convert AS3 in HTML5 Object(root)

Good evening,

I try to convert some animate I made in AS3 to HTML5 . I don't know how to transform the following lines :

this.stop ();



this.O2_btn.addEventListener("click", dioxygene.bind(this));

function dioxygene()
{
	this.Object(root).dioxygene_clp.play();
}

this.glucose_btn.addEventListener("click", glucose.bind(this));

function glucose()
{
	Object(root).glucose_clp.play();
}

this.plus_btn.addEventListener("click", lectureCO2.bind(this));

function lectureCO2 ()
{
if (this.Object(root).glucose_clp.currentFrame==96){
	if(this.Object(root).dioxygene_clp.currentFrame==96){
		this.Object(root).CO2_clp.gotoAndPlay (2);
		this.Object(root).ampoule.gotoAndStop(2);
}
}
}

I just put some this but I think not in the right places.

I'll be happy if some of you can help me, please excuse my bad english.

Best regards
