Question

我正在尝试使用<mx:text>字符串更新多个htmlText个对象。我遇到的问题是，当数据发生变化时，只有最后一个<mx:text>对象变得可见。

我是否遗漏了<mx:text>代码中的基本内容？

使用flex 4.6

test1.html

<rtnA><![CDATA[ <font color="#0000ff" face="helvetica" size="15" >This is rtnA</font> ]]></rtnA>  
<rtnB>this is rtnB</rtnB>
<rtnC>this is rtnC</rtnC>
<rtnD><![CDATA[ <font color="#aa00aa" face="Arial" size="15" >This is </font><font color="#0000ff" face="helvetica" size="15" >rtnD</font> ]]></rtnD>

我认为您的代码没有任何问题。尝试在为每个侦听器指定的字段中打印出meta.hasOwnProperty值，以便您可以查看结果是否确实是您认为的结果。

flex 4.6使用CDATA解析htmlText对象，仅显示最后一个对象
