關於Flex4，textArea控件的htmlText屬性問題

textArea控件有個textFlow屬性 就是這樣咯,下面就寫代碼了：

<s:TextArea id="txt" x="185" y="122" textFlow="{TextConverter.importToFlow(str, TextConverter.TEXT_FIELD_HTML_FORMAT)}">
   </s:TextArea>

如果你寫在‍<fx:Script>就這樣寫吧：

txt.textFlow=TextConverter.importToFlow(str, TextConverter.TEXT_FIELD_HTML_FORMAT)

這里的txt是textArea控件的實例名稱，str就是一個關於htmlText的字符了；

好了下面就給個完整的代碼：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" creationComplete="init()">
<s:TextArea id="txt" x="157" y="118" />
<s:Button id="btn" x="360" y="334" label="發送"/>
<s:TextInput id="input" x="167" y="332"/>
<fx:Script>
