We are building a bookstore and have one bug we can't figure out. Some of the items' thumbnail images are missing. We wrote some code that tries to load the image, and if it doesn't load correctly it replaces it with a default image. The problem is, the function is returning the string before the image loads or fails and therefore isn't returning the right data.
Any suggestions?
I'll paste our current code below:
The image tag:
<mx:Image id="img" height="160" source="{sendImage(of.currentItem.prod.getItemAt(O).image)}" ioError="strUse='assets/pic/defaultITM.jpg'"/>
The function:
private function sendImage(str:String):String
{
var path:String = "assets/pic/";
var strUse:String = str;
// Looks to see if the image exists
var ldr:URLLoader = new URLLoader();
ldr.addEventListener(IOErrorEvent.IO_ERROR, imgFailed);
ldr.addEventListener(Event.COMPLETE, imgCompleted)
function imgFailed (e:IOErrorEvent):void {
strUse = "defaultITM.jpg";
}
function imgCompleted (e:Event):void{
strUse = str;
}
var url:String = "http://dev.ourserver.org/assets/pic/" + str;
var urlReq:URLRequest = new URLRequest(url);
ldr.load(urlReq);
return path + strUse;
}
