Hi, I have created one flash as3 (main.fla) file with next, previous buttons and I have loaded one child swf (firstchild.swf) file into main file. In child swf also I have loaded another child swf (grandchild.swf) [grand child to main file]. I have disabled the next button in main.fla file and trying to enable the button from grandchild.

My coding look like:

main.fla:

next_btn.mouseEnabled = false;.

grandchild.fla:

I have tried two scirpts:

  1. MovieClip(root).next_btn.mouseEnabled = true;
  2. (root as MovieClip).next_btn.mouseEnabled = true;

but any one of them doesn't works for me. can any one help me to solve my problems.

Thanks in advance........

Note:  Output says...

TypeError: Error #1010: A term is undefined and has no properties.

If that is line 1 of the grandchild's code then it appears you do not need to have it in the grandchild and could have it execute in the child instead when it loads the grandchild.

A proper way of having a child talk to a parent is to just have the child dispatch an event for which the parent (main file) assigns a listener when that child is first loaded.  Example:

Add something to trigger the event in the child:


dispatchEvent(new Event("eventTriggered"));


In your loading/parent swf, listen for the complete event on the Loader.contentLoaderInfo.  In the complete event handler, add a listener for the event on the loaded swf.


// event handler triggered when external swf is loaded
function loaderCompleteHandler(event:Event) {
    MovieClip(event.currentTarget.content).addEventListener("eventTriggered", eventHandler);
}

function eventHandler(event:Event):void {
    trace("event dispatched in loaded swf");
}

    Hi Ned,

    Thanks for your information. But what my problem is firstchild.swf was published through captivate and it is a quiz. After submitting the quiz only I need to enable the next button. For that purpose I have loaded one flash swf file (grandchild.swf) into captivate. I have written one trace function on grandchild.swf time line and its working fine but I am unable to access the next button of main file or any other functions.

    If there is any other methods for communicating with captivate quiz submit button, please tell me. Because I am learner, please help me to rectify this problem.

    Thanks again for giving response for my question.

    Have you tried tracing the MovieClip(root) reference to see what it comes up as?  I am guessing that when the file loads it has not yet been able to define a root before that line of code tries to execute.  You might need to use an ADDED_TO_STAGE event listener and wait until that event occurs before you try to target the root.
