: if i set an ID on a element i can reach it with window.id or id or

: document.all.test_input

: but if i put a form over it -><form><input type="text"
id="test_input"></form>
: i can't reach the INPUT Element with window.test_input or direct with
test_input. -->error: test_input undefined
: only document.all.test_input works
: the same shows up with select element, or other Elements which can be sent
by form.
: why?
: i thought id is a unique identifier which can be easily reach per ID or
window.ID

document.getElementById("test_input")

: the second problem i have is putting an ID on iframe
:
: <iframe id="test_iframe"></iframe>
:
: alert (test_iframe) shows up that the ID is set..--> Object
:
: but the property test_iframe.src is undefined. alert (test_iframe.src) ->
undefined
: but document.all.test_iframe.src is defined. alert
(document.all.test_iframe.src) -> ""
:
: so what i want to say is, i can only set the src property of an iframe
with document.all.IFRAME_ID.src=..
: why not with IFRAME_ID.src;

1. You're not providing src in the iframe example above.
2. document.getElementById("test_iframe").src perhaps?
