function getRandomColor() { let rgb = [] for (let i = 0; i < 3; ++i) { let color = Math.floor(Math.random() * 256).toString(16) color = color.length == 1 ?

PS: 最後補充一下video的注意事項:
1. video 組件是由客戶端建立的原生組件,它的層級是最高的。
2. 請勿在 scroll-view 中使用 video 組件。
3. css 動畫對 video 組件無效。git
若是想在video組件上添加組件,可使用cover-view組件,具體使用方法點擊這裏:https://mp.weixin.qq.com/debug/wxadoc/dev/component/cover-view.html。github
