У меня есть старый код, который использует iFrames. Код хорошо отображается на экране, однако, когда я пытаюсь манипулировать некоторыми элементами с помощью JavaScript, он не может их найти.
Например, он говорит, что таблица пуста (но я смотрю на экран).
Как я могу манипулировать HTML, когда он находится в iFrame?
UPDATE:
Я попробовал этот код JavaScript:
alert(window.frames['iframe_layer1'].document.forms['pagectrls'].elements['ptObj_listbox2'].innerHTML);
Я получил следующую ошибку от FireBug:
window.frames.iframe_layer1.document.forms.pagectrls.elements.ptObj_listbox2 не определен
Вот вывод кода из iFrame:
