你好。我先描述下背景吧。 我还没正经开发过小程序,最近在做相关工作(封装一个小程序框架) 比如有这样一个业务场景,一个页面里有一个组件,页面监听了某个子组件的事件,在回调里setData了,而这个子组件因为监听了生命周期或者UI事件也setData了,并 trigger 了页面监听的这个事件。我想了解一下这个过程到底是怎样的?
不太清楚 setData 到 webview 那边的通信时间和内部放置的队列情况,不过应该是宏队列,但是浏览器本身也对宏队列做了优化(比如连续在 setTimeout 0 操作 dom,不论是重绘还是重排,浏览器也会有自己的一套 isNeedRender 的算法优化)
