回显后转到命令

Question

是否可以在回声后立即使用goto而不创建新行？

set /p talk=">"
if /i "%talk%"=="hello" echo Hello!
if /i "%talk%"=="how are you?" echo Good thanks!
if /i "%talk%"=="who are you?" echo I am COM.
echo That statement was not recognized.
goto 1

我可以这样做，以便在它回应其中一条响应行之后开始它并且如果你输错了它说“那个语句没被识别”。并转到1？

有多种方法可以批量跳转：

• 制作代码块

    @ECHO OFF &SETLOCAL
    :first
    set /p "talk=>"
    if /i "%talk%"=="hello" echo Hello!
    if /i "%talk%"=="how are you?" echo Good thanks!
    if /i "%talk%"=="who are you?" (
        echo I am COM.
        goto:first
    )

---

• 使用＆符号&
连接命令

    @ECHO OFF &SETLOCAL
    :first
    set /p "talk=>"
    if /i "%talk%"=="hello" echo Hello!
    if /i "%talk%"=="how are you?" echo Good thanks!
    if /i "%talk%"=="who are you?" echo I am COM. &goto:first

您需要始终使用目标跳转标签，例如。 :first。

set /p talk=">"
if /i "%talk%"=="hello" echo Hello! & goto :skip_error
if /i "%talk%"=="how are you?" echo Good thanks! & goto :skip_error
if /i "%talk%"=="who are you?" echo I am COM. & goto :skip_error
echo That statement was not recognized.
goto 1
:skip_error
