Hi all!

I’m trying to do something a little tricky. Can anyone help:

I want to combine two functions of two different script with the click of a single link. Ie, call a function using a link that itself calls other functions...

The first script is mootools driven and is a panel that toggles when you click a link.
Script (HEAD):

<script type="text/javascript" src="mootools.svn.js"></script>
<script type="text/javascript">
window.addEvent('domready', function(){
var mySlide = new Fx.Slide('top-panel');

$('toggle').addEvent('click', function(e){
e = new Event(e);
mySlide.toggle();
e.stop();
});
});

</script>
Link to toggle panel (BODY):

<a href="#" id="toggle">Click here to toggle panel</a>
The second script is an ajax loader (HEAD):

<script type="text/javascript">

fileref=document.createElement('script')

fileref.setAttribute("src", file);
}
else if (file.indexOf(".css")!=-1){ //If object is a css file
fileref=document.createElement("link")
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", file);
}
}
if (fileref!=""){
document.getElementsByTagName("head").item(0).appendChild(fileref)
loadedobjects+=file+" " //Remember this object as being already added to page
}
}
}

</script>
The page called into the div is by (BODY):

<a href="javascript:ajaxpage(‘content_to_call.html', 'area_to_load');">test</a>

<div id="area_to_load"></div>

SO, what I want to do is make a single link that, when clicked, both loads a page into the ‘area_to_load’ div and also toggles the panel. In fact, to make it even more tricky I want lots of links which both load different content into ‘area_to_load’ (depending on the link clicked) and also toggle the panel… if that makes sense?

I have tried
<a href="javascript:ajaxpage(‘content_to_call.html', 'area_to_load');" id="toggle">Click here to toggle panel</a> but did not work :-(

I really cant figure out how to do it so I would be really greatful for any help anyone can give.

Thanks

Matt

Do you have a live demonstration of this?

That doesn't make a lot of sense to me simply because, and it can be done, when it's done, say you click on one link to load one thing into the 'area_to_load' division. When you do that, it also toggles the 'top-panel' division. Click on another one, and it again toggles the 'top-panel' division. So, if you are following, there is no logical sequence to the toggle of 'top-panel'. If it's open, it closes. If it's closed, it opens. The only controlling factor is whether or not it was open or closed when a link that toggles it is clicked.

But, if you are willing to live with that (I guess it could be OK, depending upon the layout, and more importantly, the content):
