Two implementation methods for WeChat mini program pull-down refresh and pull-up loading. 1. Use the "onPullDownRefresh" and "onReachBottom" methods to implement pull-down refresh and pull-up loading for the mini program. 2.

Write the "onPullDownRefresh" and "onReachBottom" methods directly in the js file;
xml
<scroll-view scroll-y = true > ......... </scroll-view>
js
onPullDownRefresh: function() { // Do something when pull down. console.log('刷新'); }, onReachBottom: function() { // Do something when page reach bottom. console.log('circle 下一页'); },
2. Set bindscrolltoupper and bindscrolltolower in scroll-view
Set bindscrolltoupper and bindscrolltolower in scroll-view, and then write the trigger event in js corresponding method. [Note, you must set the height of scroll-view when using this mode. I 100% don’t know why the setting has no effect. It is recommended to use 100vh]

<scroll-view scroll-y = true bindscrolltolower="loadMore" bindscrolltoupper="refesh"> .......... </scroll-view>
js
onPullDownRefresh: function() { // Do something when pull down. console.log('刷新'); }, onReachBottom: function() { // Do something when page reach bottom. console.log('circle 下一页'); },
