Hi,
i have to add a company established date field in CRM form with the following requirement.
Hi Siva,
You can use regex validation for year to address here are some of the links which may be helpful to you.
1. https://www.regextester.com/93651
2. https://www.py4u.net/discuss/340793
3. https://stackoverflow.com/questions/17547710/javascript-regex-validate-years-in-range
If you can get exact regex using above link then you can just check with Regex.Match to address your requirement.
If not then you can perform below operation-
1. Check Regex.Match with 4 digit number ^[12][0-9]{3}$ ( Validate from 1000 - 2999)
2. After above regex check you can validate it with current year using -> new Date().getFullYear()
3. Code will be some how as below,

} else { alert("This is not a valid year"); } }Hope this help you, If it is helpful pls mark as Verified Answer, which will help others as well. Thanks!
