Accessing Items in an Array - AS3 - arrays

Question

I've got an Object item.movieimage that contain some texts (item:Object) that is retrieve from my database. The text is changing every week automatically.
If I do trace(item.movieimage) the output is something like this :
text1
text2
text3
text4
The words changes as the code is taking them from my database. The database changes the words every week.
Now, I want my AS3 code to display the third element of item.movieimage.
I've tried to do this :
var my_str:String = item.movieimage+",";
var ary:Array = my_str.split(",");
trace(ary[2]);
But it's not working. The output is "undefined".
Do you know how can I access a specific item in the Array that I've created ? Or how can I access the third item of item.movieimage ?
If I do trace(ary);, the output is :
text1,
text2,
text3,
text4,
EDIT :
For infos :
trace(typeof(item.movieimage)) and trace(typeof(ary)) are :
typeof(item.movieimage)=string
typeof(ary)=object
EDIT 2 :
Here's a screen capture of item.movieimage
Screen Cap of item.movieimage
EDIT 3
Here's my code in order to understand how "item.movieimage"is working
//Variables for downloading content from my database to my AS3 code
var urlReqSearchAll: URLRequest = new URLRequest("http://www.myWebSite/searchMovie4.php");
var loader5:URLLoader = new URLLoader();
//downloading content
function searchAll():void {
if (contains(list)){
list.removeChildren();
}
urlReqSearchAll.method = URLRequestMethod.POST;
loader5.load(urlReqSearchAll);
loader5.addEventListener(Event.COMPLETE,complete);
var variables:URLVariables = new URLVariables();
}
//Content Downloaded.
function complete(e:Event):void {
addChild(list);
products = JSON.parse(loader5.data) as Array;
hourSaved.data.saved=loader5.data;
products.reverse();
for(var i:int = 0; i < products.length; i++){
createListItem(i, products[i]);
}
displayPage(0);
showList();
}
// If too much items --> creates multiple page
const itemsPerPage:uint = 7;
var currentPageIndex:int = 0;
function displayPage(pageIndex:int):void {
list.removeChildren();
currentPageIndex = pageIndex;
var firstItemIndex:int = pageIndex * itemsPerPage;
var j:int = 0;
var lastItemIndex: int = firstItemIndex + 7; // as lastItemIndex should be 10 more
if (lastItemIndex > products.length) // if lastindex is greater than products length
lastItemIndex = products.length;
for(var i:int = firstItemIndex; i< lastItemIndex; i++){
createListItem( j, products[i]); // j control the position and i points to particular element of array..
j++;
}
next.visible = lastItemIndex < products.length - 1;
if(currentPageIndex==0){
previous.visible=false;
}
}
// Display the information downloded from my database
function createListItem(index:int, item:Object):void {
var listItem:TextField = new TextField();
var myFormat:TextFormat = new TextFormat();
myFormat.size = item.title.length > 13 ? 22 : 26
listItem.multiline = true;
listItem.wordWrap = true;
myFormat.align = TextFormatAlign.CENTER;
myFormat.color = 0xA2947C;
myFormat.font = "Ebrima";
myFormat.bold = true;
listItem.defaultTextFormat = myFormat;
listItem.x = 135;
listItem.y = 123+ index * 84;
listItem.width = 200;
listItem.height = 80;
listItem.addEventListener(MouseEvent.CLICK, function(e:MouseEvent):void {
showDetails(item);
});
list.addChild(listItem);
str = item.title;
}
My php file "SearchMovie4.php" is like this :
$products = array();
while ($row = mysql_fetch_array($sql_result)) {
$products[] = array(
"title" => $row["theTitle"],
"movieimage" => $row["movieimage"],
"movielength" => $row["movielength"],
"story" => $row["story"],
);
}
echo json_encode($products);
So, if I do trace(item.movieimage) in AS3 code, it will display all the items in the row movieimage of my database.
If I do trace(item.title) in AS3 code, it will display all the items in the row title of my database.
What I'd like is to be able to do, in my AS3 code, trace(item.movieimage[2]) in order to show me the third item in the row "movieimage".

Answer 1

Well, the text you've provided to the movieimage property of the item object has not the same delimiter as what you have provided to the split() method; in your case the character of comma!
I suspect the delimiter you have, is the "space" character or a new-line character, like the character of carriage retrun.
In the following code snippet, I've used the "space" as the delimiter character:
var item:Object = new Object();
item.movieimage = "text1 text2 text3 text4";
var my_str:String = item.movieimage;
var ary:Array = my_str.split(" ");
trace(ary[2]); // text3

Answer 2

As #someOne said the output shows the list items are each on a new line, so you need to split() against newlines. One of these should work:
// if server uses "\n" newline char
var movies:Array = item.movieimage.split("\n");
// if server uses "\r" carriage return char
var movies:Array = item.movieimage.split("\r");
// if you aren't sure or there's a mixture of newline chars
var movies:Array = item.movieimage.split(/[\r|\n]+/);
Also note that if you have any control over how the server returns these values, you should just return a JSON array (since I see in your screenshot you are already decoding JSON), then you won't have to do any string splitting.
