Patterns (Regex) - Simple – Softools

The ReGex pattern allows us to implement Validation into your Text Field. Validation allows you to restrict what data is put into your Text box. For instance, we can restrict the user to characters ranging from A to H or to lowercase characters exclusively etc.

Some Common Examples:

Alphanumeric without Spaces

/^[a-zA-Z0-9]*$/

Whole Numbers

/^\d+$/

UpperCase Letters with white space

[A-Z\s]+

LowerCase Letters with white space

[a-z\s]+

Colour HexCode

Colour Hexcode "^#(?:[0-9a-fA-F]{3}){1,2}$

Use Case Examples

Match Any Email Address from a Specific Domain
Usage Example	Match any email address from the domains hotmail.com, and gmail.com.
Regex	(\W\|^)[\w.\-]{0,25}@(hotmail\|gmail)\.com(\W\|$)
Notes	Any character that isn't a letter, number, or underscore is represented by \W. The regex won't match characters before or after the email address because of this. ^ Allows the regex to match the address if it occurs at the start of a line, without any preceding characters. [\w.\-] matches any word character , a period, or a hyphen. {0,25} specifies that characters from the previous character set may appear before the @ symbol in a range of 0 to 25.

Match Word or Phrase
Usage Example	Match any word or phrase in the following list: Softools Gridfields Zero Code
Regex	(?i)(\W\|^)(Softools\|Gridfields\|Zero\sCode)(\W\|$)
Notes	(?!) enables the case-insensitive matching Because the \| symbol denotes a "or," the regex matches any of the words in the list. \s Utilize this character to denote the separation of words within a phrase.
