Checkbox changed by browser after running javascript

[NnlGggTuqPvt]

I have a form with a checkbox. Using MSIE, the user marks the checkbox,
submits the form and gets his result. Then he uses the browsers back
button to return to the form.

Here I have a
checkbox=document.getElementById('ch1');
alert(checkbox.status);

This alert pops up and says "false". I can see that the checkbox is not
activated. Then I click "ok" to the alert and then the checkbox is
checked. I.e. the browser fills in the previous values _after_
javascript processing is done.
How can I determine the checkbox status with javascript?

When do you activate the above script - onload? in a script element in
the page?

When - onload? during load?

I didn't ever hear about a "status" property. Why don't you use "checked"?

Of course I don't check it onload, the script is inside the page
between </body> and </html>

Why not? It will likely fix your problem.

the script is inside the page
between </body> and </html>

That is invalid markup, an HTML element can only contain head and body
elements:

<!ENTITY % html.content "HEAD, BODY">

<URL:http://www.w3.org/TR/html4/struct/global.html#edef-HTML>


If the browser stumbles across a script element as a child of the HTML
element, you are at the mercy of error correction.

I think it's not important what I use. When the alert pops up, the
checkbox is not checked. The browser fills the check mark after the
script ran.

Judging by the fact that "of course I don't" is not a reasonable answer,
I'm guessing that you don't understand that "onload" means using the
body's onLoad event handler, so that the code is executed after the page
has completely loaded.

Code appearing after the body is invalid HTML.
