How can I validate an email address in JavaScript?
(79 answers)
Closed 8 years ago.
I have this regex in JavaScript:
new RegExp('^[0-9a-z._-]+#{1}[0-9a-z.-]{2,}[.]{1}[a-z]{2,}$','i');
and I want to modify it.
The last part of the mail must have a minimum value: 2 chars and no maximum length so I can put mails such as .localhost .paris .thisismyexample ...
How may I do that?
new RegExp('\b[A-Z0-9._%+-]+#(?:[A-Z0-9-]+\.)+[A-Z]{2,}\b','i');

I am trying to extract number from title. I have title like this:
**
Apartment London, 230.400€, 450,00m2
**
I want to extract only this price number (230.400€), can anybody help me with this?
So far my code look like this
\d+\.?\d+(.)
You can include the amount symbol as part of your RegEx:
/\d+\.?\d+(.)€/
Or you can try using Positive lookahead:
\d+\.?\d+(.)(?=€)

How can I make part of regex optional?

Closed 3 years ago.
I have two function in JS that check if a typed input is a valid IPv4.
This is the regex that I got from #Abana Clara from this question: How to validate IP Address on multiple inputs?
var ipformat = /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/;
I would like to add to this regex the possibility to also validate CIDR IPv4 addresses.
Please note that both of the following addresses should be valid:
192.168.1.20
192.168.1.20/24

Phone Number Validation Javascript
Hi I am creating validation for a form using javascript.
I am wanting to check the telephone number field using if statements to ensure it contains a 4 digit area code then a space followed by a 7 digit number.
Any help would be appreciated.
Thanks
So you need to validate something like 1234 1234567
function isValidTel(numberToTest){
var pattern =/^\d{4} \d{7}$/
return pattern.test(numberToTest);
}
