How do you write JavaScript in document.write and have it workproperly?
 

I'll probably be using jquery instead of document.write to write

<script src="http://example.com/script.js">myfunction();</script>

into a div tag, but I can't get it work right in all the browsers. IE
doesnt seem to like it when JS writes JS. Unfortunately I can't modify
something on the serverside to write it from the backend, so I can
only do it with JS.

Any ideas?

If a script declaration has a declared source,
your content "myfunction();" is not executed.

Do not use jquery
till you know enough about javascript to know you better do without it.

<script type="text/javascript">
document.write(
'<script type="text/javascript" src="foo.js"><\/script>');
</script>

If you are lucky, myfunction(); is considered the alternative if the `src'
script cannot be loaded; if not, it will be ignored. The least you need is

<script type="text/javascript" src="http://example.com/script.js"></script>
<script type="text/javascript">myfunction();</script>

provided that `myfunction' is declared in `script.js'.

Of course not. jQuery is bloated junk.

Or you might not know what you are doing.

It escapes me why you want to do that. Either you can modify the source
code, then you can simply write the `script' element as it is. Or you
can't, then you can call myfunction() without including a `script' element
somewhere.

In any case, what you are trying to do is unreliable at best.

TL is usually correct about these sorts of things. I'm not sure if he means
unreliable in the sense that it cannot be guaranteed to work on all
browsers, or under certain unspecified conditions depending on what else
you are trying to do.


Nonetheless, I have been pretty successful at writing javascript to a
document in order to "fake" dynamic code on a static server. Take a look
at:

http://pages.videotron.com/duffym/poetry.htm

and take the poetry exam at the bottom of the page. After you have passed
the exam, it will re-direct you to my "Javascript Phone Poem Generator",
which will take any natural number and then uses the Poem Factor Theorem to
generate a completely new web page which is a rhyming algorithm that
evaluates to the given number. It uses "document.write" to overwrite the
current document, incuding some javascript to take care of the counter. It
works on all browsers I have tested it with (IE 6&7, FF3, Opera, Dillo).

I've done that before and IE didnt like it. Luckily I found a way in
our backend templates to accomplish what we needed, so I dont have to
full around with JS.

Yours wasn't like that then, because that works and IE likes it.

That's nonsense. The former is occasionally useful and the latter is
definitely bad form (and should never be used before the document is
ready, so it isn't a substitute for the former.)

LOL. I'd like to see your replacement that uses innerHTML.
