RegExp validation

The following vbscript sub checks that a value has a specific format:
first 3 characters are alphabetic: anything from a - z. The last 4
characters are numeric: anything from 0 - 9

Sub CheckString(val)
Set VerifyValue = New RegExp
VerifyValue.Pattern = "^[a-z]{3}\d{4}$"
VerifyValue.IgnoreCase = True
If VerifyValue.Test(val) = False Then
alert("Please enter a valid number.")
End If
End Sub

How do I write this in JavaScript?

function CheckString(val) {
if (!/^[a-z]{3}\d{4}$/i.test(val)) alert("Please enter a valid
number.");
}

Man that was fast!

And it works perfectly too! Thanks.

or, to return boolean value

function CheckString(val,message){
return/^[a-z]{3}\d{4}$/i.test(val)||!!alert(message);
}
