Very Simple JavaScript Question

01-07-2005

Let us say I have a JavaScript function called get_one() which returns a
one. I am not entirely sure if the returned value can be accessed only by
another function. Is there a way of doing something like the following?

<font size=get_one()>Hello World</font>

Must I use document.write?

Thanks and sorry about the low level of this question,
Roy

The value returned can be accessed by any other function or operation as
long as it's within scope.

Yes, though which version of HTML are you using? Presumably it's an old
one, seeing as you've got a <font> element.

That's what I imagined. I need to fetch a URL for an image. Does it mean I
have to write a block, assign it an ID and then overwrite it with
document.write? I have done this with <div> before but what if I have a
very large <table>...</table> block?

I simplified a much larger problem. I don't use <font>

Thanks,

My problem is now a little different. If I use document.write to write HTML
that has JavaScript within it, the JavaScript does not work. Is there a way
around this?

Maybe...:

<script type="text/javascript>
function get_one() {
x = 1;
return x;
}
</script>

<body onload="document.getElementById('foo').style.fonts ize=get_one();">
<div id="foo">Hello World</div>
</body>

Thanks guys!

I have already done this in PHP (had to learn it as well to get it done)
because I imagined it would be impossible with _simple_ JavaScript.

Took longer, but at least I learned something new...

Maybe, but it sounds like you're trying to solve something in a wrong
way. What are you trying to do in the first place?

This would create a global variable, x, when I doubt that's required (nor
desired). Always use the var keyword.

I'd have thought

return 1;

would be simpler.

The 's' in fontsize must be capitalised.

Finally, '1' wouldn't be a valid value to be assigned to the fontSize
property; you still have to follow the CSS specification and include units
for length values (or use one of the other accepted value types).
