function ajax_example_simplest_callback($form, $form_state) {
//... do my stuff here
//normally I would return only the form bit for replacing a single wrapper
//declared in the trigger element, like this:
return $form['element_to_be_replaced_blahblah'];
}
Apakah mungkin untuk mengembalikan lebih dari satu bentuk bit dalam fungsi panggilan balik yang memberitahukan kerangka kerja AJAX yang $form['element_to_be_replaced_1']
harus diganti <div id="replace_div_1">
dan $form['element_to_be_replaced_2']
harus diganti <div id="replace_div_2">
?
