Ragic 透过正规表示法提供了简单的输入检查机制,在知道如何以正规表示法表达后,就可以阻塞用户保存不符合规则的数据。
如果不熟悉正规表示法,可以从范例里选择,或是搭配条件公式运行。
在输入检查小帮手输入需求,让 AI 帮你生成正规表示法。需求建议简短明确,如果要限制字段值前面 3 位是数字后面 3 位是英字母,就只填入“前面 3 位是数字,后面 3 位是英字母”。
生成 Regex 句法后,就会自动生成正规表示法。接着单击下拷贝到输入检查,即可将句法拷贝到输入检查中。
设置完成后记得保存设计。
你可以在输入检查中利用正规表示法来检查输入的字数。例如正规表示法“^.{6,7}$” ,将会检查此字段的输入值,最少要输入六个字,最多七个字。其他字数的输入限制,你也可以只限制最多字数,例如“^.{0,7}$”(最多七个字);或是“^.{6,}$”(最少六个字)。
也可以在输入检查使用正规表示法的语言范围编码来确保用户所填入的数据为特定的语言。例如想要确保输入的内容为 Cyrillic(西里尔字母)语言,可以用“\u0400-\u04FF\u0500-\u052F”来表示。下方为各语言的范围代码参阅,你也可以从这个网址来找到更多的语言代码。
