Question

I’m working with a Flex 4 mxml file that uses a textFlow for RichEditableText as follows:

<s:RichEditableText>
    <s:textFlow>
        <s:TextFlow>
            <s:p>Here is your result: {myVariable}</s:p>
        </s:TextFlow>
    </s:textFlow>
</s:RichEditableText>

myVariable is returned from the middleTier, and equals character “a”, “b”, or “c”. But since I need to display a message depending on what the character is, I want to call an actionscript function to decode myVariable. For example:

private function myFunction(myVariable):String {
  if (myVariable=="a") 
      myMsg = "You selected letter a";
  else if (myVariable=="b")
      myMsg = "You selected letter b";
  else
      myMsg = "You selected letter c";
  return myMsg;
}

I’m not sure how to do this, but I tried the following:

<s:RichEditableText>
    <s:textFlow>
        <s:TextFlow>
             <s:p>Here is your result: {myFunction(myVariable)}</s:p>
        </s:TextFlow>
    </s:textFlow>
</s:RichEditableText>

Although it compiled fine and ran, the result was — nothing got displayed, not even the Here is your result: text.

Any idea how to achieve this? Alternatively, if it’s not possible to call an actionscript function from inside the <s:p> ... </s:p>, then can this be achieved using an inline (sometimes called shorthand) if/then/else actionscript statement?

Thanks for any comments.

You can add text dynamically.refer this link http://blog.flexexamples.com/2009/10/09/dynamically-adding-paragraphs-to-a-spark-richtext-control-in-flex-4/
