can i use "selector" without id or class for special tags? ex. "iframe"

Question

hi...
i have too much iframe on my html page without any id or class
is there any way to select iframe tags automaticly... or some tricks...?

Answer 1

document.getElementsByTagName("iframe")[index]

Answer 2

document.querySelectorAll("iframe")[index];

... also works, and in JQuery, something like:

$("iframe").get(index);

... should do the trick ^^
