Implement pull-up refresh function based on Vue framework vux component library

Recently, the company has been developing an app and selected a vux component library based on the Vue framework. Now we will summarize the pitfalls encountered in implementing the pull-up refresh function:
1. Problem: Only refresh once, solution: you need to manually reset the status yourself
= ‘default'，
2. Problem: Cannot scroll, solution: Because keep-alive cache is enabled, you need to set it

activated () {
 this.$()
}

If it doesn't work yet, please execute the following code after obtaining the background data

this.$nxtTick(() => {
    this.$()
   })

Post the code for the entire page.
