I'm relatively new at JavaScript, but as far as I have gone it seems pretty similar to most other OO programming languages. Relatively. Different syntax, same concept. But for some reason, whenever I try to activate a function by clicking on a link, it won't work.

Code: 
<script language="JavaScript" type="text/javascript">

//more code here...

function testfunction()
{
	alert("this works");
}

</script></head> <body bgcolor="454549" leftmargin="0">
<script>
var lastsubmitted
</script>
<a class="anchorStyle" onMouseDown="alert('this works')">Slideshow</a><br>
<a class="anchorStyle" onMouseDown="testfunction()">Next</a><br>

I know it's not my HTML, because the straight out "alert('this works')" link (the first one) works perfectly well, but as soon as i put it in a function it refuses to go. What am I doing wrong?

Apologies if this is hopelessly pathetic. As I said, I'm relatively new at JS.

Have you tried using "onclick" instead of "onMouseDown"?

Hope this helps,
Dan

It's not working because and anchor already HAS a onclick action! If you change it to:
Code: 
<a class="anchorStyle" href="javascript:alert('this works')">Slideshow</a><br>
<a class="anchorStyle" href="javascript:testfunction()">Next</a>
it will work. Or you could change the anchor tags to some other kind of that that does not normally have an onclick action.

For me the code works both with onMouseDown and onClick, but I'd rather use onClick or href, otherwise the right mouse button will also activate the function.

The code you posted works fine for me. Something tells me we're not getting the whole story.

Tracy, are you saying you can't have an onclick event in an anchor? I'm not so sure about that...

actually, tracy, the first one works fine, even in an onClick or onMouseDown event inside an anchor tag.

it's only when i call the function.

adam, i've made a bare bones version of my current page with the code i've posted (which is obviously missing a lot of other stuff) and you're right, it works. also, that function was obviously meant to do other stuff.

hmm. wonder what's gone wrong?

by the way, tell me if i'm wrong, but javascript is compiled line by line, right? so if, say, in a function that had an invalid call or something, everything up to that point would be compiled and occur?

Perpaps the problem is in the other code.
Remove the additional code and test it. If it works, add in more until you narrow down the problem.

Also, take a look at the javascipt errors (if any): In IE, double click on the icon in the bottom, left corner of the status bar. In Firefox, use the javascript console.
