menu 有这个 android 的水波纹效果是不是不太好？

[paranoidjk]

CI lint 没问题，应该是你本地的依赖版本不同

[cncolder]

@paranoidjk List.Item 的水波纹效果的实现方式有待商榷，默认情况下 platform='cross' 还会检测 navigator.userAgent，现阶段要想支持 SSR 就必须在服务端传入 platform。

[paranoidjk]

@cncolder 这个问题是通用的，好几个组件都有 platform 这个api，https://github.com/ant-design/ant-design-mobile/search?l=TypeScript&q=platform&type=&utf8=%E2%9C%93 如果ssr的时候服务端指定 platform 其实也不太好指定哪个。

你看看你有没有意向重构一下，platform="cross"的时候把真正的渲染延迟到componentDidMount之后做，就像 #1153 这里

[cncolder]

@paranoidjk 目前有3个组件：ListItem Modal Switch

我在想 ListItem 这个组件使用上比较普遍，同一个页面会出现很多次，多一次 render 对 ListItem 的影响应该是最大的。

[paranoidjk]

@cncolder 看了下 ListItem 的实现其实也不太好，https://github.com/ant-design/ant-design-mobile/blob/master/components/list/ListItem.web.tsx#L131 这里可以去掉 isAndroid 的判断，改成默认display: none，那就不用在 render 里依赖 navigator 了

[cncolder]

@paranoidjk 你是说在 onClick 里加一行

if (!isAndroid) coverRipleStyle.display = 'none';

或者这样行不行，删掉 render 里的 isAndroid，让 iOS 也渲染一条 <div style={coverRipleStyle} className={ripleCls} /> 貌似也没什么问题。

[paranoidjk]

@cncolder 我的意思也是就始终渲染一个不可见的div，按这个方案做吧
