propaganda flutuante

[Andre Summers 0]

Eu usei o seguinte código para construir uma propaganda flutuante:

 

<script type="text/javascript">

	function closeDiv() {
		document.getElementById('floatLayer').style.left = "-1000";
		return false;
	}

	window.onerror = null;

	var topMargin = 135;
	var slideTime = 1000;
	var ns6 = (!document.all && document.getElementById);
	var ie4 = (document.all);
	var ns4 = (document.layers);

	function layerObject(id,left) {
		if (ns6) {
			this.obj = document.getElementById(id).style;
			this.obj.left = left;
			return this.obj;
			}
		else if(ie4) {
			this.obj = document.all[id].style;
			this.obj.left = left;
			return this.obj;
			}
		else if(ns4) {
			this.obj = document.layers[id];
			this.obj.left = left;
			return this.obj;
			}
		}

	function layerSetup() {
		floatLyr = new layerObject('floatLayer', pageWidth * .2);
		window.setInterval("main()", 10)
		}

	function floatObject() {
		if (ns4 || ns6) {
			findHt = window.innerHeight;
		} else if(ie4) {
			findHt = document.body.clientHeight;
		   }
		}

	function main() {
		if (ns4) {
			this.currentY = document.layers["floatLayer"].top;
			this.scrollTop = window.pageYOffset;
			mainTrigger();
			}
		else if(ns6) {
			this.currentY = parseInt(document.getElementById('floatLayer').style.top);
			this.scrollTop = scrollY;
			mainTrigger();
		} else if(ie4) {
			this.currentY = floatLayer.style.pixelTop;
			this.scrollTop = document.body.scrollTop;
			mainTrigger();
		   }
		}

	function mainTrigger() {
		var newTargetY = this.scrollTop + this.topMargin;
		if ( this.currentY != newTargetY ) {
			if ( newTargetY != this.targetY ) {
				this.targetY = newTargetY;
				floatStart();
			}
			animator();
			}
		}

	function floatStart() {
		var now = new Date();
		this.A = this.targetY - this.currentY;
		this.B = Math.PI / ( 1 * this.slideTime );
		this.C = now.getTime();
		if (Math.abs(this.A) > this.findHt) {
			this.D = this.A > 0 ? this.targetY - this.findHt : this.targetY + this.findHt;
			this.A = this.A > 0 ? this.findHt : -this.findHt;
			}
		else {
			this.D = this.currentY;
		   }
		}

	function animator() {
		var now = new Date();
		var newY = this.A * Math.sin( this.B * ( now.getTime() - this.C ) ) + this.D;
		newY = Math.round(newY);
		if (( this.A > 0 && newY > this.currentY ) || ( this.A < 0 && newY < this.currentY )) {
		if ( ie4 )document.all.floatLayer.style.pixelTop = newY;
		if ( ns4 )document.layers["floatLayer"].top = newY;
		if ( ns6 )document.getElementById('floatLayer').style.top = newY + "px";
		   }
		}

	function start() {
		if(ns6||ns4) {
			pageWidth = innerWidth;
			pageHeight = innerHeight;
			layerSetup();
			floatObject();
			}
		else if(ie4) {
			pageWidth = document.body.clientWidth;
			pageHeight = document.body.clientHeight;
			layerSetup();
			floatObject();
		   }
		}
</script>

<div id="floatLayer" style="LEFT: -1000px; WIDTH:300px; POSITION: absolute; TOP: 253px; 200: 128px;">
<a href="#" onclick="closeDiv();">Fechar</a>
Conteudo da propaganda aqui
</div>

Gostaria que a propaganda ficasse na janela por apenas alguns segundos, mesmo que o usuário não clique no botão fechar. Podem ajudar? :blink:

Coloca a linha abaixo depois da chamada do banner:

window.setTimeout(closeDiv,5000);
