你好，
我有一列是示例描述，并且在我想从所有行中删除的描述之前总是有一个〜数字。 只有一排有“~”。 例如。
样本：
126：说明AB
291：说明 XYZ
~619: 说明
是否有 JSL 脚本可以从 Sample 列中的所有行中删除“~”、前 3 位数字和“:”（包括空格）？ 我正在查看的数据前面总是有一个 3 位数字以及 : 和空格。 问题是从其中一行中删除 ~ 。
感谢帮助
乔什
这是一种方法，本质上是使用“:”作为分隔符，从最后一个“单词”中删除前导空格。 还有其他方法，包括正则表达式。

);你好@火腿,
由于您想要保留的部分始终与字符串的其余部分由空格分隔，因此您可以使用如下所示的重新编码公式来保留所有“单词”，除了第一个（这是字符和数字的混合但不以空格分隔）。 您可以简单地将“Column 1”列名称更改为包含样本描述的列名称。
Recode(
:Column 1,
{Word(
[2 -1],
_rcNow,
Get Whitespace Characters() ||
Get Punctuation Characters( Exclude Chars( "'-" ) ),
Unmatched( _rcNow )
)}
)
希望这个其他选项对您有所帮助，
有很多不同的方法可以做到这一点，下面是一个使用正则表达式的选项
Regex("126: Description AB", "~?\d{3}: (.+)$", "\1");
Regex("291: Description XYZ", "~?\d{3}: (.+)$", "\1");
Regex("~619: Description", "~?\d{3}: (.+)$", "\1");
