Use description:
A form
Two lines
The first line has a " , -" icon, " " indicates the line harvest after the line, "-" means expansion
The function is triggered when I icon OnClick.
It turned out that I used a 20-line code when I wrote this function. Now I am 8 lines. I originally implemented it in the future. Now it is a loop iteration. Note The optimization of code is endless, maybe I am really weak when I write 20 lines, maybe now I don't want to go, but I am sure, that is, I am progressing. Finally, I want to say: Don't be in the current achievement, and it is endless.
