Calling a Webservice from within a javascript object - closure issue?

Hi,

I'm making a client side call to a web services but I need to wrap up the functionality that makes the call within another object. The code is below. The code worked fine before I wrapped it in the "ImageViewer" object but now when I try to call the Web Service Method it doesn't recognise the onComplete call back function and says "onComplete" undefined. (See the getImageIDs method). I suspect this is something to do with scope and/or closure but I've been unable to come up with a solution. What is the correct way to do this? Any help will be appreciated.

Type.registerNamespace(

"Raydius");

Raydius.ImageViewer =

function(ImageDivID, ImageListDivID){this.ImageDiv = $get(ImageDivID);this.ImageListDiv = $get(ImageListDivID);this.ImageIDs = [];this.Images = [];

}

Raydius.ImageViewer.prototype = {

getImageIDs:function(id){

// Call the WebService

RaydiusWS(id, onComplete);

},

onComplete:

function(results){

alert(results);

},

onTimeOut:

function(results){

alert(

"Timeout");

},

onError:

function(results){

alert(

"Error");

}

}

Raydius.ImageViewer.registerClass(

'Raydius.ImageViewer');function initImageViewer(){

var viewer =new Raydius.ImageViewer("ImageDiv","ImageListDiv");

viewer.getImageIDs(1);

}

See if my example here helps you:

Thanks for the response. There was actually a daft error in my code that was stoppinmg it working both the other post you directed me to was helpful. The userContext param is very useful.

Thanks
