- 下拉刷新问题
* webview渲染时，建议使用页面级的原生下拉刷新，性能更好。如一定要在webview中自定义下拉刷新，建议插件市场搜索[虚拟列表](https://ext.dcloud.net.cn/search?q=%E4%B8%8B%E6%8B%89%E5%88%B7%E6%96%B0)，这些专业组件使用wxs、renderjs等技术避免通信阻塞。
- scroll-view是区域滚动，不会触发页面滚动，无法触发pages.json配置的下拉刷新、页面触底onReachBottomDistance、titleNView的transparent透明渐变。但在app-uvue下，scroll-view如果是页面顶级节点，则等同于页面滚动。[详见](uni-app-x/css/README.md#pagescroll)
- webview渲染时，scroll-view的滚动条设置，可通过css的-webkit-scrollbar自定义，包括隐藏滚动条。
- webview渲染时，scroll-view的滚动条设置，可通过css的-webkit-scrollbar自定义，但::-webkit-scrollbar 仅在基于 Blink 或 WebKit 的浏览器（例如，Chrome、Edge、Opera、Safari、iOS 上所有的浏览器，以及其他基于 WebKit 的浏览器）上可用。滚动条样式的标准方法可在firefox直接使用 scrollbar-color 和 scrollbar-width属性。

在app-uvue中，其实没有页面级滚动，scroll-view也不存在原生组件层级、下拉刷新性能问题。但app-uvue里使用长列表，请务必使用list-view组件，这个组件内置了recycle-view机制，不管列表多长，都可以通过回收不显示的列表来保证高性能。[详见](list-view.md)
