I have following now.
regex=^[0-9]{6}$
this is working for starting 0 to 9 and for 6 and 7 digit number.
Please suggest how can i add for 5, 6 and 7 digit numbers.
use the range form of the { }
operator
^[0-9]{5,7}$
Range inside of {N,M}
is demarcated with a comma and translates into a string with length between N
and M
inclusive.
This is notably different from the [ ]
operator which is to describe a character group and uses the -
symbol to demarcate its ranges.
^[0-9]{5,7}$
should do the job for you if I understood your question correctly also your regex ^[0-9]{6}$
will match exactly 6 digits not 6 or 7 as you stated.
