What are the considerations of repeater nested programs?

This article mainly introduces the matters needing attention of the repeater nesting program, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Repeater nested loop is a computer term.

Repeater nested program

Varheight=prompt ("Howhighdoyou"

Wantthegrid? (1-10isgood) "," 10 ")

Varwidth=prompt ("Howwidedoyouwant"

Thegrid? (1-10isgood) "," 10 ")

Vara_line

Varnew_window=

Window.open ("/ webmonkey/98/04/files1a

/ grid.html "," looper "," width=400,height=400 ")

New_ window. [XSS _ clean] ln ("AGrid")

For (height_loop=0;height_loop

")

}

After requesting height and width, open a new window, write a header for it, and enter the for loop. The first for loop is set to await line = "". Try not to use this line to do this example and see what happens. After initializing the a_line, the program moves on to the next for loop, and when the width reaches the desired value, the X`s line is created and displayed in a new window. These will occur height times.

Repeater nesting considerations

1. When using loop nesting, the loop control variables for the inner loop and the outer loop cannot be the same.

two。 For the writing of circular nested structure, it is best to use the format of "right indent" to reflect the hierarchical relationship of the loop.

3. Try to avoid too many and too deep loop nesting structures
