Answer 1

用flex可以实现<mx:application xmlns:mx="http://www.adobe.com/2006/mxml">
layout="vertical"
verticalAlign="middle"
backgroundColor="white"&gt;</mx:application>
 
<mx:script>
<!--[CDATA[
private function textArea_textInput(evt:TextEvent):void {
if (evt.text == "\n") {
evt.preventDefault();
}
}
]]-->
</mx:script>
 
<mx:textarea id="textArea">
verticalScrollPolicy="on"
width="160"
height="120"
textInput="textArea_textInput(event);"&gt;
<mx:text>The quick brown fox jumped over the lazy dog.</mx:text>
</mx:textarea>
