I've tried to access buttons in my menu. I only want to add listeners to the items that is in the XML file im loading.
The thing is, i dont know how to call a button i've named "Var1_btn" when i've got a string "Var1".
Does anyone know how to call buttons from a for-loop?
for each(var chapter in presentation_xml.*)
{
chapter + "_btn".addEventListener(MouseEvent.MOUSE_DOWN, traceit);
}
is what i came up with...
Assuming you load the xml into a variable called presentationXML, it's like this:
for each(var chapter in presentationXML.*)
{
this[chapter + "_btn"].addEventListener(MouseEvent.MOUSE_DOWN, traceit);
}
You can use:
for each(var chapter in presentation_xml.*)
{
this[chapter + "_btn"].addEventListener(MouseEvent.MOUSE_DOWN, traceit);
}
but you could also use getChildByName, like this:
for each(var chapter in presentation_xml.*)
{
var myBtn:MovieClip = getChildByName(chapter + "_btn");
myBtn.addEventListener(MouseEvent.MOUSE_DOWN, traceit);
}
Here is a good post on when to use getChildByName.
DisplayObjectContainer::getChildByName()
Better use chapter.toString().
The same effect, but other coder will read it ad understand, that chapter is being converted from XML to its string representation when concatenates with string literal.
