			function enterFrameListener(event:Event) {
				myText.setTextFormat(myTextFormat_old);
				var charIndex:int = myText.getCharIndexAtPoint(myText.mouseX,myText.mouseY);//不断取得指定位置的字符索引
				if(charIndex==-1){//如果鼠标移出文本
					return;}
				myText.setTextFormat(myTextFormat_new,charIndex,charIndex+1);
			}
			
			addEventListener(Event.ENTER_FRAME, enterFrameListener);//注册桢循环事件
			addChild(myText)

这都行。。。我觉得直接用<a/> + css更方便点吧。
