"Some years ago I was looking for a job and did a lot of online résumé form filling," Gustavo S. writes.

"One of those many sites had a form that took about a second to uppercase my name when I hit Tab, before putting the focus on the next field.

"That puzzled me. One second to uppercase a single-lined string?! I kept filling the other fields and it continued like this... until it got worse. When I got to the multiline, free text fields to describe past experiences and so forth, I could go for a coffee after every field.

"That was too much for me and I (too late already) looked at the page source.

"The javascript was something like this:

function validate(field)
{
    var A = " abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890,.:!?@#$%¨&*()_+=[]^`Çç{}`^<>\\/|";
    var B = " ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890,.:_____________________________";

    var oldval = field.value;
    var newval = "";

    for (var i=0; i<oldval.length; i++)
    {
        var char = A.indexOf(oldval.substr(i, 1));
        newval = newval + B.substr(char, 1);
    }
    field.value = newval;
}

"Somehow I felt glad that they didn't call me."
