function clearForm(formName) {
var form = document.forms[formName];
for (i = 0; i < form.elements.length; i++) {
if (form.elements[i].nodeName == "input") { // for input

} else if (form.elements[i].type == "text" || form.elements[i].type == "hidden") { // type = text || hidden
form.elements[i].value = "";
} else {
// No clear of input type=file
}
} else if (form.elements[i].nodeName == "select") { // for select
form.elements[i].options[0].selected = true;
} else if (form.elements[i].nodeName == "textarea") { // for textarea

}
}
