I need a help to frame a regex to validate a string format in Javascript,
Total length of the string should be between 3 and 30 characters length. First character must be strictly an alphabet. Subsequent characters can be either alphabet or dot or space. Please help.
The following will work for you.
var re = /^[a-z][a-z. ]{2,29}$/i
Regular expression:
^ # the beginning of the string
[a-z] # any character of: 'a' to 'z'
[a-z. ]{2,29} # any character of: 'a' to 'z', '.', ' ' (between 2 and 29 times)
$ # before an optional \n, and the end of the string
\s will match tabs and newlines. Should use an explicit space.
What's going on? Just sent my letter to Regex Santa in the chat room, might see you there? Off to feed the neighbor's cat for a mo.
