Suppose I want only digital/numeric value (No Special character or alphabet)
So, the regular expression will be ^[0-9]
If I want a fix length of 6, what regular expression I should use?
Example: 555333, 111222
Try ^[0-9]{6}$
^
beginning[0-9]
digit 0 to 9 (alternatively you could use [\d]
){6}
appears exactly 6 times$
end of string
