SharePoint自定义列表日期和时间验证

Question

我有一个自定义列表，我试图限制数据输入的有效日期和时间。 我当前的列验证适用于星期一，星期三或星期五的星期几。它看起来像这样：

=CHOOSE(WEEKDAY([Requested date for approval]),FALSE,TRUE,FALSE,TRUE,FALSE,TRUE,FALSE)

我正在试图找出要添加的语法，它必须在那些日子的上午8点到中午12点之间。

非常感谢任何帮助。

Answer 1

您可以使用AND语句来包含第二个条件

=AND(CHOOSE(WEEKDAY([Requested date for approval]),FALSE,TRUE,FALSE,TRUE,FALSE,TRUE,FALSE),
  AND(
    [Requested date for approval]-INT([Requested date for approval])*24 >= 8,
    [Requested date for approval]-INT([Requested date for approval])*24 <= 24
  )
)

我承认，我从未听说过CHOOSE功能，但时间计算是基于Microsoft的信息

转换时间 要将小时从标准时间格式转换为十进制数，请使用INT  功能

Column1       Formula                           Description (possible result)
10:35 AM      =([Column1]-INT([Column1]))*24    Number of hours since 12:00 AM (10.583333)
12:15 PM      =([Column1]-INT([Column1]))*24    Number of hours since 12:00 AM (12.25)

修改

要计算星期几，您可以使用TEXT函数返回星期几（即星期一）

=TEXT(WEEKDAY([ColumnName]), "dddd")

它不会很漂亮，但你可以使用一系列AND逻辑运算符

=AND(
  TEXT(WEEKDAY([Requested date for approval]), "dddd") = "Monday",
  AND(
    TEXT(WEEKDAY([Requested date for approval]), "dddd") = "Wednesday",
    AND(
      TEXT(WEEKDAY([Requested date for approval]), "dddd") = "Friday",
      AND(
        [Requested date for approval]-INT([Requested date for approval])*24 >= 8,
        [Requested date for approval]-INT([Requested date for approval])*24 <= 24
      )
    )
  )
)

=IF(
  AND(
    CHOOSE(
      WEEKDAY([Requested date for approval]),FALSE,TRUE,FALSE,TRUE,FALSE,TRUE,FALSE
    ),
    ([Requested date for approval]-INT([Requested date for approval]))*24>=8,
    ([Requested date for approval]-INT([Requested date for approval]))*24<=12
  ),
  TRUE
)
