Question

Following is the requirement of field value should be - else it should generate an error

Format to be only 9 characters with 2 letters, followed by 6 numbers, followed by one letter

Any else value should generate an error message using JavaScript. Can anyone help me in creating regex expression for this.

Examples :

// Common regexs
  var regexEmail = /^([\w]+)(.[\w]+)*@([\w]+)(.[\w]{2,3}){1,2}$/;
  var regexUrl = /^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}([\w]+)(.[\w]+){1,2}$/;
  var regexDate = /^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$/;
  var regexTime = /^([1-9]|1[0-2]):[0-5]\d$/;
  var regexIP = /^((25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.){3}(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])$/;
  var regexInteger = /(^-?\d\d*$)/; **

yep, whqat's wrong with /^([a-zA-Z]{2}\d{6}[a-zA-Z])$/ ? Why you added a space \d{6} ? — Avinash Raj

2 letters, followed by 6 numbers, and Last 1 is letter again. I guess we are not looking at proper length — Salesforce Steps

@NileshMendhe What do you mean by not looking at proper length? As asked 9 characters with 2 letters, followed by 6 numbers, followed by one letter — Rakesh_Kumar

This will help..

/^[ ]*([a-zA-Z]{2}\d{6}[a-zA-Z])[ ]*$/

[a-zA-Z]{2} matches two alphabetic character

\d{6} matches subsequent 6 digits

[a-zA-Z] matches one alphabetic character

Salesforce Steps Over a year ago

should also handle blank space before and after

Rakesh_Kumar Over a year ago

@NileshMendhe actual space added at start and end, but this will make compulsory to have spaces at both ends...Does that comply with requirement?

Salesforce Steps Over a year ago

I mean, it should also match if I put any blank spaces before or after ---- Like we handle using .TRIM() usually. Thnx.

/^([a-zA-Z]{2}\d{6}[a-zA-Z])$/

1st Capturing group ([a-zA-Z]{2}\d{6}[a-zA-Z])
[a-zA-Z]{2} match a single character present in the list below

Quantifier: {2} Exactly 2 times
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)

\d{6} match a digit [0-9]
Quantifier: {6} Exactly 6 times

[a-zA-Z] match a single character present in the list below
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)
$ assert position at end of the string

Check this, show with all explanation.
