Indiscriminate JavaScript approach to selecting the first valid input field on a page:

function SelectFirstInput() {
    var bFound = false;
    for (f = 0; f < document.forms.length; f++) {
        // for each element in each form
        for (i = 0; i < document.forms[f].length; i++) {
            // if it's not a hidden element
            if (document.forms[f][i].type != "hidden") {
                // and it's not disabled
                if (document.forms[f][i].disabled != true) {
                    // set the focus to it
                    document.forms[f][i].focus();
                    var bFound = true;
                }
            }
            // if found in this element, stop looking
            if (bFound == true)
                break;
        }
        // if found in this form, stop looking
        if (bFound == true)
            break;
    }
}
