The logic of the page is to request the back-end data first, and then backfill it to the page. But in the implementation, I found that the data was asynchronous. I want to ask the boss how to modify it. Here is the related code.
let data = JSON.parse(result);
this.Header = data.Header
Print variables out in order. As a result, the data is not backfilled into the page. Thank you very much for your help.
