[Flashcoders] Testing before removing a child

2009-11-18 Thread Alan Neilsen 
I am using loader_clip.removeChild(ldr); to remove child objects from my loader 
clip, and I want to test if a child object is there before removing it. I 
thought it would be something like
if (loader_clip.child !=0) {   // or !=, or !=null, or ==true, or 
something like that
loader_clip.removeChild(ldr);
}

But when I trace (loader_clip.child) it comes back undefined whether the 
child is still there or not.

What can I use to test this so loader_clip.removeChild(ldr); doesn't produce an 
error if the child has already been removed?

If I understand properly what you mean, the contains method is what you're
looking for.

if (loader_clip.contains(ldr)){
loader_clip.removeChild(ldr);
}
