javascript 预填充URL备份

Posted 2021-05-04

/*
* Getting a prefilled URL is like sending a bus out to get passengers
* The bus is the formResponse
* The passengers are the formItems (each of which has an ID and type)
* They get on the bus in a particular order
* Once on the bus, it drives to a parking space
* Once many buses arrive, it becomes a parking lot--- this is the testSheet
