Calling a javascript function from flash

Bellow is some JavaScript that I'm using for some drop-down menus.
http://www.leigeber.com/2008/11/drop-down-menu/

every thing is working as desired with the static version.

I would like to be able to call the onmouseover and onmouseout functions from Flash or other links on the page.

I'm not that familiar with JavaScript but it looks to me like there are new functions being created for each list element at run-time. How would i create over and out functions for the specific menu elements that i could call from anywhere in the page?

<script type="JavaScript">
var menu=function(){
	var t=15,z=50,s=6,a;
	function dd(n){this.n=n; this.h=[]; this.c=[]}
	dd.prototype.init=function(p,c){
		a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
		for(i;i<l;i++){
			var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
			h.onmouseover=new Function(this.n+'.st('+i+',true)');
			h.onmouseout=new Function(this.n+'.st('+i+')');
		}
	}
	dd.prototype.st=function(x,f){
		var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
		clearInterval(c.t); c.style.overflow='hidden';
		if(f){
			p.className+=' '+a;
			if(!c.mh){c.style.display='block'; c.style.height=''; c.mh=c.offsetHeight; c.style.height=0}
			if(c.mh==c.offsetHeight){c.style.overflow='visible'}
			else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
		}else{p.className=p.className.replace(a,''); c.t=setInterval(function(){sl(c,-1)},t)}
	}
	function sl(c,f){
		var h=c.offsetHeight;
		if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
			if(f==1){c.style.filter=''; c.style.opacity=1; c.style.overflow='visible'}
			clearInterval(c.t); return
		}
		var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
		c.style.opacity=o; c.style.filter='alpha(opacity='+(o*100)+')';
		c.style.height=h+(d*f)+'px'
	}
	return{dd:dd}
}();
</script>

     <div id="staticWrapper" style=" background-image: url(images/menu-bar-bg.png); background-repeat:repeat-x; height:147px; width:100%; z-index:-2; top:0px; position:absolute;">

 runJS(js);

so theoretically i should be able to call `document.links[3].onmouseover();` from an anchor tag as well right?

<a href="javascript:document.links[2].onmouseover();">click here</a>

this dose not work. error: ` document.links[2].onmouseover is not a function.`

any other ideas?

<a href="#" onClick="document.links[2].onmouseover(); return false">click here</a>

assuming document.links[2] HAS a mouseover

No that didn't work either...

the above script seems to be attaching onmouseover functions to the `UL` tags. but i cant figure out how to call those function for the individual tags.

if you would like i cloud email you a link to our testing server.

have you tried the actionscript class ExternalInterface ? you can use it to call javascript from the page its called from. O think this could be used for the purpose you need.

Yes I'm aware of how to call JavaScript functions from flash. getURL("JavaScript:frunctionName()");

my question is based on the above script... what function would i call to activate the on-rollover functionality of each menu item.

thanks,

this javascript should work.

document.getElementById('menu').getElementsByTagName('ul')[0].parentNode.onmouseover();

little explanation incase needed:

document.getElementById('menu').getElementsByTagName('ul')[0].parentNode.onmouseover();

get the menu element, then get all its child ul elements, select the first (index 0) and then get its parent element, then call the mouseover event on it.
So "document.getElementById('menu').getElementsByTagName('ul')" selects all the sub menus, then all thats needed was to select the one you want, in my case i referenced the first, get the parent node and trigger the event.
