitude:32865037454128,longitude:115784221396101},{latitude:32861683316431,longitude:115794735614756},{latitude:3286145345,longitude:1157946734},{latitude:32866980115902,ongitude:115779949},{latitude:32861960286233,longitude:115794732449203},{latitude:32861960286233,longitude:115794732449203},{latitude:32860691527707,longitude:115783249338155},{latitude:32858660704851,longitude:115782761369842},{latitude:32861673318033,longitude:115782898390111},{latitude:32859451402325,longitude:115783271050545},{latitude:32858075553001,longitude:115782085844506},{latitude:3285980061309,longitude:115782478686392},{latitude:32859026954912,longitude:115783450959086},{latitude:32858902233697,longitude:115786543290987}];varmarkers2=[{latitude:32863684789997,longitude:115794747394735},{latitude:32859749503874,longitude:115782486744537},{latitude:32865891748675,longitude:115778707367095},{latitude:32868802796587,longitude:115795851934883},{latitude:32868802796587,longitude:115795851934883},{latitude:32865037454128,longitude:115784221396101},{latitude:32861683316431,longitude:115794735614756},{latitude:3286145345,longitude:1157946734},{latitude:32866980115902,ongitude:115779949},{latitude:32861960286233,longitude:115794732449203},{latitude:32861960286233,longitude:115794732449203},{latitude:32860691527707,longitude:115783249338155},{latitude:32858660704851,longitude:115782761369842},{latitude:32861673318033,longitude:115782898390111},{latitude:32859451402325,longitude:115783271050545},{latitude:32858075553001,longitude:115782085844506},{latitude:3285980061309,longitude:115782478686392},{latitude:32859026954912,longitude:115783450959086},{latitude:32858902233697,longitude:115786543290987}];varmarkers3=[{latitude:32863684789997,longitude:115794747394735},{latitude:32859749503874,longitude:115782486744537},{latitude:3285699840912,longitude:115793706230259},{latitude:32868802796587,longitude:115795851934883},{latitude:32868802796587,longitude:115795851934883},{latitude:32865037454128,longitude:115784221396101},{latitude:32865902040263,longitude:115780964494169},{latitude:3286145345,longitude:1157946734},{latitude:32866980115902,ongitude:115779949},{latitude:32861960286233,longitude:115794732449203},{latitude:32861960286233,longitude:115794732449203},{latitude:32860691527707,longitude:115783249338155},{latitude:32858660704851,longitude:115782761369842},{latitude:32861673318033,longitude:115782898390111},{latitude:32859451402325,longitude:115783271050545},{latitude:32858075553001,longitude:115782085844506},{latitude:3285980061309,longitude:115782478686392},{latitude:32859026954912,longitude:115783450959086},{latitude:32858902233697,longitude:115786543290987}];varrm=(Mathrandom()*3)toFixed(0);consolelog(rm=+rm);if(rm==1){returnmarkers1;}elseif(rm==2){returnmarkers2;}else{returnmarkers3;}}})即速小程序：@微信团队
