用flex动画实现html的marquee功能

<?xml version="1.0" encoding="utf-8"?><s:Application name="Spark_TextInput_textDisplay_horizontalScrollPosition_test"        xmlns:fx="http://ns.adobe.com/mxml/2009"        xmlns:s="library://ns.adobe.com/flex/spark"        xmlns:mx="library://ns.adobe.com/flex/halo">     <fx:Script>        <![CDATA[            protected function init():void {                anim.stop();                pth.valueFrom = 0;                pth.valueTo = txtInput.textDisplay.contentWidth - txtInput.textDisplay.width;                anim.play([txtInput.textDisplay]);            }        ]]>    </fx:Script>     <fx:Declarations>        <s:Animate id="anim"                duration="10000"                repeatBehavior="reverse"                repeatCount="0"                repeatDelay="500">            <s:motionPaths>                <s:SimpleMotionPath id="pth"                        property="horizontalScrollPosition" />            </s:motionPaths>        </s:Animate>    </fx:Declarations>     <s:TextInput id="txtInput"            text="hello javaeye  hello javaeye hello javaeye hello javaeye  hello javaeye hello javaeye hello javaeye"            editable="false"            fontSize="24"            left="100" right="100"            horizontalCenter="0" verticalCenter="0"            creationComplete="init();"            resize="init();"            rollOver="anim.pause();"            rollOut="anim.resume();" />  </s:Application>
