页面传值也不麻烦啊！利用组件的properties属性接收值。使用组件的页面js用onPageScroll,设置data中的显示标识如 showBotton,onPageScroll更新showBotton的显示与否状态。使用组件页面的wxml调用组件时，组件属性=showBotton，如<ToTopBtn showBtn="{{showBotton}}"></ToTopBtn>，组件内根据属性showBtn来判断显示与否<view class="goTop" hidden="{{!showBtn}}" bindtap="goTop">
自定义组件中如何使用onPageScroll？我打算封装个自定义的一键置顶组件（许多页面需要用到），但是onPageScroll好像在组件中用不了，现在是在用到的页面使用onPageScroll然后传值过去，但这样有点麻烦，有什么办法在组件中获取到scrollTop的值？
2022-10-10我也是新建组件后，就出现找不到组件wxml文件的错误。我的解决办法是：清空全部缓存>重新编译。这样就没错误出现了。

2022-09-23demo.js是修改样式模板的文件，在根目录下自己新建，主要代码如下： const wxml = ` <view class="container"> <image class="img" src="/image/sharebg.jpg"></image> </view> </view> ` const style = { container: { width: 300, height: 200, flexDirection: 'row', justifyContent: 'space-around', backgroundColor: '#ccc', alignItems: 'center', }, itemBox: { width: 80, height: 60, }, text: { width: 80, height: 60, textAlign: 'center', verticalAlign: 'middle', }, img: { width: '100', height: '100', } } module.exports = { wxml, style }
这句话什么意思？在哪引入的wxml，style。我这没有demo.js这个文件。能不能说清楚啥意思const {wxml, style} = require('./demo.js')
