Getting started with text input and dynamic text fields with ActionScript 2.0 or 3.0

Question

I know this is a simple question, but I haven't worked much with ActionScript...

I know how to create a text input field with Flash. I can create it on the stage and give it an instance name.

What is the code to capture the value of a text input field and display that value in a dynamic text field? How does this process differ between ActionScript 2.0 and 3.0?

Answer 1

It really depends when you want to update the dynamic textfield, with the input textfield's data.

If you want to update the dynamic text field once then try this:

//AS3
myDynamicTF.text = myInputFT.text;

//AS2
myDynamicTF._text = myInputFT._text;

If you want to update the dynamic textfield every time the user types in the input field, then in AS3 you need to listen for the TextField's Change event

//AS3
myInputFT.addEventListener(Event.CHANGE, changeHandler);

private function changeHandler(e:Event):void 
{
    myDynamicTF.text = myInputFT.text;
}

For AS2 you can just set the inputfield onChange method:

//AS2
myInputFT.onChanged = function(textfield_txt:TextField) 
{
    myDynamicTF._text = textfield_txt._text;
};
