Actionscript-Javascript Interaction

I needed to make a html file with embedded flash that had the javascript on the html page triggering events in the flash and vice versa. This is the final solution which was used.

HTML

<a id="BM" href="bermuda.html" onMouseover="asMouseOver(this.id)" onMouseout="asMouseOut(this.id)">Bermuda</A>

Actionscript

• COLOURWANG = using prototype to define the clearRGB function for the mouseOut
• FUNCTIONWANG = defines the mouseovers and mouseouts colour changes
• COUNTRYFUNCTIONWANG = defines the rollovrs and rollouts for the mouseovers and mouseouts hover captions functions (for each specific movieclip)
• WORDWANG = defines the hover caption function
• EXTERNALINTERFACEWANG = externalinterface callback that allows Actionscript to access the Javascript functions (by declaring them in advance)

import flash.external.ExternalInterface;

// COLOURWANG!

Color.prototype.clearRGB = function(){
     this.setTransform({ra:100, rb:0,ga:100,gb:0,ba:100,bb:0,aa:100,ab:0});
}

// FUNCTIONWANG!

function countryOver(id) {
	var newColor = new Color(eval(id));
	newColor.setRGB(0x2A87AC);
}
function countryOut(id) {
	var newColor = new Color(eval(id));
	newColor.clearRGB();
}
function countryOverHTML(id){
	ExternalInterface.call("countryMouseOver",id);
}
function countryOutHTML(id){
	ExternalInterface.call("countryMouseOut",id);
}

// COUNTRYFUNCTIONWANG!

BM.onRollOver  = function()  {
	countryName(true, "Bermuda", this);
	countryOver("BM");
	countryOverHTML("BM");
	this.onRollOut = function() {
		countryName(false);
		countryOut("BM")
		countryOutHTML("BM");
	};
}; 

// WORDWANG!

countryName =  function (showCaption, captionText, bName)  {
if (showCaption) {
	_root.createEmptyMovieClip("hoverCaption", this.getNextHighestDepth());
	cap.desc.text = captionText;
	cap._width = 8*cap.desc.text.length;
	cap._alpha = 75;
	hoverCaption.onEnterFrame = function() {
		cap._x = _root._xmouse;
		if ((cap._x-(cap._width/2))<0) {
			cap._x = cap._width/2;
		}else if((cap._x + (cap._width/2))>330){
			cap._x = 330 - (cap._width/2);
		}else{
		}
		cap._y = _root._ymouse-15;
		cap._visible = true;
	};
} else {
	delete hoverCaption.onEnterFrame;
	cap._visible = false;
}
};

// EXTERNALINTERFACEWANG!

var method1:Function = countryOver;
var method2:Function = countryOut;
var instance:Object = null;
ExternalInterface.addCallback("textMouseOver", instance, method1);
ExternalInterface.addCallback("textMouseOut", instance, method2);
