The demo gives an error

[chinesedfan]

Demo examples > scroll > vue: https://jsplayground.taobao.org/vueplayground/ca7bef18-ce30-4e00-9a41-746b8646348b.

Is it working in progress or did I miss something?

@chinesedfan hi there, the demo just works fine in my phone. Please provide more details about your environment such as device model(android/iOS), bindingx/weex version...

[chinesedfan]

@Rowandjj The weex page is correct. But the web page is not.

I just open a Chrome tab to visit the link and got the above error in the console.

@chinesedfan well, I see. It's a copy-paste mistake :(
the onappear method is declared but not implemented...
I have fixed that:

@Rowandjj Great! Please update the link in README.md and close this issue.

done.
thanks very much:)
