好像没有解决方案，实时更新运动轨迹也不断闪烁，makers也好，polyline也好，只支持数据整体更新，不支持局部更新，像类似这种写法是不生效的： let points = this.data.lines.length ? this.data.lines[0].points : [] let index = 'lines[0].points['+points.length+']' this.setData({   [index]: {longitude: 121.34, latitude: 35.25} })

微信小程序地图动态加载marker出现闪烁现象

- 当前 Bug 的表现（附上截图） [图片] 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 Demo demo如下： map.wxml： [代码]<[代码][代码]view[代码]

真是搞球，不能直接绑定微信吗，非得弄个邮箱账号，最后又绑定到微信，关键是邮箱账号不够用啊，坑爹呢这是！

微信开放平台和公众平台的账号不通用，但是一个邮箱却又只能注册其中一个

这个是不是有点别扭啊。账号太多就容易丢。然后要注册一堆QQ号。能改一下这个问题吗 ++ 凡是注册过公众平台的账号，登录开放平台都提示密码错误，找回密码就提示邮箱未注册，然后去注册又提示被使用。能不能让账号通用一下，如果牵扯审核之类的，可以登录后提交资质审核，但是没必要这样把账号应生生的分开啊。搞一堆账号好别扭啊。很想在微信平台上就用一个号。

wx:key报错does not look like a valid key name？

[图片] 以前开发也没遇到过这种问题，item.id也没有问题，为什么会报警告
