Utilizing ng-pattern to validate a regular expression. The pattern must include 3 letters and 2 numbers in a group.
For example: G-31SSD or G-EEE43
Currently, the pattern only matches the second example.
ng-model="newGroup.groupCode" ng-pattern="/^\b[gG][-][a-zA-Z]{3}\d{2}\b$/"
Is there a way to adjust it to match both conditions, or can I write an OR condition for ng-pattern?
To create a regular expression pattern, use the alternation symbol | along with a non-capturing group denoted by (?:...)
The regex pattern to match either a letter followed by 2 digits or 2 digits followed by a letter starting with 'g' or 'G' is:
^[gG]-(?:[a-zA-Z]{3}\d{2}|\d{2}[a-zA-Z]{3})$
Check out the demo here
^[gG]-\d{2}[a-zA-Z]{3}$|^[gG]-[a-zA-Z]{3}\d{2}$
Another option is to try:
^[gG]-(?:(?:\d{2}[a-zA-Z]{3})|(?:[a-zA-Z]{3}\d{2}))$
You can use this pattern to meet both conditions. Simply employ the | operator, which will match both types. Check out the demo here.
