   Hi…

   I am really new to Flex, I mean I am just 2 weeks doing Flex. I had encountered some difficulties…

   I had a button and the click event will call a function that returns a value of type string.

   Below is the code;
   click=”editState()”

   This event cannot be raised as this function requires a string value to pass and executes the function.

   Below is the function code;
   private function editState(passedValue:String):void {
   //code goes here
   }

   Now, what I want to do is to capture a label.text value and put it in the call function under click event but how am I supposed to do that? I tried putting like editState(’label.text’). Sorry, I am very new… Please advice

     Data Binding? try addin editState({label.text})

   Could add a transition to this too.

   John – What you want to do is:

   click=”editState(Button(event.currentTarget).label)”

   Typically though, you would pass the event as the parameter and then access the currentTarget from your handler:

   private function editState(event:Event):void {
   var passedValue:String = Button(event.currentTarget).label;
   //code goes here
   }

       @John,

       What about something like this:

       <?xml version="1.0" encoding="utf-8"?>
       <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
        
           <mx:Script>
               <![CDATA[
                   import mx.controls.Alert;
        
                   private function editState(passedValue:String):void {
                       Alert.show("You entered: " + passedValue);
                   }
               ]]>
           </mx:Script>
        
           <mx:TextInput id="lbl" />
        
           <mx:Button id="myBtn"
                      label="mx:Button"
                      click="editState(lbl.text);" />
        
       </mx:Application>

   Hi Peter,

   Thanks for your respond. Yes I know that code works but somehow when I do that, it appears that the page do not recognize the label and resulting an error of “1120: Access of undefined property lblTry.”. Any ideas of why it is happening? I tried pasting my code here but somehow the page thought my comments are spams.

   Hope you can help..

     @John,

     I couldn’t really say without seeing the code.
