[Javascript] Validation

[Peter Brunone]

Something I whipped up for the occasion:

<SCRIPT LANGUAGE="JavaScript">

var myString = "whatever'sinthestring";

var myAlphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

var i = 0;

while(i<=myString.length) {
    if(myAlphabet.indexOf(myString.substr(i,1)) < 0) {
        i = myString.length;
        alert("This string has non-alphabetical characters in it"); 
        // or whatever you like
        }
    i = i + 1;
    }
</SCRIPT>
