Error with my script in IE.

[davef101]

heres my onBlur function to change the first letter of each word to uppercase.

function toUpper(value) {

var pattern = /(\w)(\w*)/; // a letter, and then one, none or more letters

var a = value.split(/\s+/g); // split the sentence into an array of words

for (i = 0 ; i < a.length ; i ++ ) {
var parts = a.match(pattern); // just a temp variable to store the fragments in.

var firstLetter = parts[1].toUpperCase();
var restOfWord = parts[2].toLowerCase();

a = firstLetter + restOfWord; // re-assign it back to the array and move on
}

value = a.join(' '); // join it back together
return value;
}

It works fine in fireFox, but in IE if the form fields are empty, i get this error:

### ERROR ###
'1' is null or not an object at line 'var parts = a.match(pattern);'
### ERROR ###

The script carries on with the error, but i need to know how elimate this bug.

Thanks.

ok problem fixed .. added:

if (value == "") { return value; }

as the first line of the function.
