Email validation

[4345487]

Hi,

Maybe someone can help me with this email validation

alert( ((/\w+((-\w+)|(\.\w+)|(\_\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z]{2,4}/).test(email)));

I want the values after the dot to no less that 2 and no more that 4 so I use {2,4} if I enter test@test.c it returns false which is what I spected but if I enter test$test.cmmmmmmmmm it returns true what i'm doing wrong.

Thanks in advance

This is the function I use.

function validEmail(address) {
	if (address) {
		if (address.match(/^[^@]+@[^@]+\.[A-Za-z]{2,4}$/)) {
			return true;
		}
	}
}

You're not checking for the end of the string. Your regexp looks to see if there's between 2 and 4 characters after the decimal (which there is). The problem is that it just ignores the rest of the stuff afterwards. Use the following 2 characters to check for the beginning and end of the string:

/[!]^[/!]\w+((-\w+)|(\.\w+)|(\_\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z]{2,4}[!]$[/!]/

On a side note: your profile shows you've asked 37 questions and never given any stars/votes. You've even received 11 in your time here at TT.

I know many people are just unaware of how the system works until it is brought to their attention.

Try this code, it also blocks unwanted characters from the address.

  var re = /^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z]{2,4}$/;
  alert(re.test(value));

This requires minimum two characters before and after the @ and requires 2-4 characters after the .


It's hard to think outside the box when I'm trapped in a cubicle.
