我正在尝试使用字符串更新多个<mx:text>对象。htmlText我遇到的问题是只有最后一个<mx:text>对象在数据更改时变得可见。

我错过了<mx:text>标签上的一些基本内容吗？

使用弹性 4.6

谢谢艺术

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>

我看不出你的标签有什么问题。尝试在为每个侦听器指定的字段中打印出 meta.hasOwnProperty 值，这样您就可以查看结果是否确实是您认为的那样。
