当我的一个学生遇到一个问题时，我已经为我的非官方编码类制作了这个代码，每当一个预期的答案被采取时，该过程就会结束任务。我一遍又一遍地检查他的代码，并且不知道问题出在哪里。

echo NOTE: A log file keeps track of all the ping results,as well as time and date,but no personal information is kept,including your IP Address or computer name. To view the log file,type "log" without the quotation marks and hit enter. Similarly,if you wish to clear the log of all data,type "logclr" without the quotation marks and hit enter.

是的，我知道：ping2仍然不存在，因为我还没有将它添加到此代码中，但现有的命令都没有，比如ping1（通过按1），log和logclr。 Logclr，有时，似乎有点＆＃34;刷新＆＃34;屏幕。 感谢您的帮助。我会将这个人的名字添加到某个地方的学分中。也许在网站上（leddevelopment.cu.cc/main/products/led-ping-testor /）。
答案 0 :(得分：1)
不清楚你的意思＆＃34;工作＆＃34;。第二段代码＆＃34;为我工作 - 也就是说，按照我的预期做了。
由于您尚未调用setlocal，因此在早期运行期间进行的任何设置都将保留在环境中。也许这是一个原因。
如果你使用if "%var%"=="string" ...，那么用户进入空格会再次受到保护。您也可以尝试使用if /i ...来区分大小写。
您的if %numb% < 1 goto ping1a无效，<和>是重定向器。您需要分别使用lss和gtr。
如果这些线索无法解决您的问题，请说明发生了什么以及实际发生了什么。
