Is there a way that I can determine what type of form field a given form element is?

I would like to do this:

if (form_name.variable_name.type == 'select') {
 alert ('select')
}
elseif (form_name.variable_name.type == 'textbox') {
 alert ('textbox')
}

The type for a (single line) textbox is "text". A <select> element has a type of "select-one" or "select-multiple".
var control = document.forms[form_name].elements[variable_name];
 
if (control.type.indexOf('select')!=-1) {
 alert ('select');
}
else if (control.type == 'text') {
 alert ('textbox');
}
