各位大佬好,
楼主也是一位计算从业人员,写代码、用脚本也好多年了。脚本也只是简单应用,脚本问题还是会经常来这儿搜索学习。
关于控制光标位置的方法(tab和backspace方法)其实一早就用过,但是win10上不好使,一直没有去研究。
上周工作中又用到了,想着这次一定好好研究研究,然后翻遍了互联网,发现也没有好的方法,不过倒是学习到了很多其他技巧,然后自己应用到光标的获取和控制上,效果还行。
发出来分享给大家,顺便问问还有没有更好法。
另外,这个脚本启动时会打印// 2>nul这一行,大家有没有好的办法优化一下?- // 2>nul & @goto :batch_start
- /*
- :batch_start
- @echo off
- setlocal
- setlocal ENABLEDELAYEDEXPANSION
-
- rem 必须执行的步骤,初始化c#辅助程序
- call :init_cursor_control
-
- rem 下面的代码主要是为了清除屏幕第二行输出的// 2>nul,会有闪烁。如果觉得不好,可以删掉,或者用cls清屏。
- rem 但是cls清屏会把屏幕所有都清掉,包括非本脚本输出内容。
- call :get_cursor_info Current_X Current_Y Max_X Max_Y
- set /a Init_Y=%Current_Y% - 1
- call :set_cursor_position 0 %Init_Y%
- call :get_back_space BackSpace
- set "BlankSpace="
- for /l %%a in (1,1,%Max_X%) do set "BlankSpace=!BlankSpace! "
- echo %BackSpace%%BlankSpace%
- set /a Init_Y=%Current_Y% - 2
- call :set_cursor_position 0 %Init_Y%
-
-
- rem 脚本加在下面位置,其他地方不要动

- call :get_cursor_info Current_X Current_Y Max_X Max_Y
