Named functions with return values

[Sebarry]

Hi,

I would like to change the following anonymous to a named function which receives the newsID as an argument and returns the title, content and image of the article (which are currently done within the function).

titleMC.onRelease = function()
{
    varSenderContent = new LoadVars();
    varReceiverContent = new LoadVars();
    varSenderContent.newsID = this.newsID;
    varSenderContent.sendAndLoad("localhost/GetNewsDetail.php", 
         varReceiverContent, "GET");
    varReceiverContent.onLoad = function() 
    {
         for (p in this) 
         {
              if (typeof this[p] == "string") 
              {
	 articleContent = this.data.split('~');
	 _root.copy_mc.article.text = articleContent[1];
	 image = "http://www.bemod.co.uk/images/newsImages/" + 
                       articleContent[2];
								var CTNR_WIDTH=525; //original width of container			var CTNR_HEIGHT=156; //original height of container
								loadMovie(image, "_root.photo_mc"); 
								_root.photo_mc._xscale=CTNR_WIDTH/800*100;							_root.photo_mc._yscale=CTNR_HEIGHT/600*100;
								_root.title_mc.title.text = articleContent[0];
            }
        }
    }
}

For calling the function I think I use the following syntax, once it's been given a name,

titleMC.onRelease = returnArticleContent( newsID )

but how do I retrieve the values that I returned from the function?

Thanks,

Sean

Hi, you cannot make a function return multiple values, what you can do is make the function do all by itself without returning anything, or returnan array or an object and use that returned array/object to do whatever you whant.
Anyway, you cannot call a function that return values the way you did, that way the button will recieve the returned "something" . You need to call the function from a variable, so the variable will be the one recieving what the function returns. Like this:
[CODE=actionscri pt]
titleMC.onRelea se = function() {
//if the function returns an array:
var some:Array = returnArticleCo ntent; //yes, if you dont pass parameters, you don't put ();
//if the function returns an object:
var some:Object = returnArticleCo ntent;

//now do whatever you want with the "some" variable.
}
[/CODE]
If the function returns an object, the variable will become that object. And then you can work with that variable -now an object- and do whatever you want width it.
