I need to validations in place for my Angular app on an email field. The restrictions are: 1. The email should be of valid format (Angular's built in validators would take care of this) 2. The email should have a fixed '@abc.com' part. The field should error out in case someone enters another domain.
I'm thinking I should use ng-pattern, but am not sure how to go forward with it. TIA!
/^[-_A-Za-z0-9\.]+@abc\.com$/g
Quantifiers :
+ Between one and unlimited times, as many times as possible, giving back as needed [greedy]
-_ a single character in the list -_ literally
A-Z a single character in the range between A and Z (case sensitive)
a-z a single character in the range between a and z (case sensitive)
0-9 a single character in the range between 0 and 9
@abc matches the characters @abc literally (case sensitive)
\. matches the character . literally
com matches the characters com literally (case sensitive)
$ assert position at end of the string
g modifier: global. All matches (don't return on first match)
A regular expression is quite heavy machinery for this purpose. Just split the string containing the email address at the @ character, and take the second half. (An email address is guaranteed to contain only one @ character.)
But if anyway you want to use it:
@(.*)$
This will match with the @, then capture everything up until the end of input ($)
