calling scripts inside body tags?

[drmbdrummer]

i wrote my entire webpage using the document.write command, but now i need to create a functino inside the body tags, is this possible, and if so how on earth is it done, thank you

May I suggest that you don't write your entire page in JavaScript, if you do that then people with JavaScript disabled or people using non-visual browsers cannot "view" your page.

In any case, here's how it's done:

document.write('<script type="text/javascript"><!--');
document.write('a_function();');
document.write('</sc'+'ript>');

My preferred method (escaping closing <script> tag):

document.write('<script type="text/javascript"><!--');
document.write('a_function();');
document.write('//--><\/script>');

I noticed.

What's up with the HTML comments?

[David Harrison]

It's to hide the script for browsers with JavaScript disabled. I would have thought that you would have known that one Charles.

Then why are you using it inside of a "document.write()"?

[David Harrison]

Good point, habit I suppose. It's good practice for when it is needed though.

<script type="text/javascript">
<!--
document.write('<script type="text/javascript"><!--');

...

document.write('// --></script>');
// -->
</script>

Now, SGML has a lot of rules the browsers ignore and one of them is the permissibility of nested comments. And the browsers that do not understand the SCRIPT element are the ones that you can expect to have trouble with nested comments. To such a browser the above looks like...

<!--
document.write('<!--');

...

document.write('// -->');
// -->

[David Harrison]

Best just to stick with this then:

document.write('<script type="text/javascript">');
document.write('a_function();');
document.write('</sc'+'ript>');

or:

document.write('<\/script>');

A good spot Charles. How are you not a moderator yet?
