problem with as3 linking with xml

Report · Jul 15, 2011

Hi

Please Please help me with this.

I am getting

"Error #1069: Property data not found on flash.display.Sprite and there is no default value.

at flashhaupt01_fla::GalleryData01_1/imagepress()" error in as3.

I am trying to get the url from xml into as3, but not getting how to do it. please help me.

I need to demo this within 1 hour

here is my code

var xmlReq:URLRequest = new URLRequest("XML/ImagesData01.xml"); // rename to your file!!!

var xmlLoader:URLLoader = new URLLoader();

//xmlLoader.addEventListener(Event.COMPLETE, xmlLoader); // event listener b4 load!!!

xmlLoader.load(xmlReq);

var myXML:XML;

var headLoader:Loader;

function imagepress(e:MouseEvent):void {

//navigateToURL(new URLRequest("XML/ImagesData01.xml"));

myXML = new XML(e.target.data);

for (var i:int = 0; i < myXML.children().length(); i++)

{

headLoader = new Loader();

headLoader.load(new URLRequest(String(myXML.data.@image)));

// headLoader.x = startX;

//headLoader.y = 0;

headLoader.name = String(i);

addChild(headLoader);

}

please help me

Assuming imagepress is called when you click on some image, the target of the event (e) could be any object within the object that has the event listener assigned to it. There error seems to be indicating that you are expecting to extract a "data" property from a Sprite object that has been clicked.

Where is the data you seek?

Thanks for replying,

I have some chores I need to get done, so here's what I'll leave you with. It appears you are assigning the CLICK event listener to a Sprite object declared as planeMC. What I sugest is that you declare it as a MovieClip instead so that you can dynamically assign it a reference number ( i ) as a property, let's say you name it "num". That way, later on in your imagepress function you can use e.currentTarget.num to identify which url from the urllink array you need to use.... here's a couple snips...

var planeMC:MovieClip = plane.container; // your current line

planeMC.num = i;

function imagepress(e:MouseEvent):void { // your code from earlier

navigateToURL(new URLRequest(urllink[e.currentTarget.num]));

I have no familiarity with whatever the Plane object is, but whatever it contains that is called 'container' is apparently a Sprite, so if you have no ability to change that, then you'll need to find another way to get the value of i to associate with the planeMC object.

So if you're stuck with the Sprite, then what you might try is to use its name to carry the value. I just don't know that there is any valididty in naming an object with a number... I know it won't work if you hard code it that way. So maybe you name the Sprite something like "pmc_"+String(i), and then later on in your iamgepress function you extract the value of i from the name using String.split("_") to isolate the number as the second element of the array that is returned.
