[RESOLVED] Regexp help

[david8787]

I have the following code but it always returns false with usernames that should be ok, like 'tttt'.

function isUsername(username)
{
	var usernamePattern = new RegExp("/^[a-zA-Z0-9_]{3, 25}$/");

if (!usernamePattern.test(username))
{
	alert ('pattern:' + username);
	return false;
}

return true;
}

What am I doing wrong?

I changed the code to the following and it seems to work.

function isUsername(username)
{
	var usernamePattern = /^([a-zA-Z0-9_]){3,25}$/;

if (!(usernamePattern.test(username)))
{
	return false;
}

return true;
}
