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

问题描述

 <？xml version =1.0encoding =utf- 8\" >？; 
  xmlns：s =library：//ns.adobe.com/flex/spark 
 xmlns：mx =library：//ns.adobe.com/flex/mx> 
< fx：声明> 
< mx：HTTPService id =httpRSSurl =http://www.petefreitag.com/rss/resultFormat =object/> 
< / fx：声明> 
< s：Panel id =readertitle =Blog Readerwidth =500> 
< mx：DataGrid width =485id =entriesdataProvider ={httpRSS.lastResult.rss.channel.item}click ={body.htmlText = httpRSS.lastResult.rss.channel。项[entries.selectedIndex] .DESCRIPTION}> 
< mx：columns> 
< mx：DataGridColumn dataField =titleheaderText =TITLE/> 
< mx：DataGridColumn dataField =pubDateheaderText =Date/> 
< / mx：columns> 
< / mx：DataGrid> 
< mx：TextArea id =bodyeditable =falsewidth =485x =3y =142height =155/> 
< / s：面板> 
 < / s：Application> 
  

但是当Textarea更改为像下面那样引发Textrea时

 < s：TextArea id =bodyeditable =falsewidth =485x =3y =142height =155/> ; 
  

然后htmlText不支持Spark Textarea。因此产生错误。如何用火花文本区域属性显示HTML格式的文本。 如果您使用 RichEditableText 组件，则可以使用TextConverter类

  var myStr：String =我包含< b> html< / b>标记！ 
 myRichEditableText.textFlow = TextConverter.importToFlow（myStr，TextConverter.TEXT_FIELD_HTML_FORMAT）; 
  

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>

But when Textarea is changed to spark Textrea like below

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

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

解决方案

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);
