在 Spark TextArea 中显示 HTML 文本 [英] Display HTML text in the Spark TextArea

问题描述

下面的代码运行良好...

The Below code is running well...

<?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" >
 <fx:Declarations>
  <mx:HTTPService id="httpRSS" url="http://www.petefreitag.com/rss/" resultFormat="object" />
 </fx:Declarations>
  <s:Panel id="reader" title="Blog Reader" width="500">
  <mx:DataGrid width="485" id="entries" dataProvider="{httpRSS.lastResult.rss.channel.item}" click="{body.htmlText=httpRSS.lastResult.rss.channel.item[entries.selectedIndex].description}">
   <mx:columns>
    <mx:DataGridColumn dataField="title" headerText="TITLE"/>
    <mx:DataGridColumn dataField="pubDate" headerText="Date"/>    
   </mx:columns>
  </mx:DataGrid>
  <mx:TextArea id="body" editable="false" width="485" x="3" y="142" height="155"/>
 </s:Panel>
 <s:Button label="Load" x="10" y="329" click="{httpRSS.send()}"/>
 </s:Application>

但是当Textarea改变为像下面这样触发Textrea时

But when Textarea is changed to spark Textrea like below

<s:TextArea id="body" editable="false" width="485" x="3" y="142" height="155"/>

那么 htmlText 不支持 Spark Textarea.因此产生错误.如何使用 spark 文本区域属性显示 HTML 格式的文本.

Then htmlText doesn't support Spark Textarea. Hence produces error. How does one go about displaying HTML formatted text with spark Text Area Property.

推荐答案

如果您使用的是 RichEditableText 组件，您可以使用 TextConverter 类来这样做

If you're using the RichEditableText component instead, you can do it this way using the TextConverter class

var myStr:String = "I contain <b>html</b> tags!";           
myRichEditableText.textFlow = TextConverter.importToFlow(myStr, TextConverter.TEXT_FIELD_HTML_FORMAT);
