让title动起来

function newTitle() {   
	var titleDOM = document.getElementsByTagName("title")[0];
	var text = titleDOM.innerHTML;
	var cacheTitle = titleDOM.getAttribute("cacheTitle");
	if(!cacheTitle){
		cacheTitle=text;
		document.getElementsByTagName("title")[0].setAttribute("cacheTitle",text);
	}
	var nLen = cacheTitle.length;
	var sEndChar = cacheTitle.substring(nLen-1,nLen);
	var nNowIndex = text.indexOf(sEndChar)+1;
	text = text.substring(1,nNowIndex);
	//log("text = "+text+",sEndChar = "+sEndChar+",nNowIndex ="+nNowIndex);
	if(nNowIndex<=0 ||!!text==false){
		document.title = cacheTitle;
	}else{
		document.title = text;
	}
//		document.title=text.substring(1,text.length)+text.substring(0,1); 
	setTimeout("newTitle()", 500);
}
