Referencing a qlikview object within an extension

Anonymous — Mon, 26 Jan 2026 16:26:21 GMT

Hi All,

I am writing an extension that renders a google vizualization. On the same sheet as my extension, I have two listboxes that display data fields as normal.

From within my javascript I would like to be able to obtain a handle to these listboxes so that I can iterate over their data.

The API documentation says to use: 'Qv.GetCurrentDocument().GetObject(objectName)' where objectName is defined as 'The name of the object you want to append your callbackFn to.'

However, the problem I'm having is that I do not know the name of my objects in order to be able to reference them. I have tried the obvious things like using their objectId etc. but none of these are successful. No matter what I use for the objectName parameter, I don't get back a proper handle to the object:

Example 1

var mydoc = Qv.GetCurrentDocument();

var ch = mydoc.GetObject("LB02");

alert(ch.Layout.ObjectId);

Example 2

var mydoc = Qv.GetCurrentDocument();

var ch = mydoc.GetObject("Document\LB02");

alert(ch.Layout.ObjectId);

After running either of the above code samples, I expect to obtain an alert with the ObjectId of my listbox in order to prove I have obtained a correct handle. However, the alert box is always just blank.

Can anybody please advise on how I can find the internal QV name assigned to each object? Or perhaps an alternative way to get a hold of my listboxes from within my javascript?

Thanks,

Padraic

Hi Padraic, the GetObject-Function is asynchronous. You need to await the callback of this function with `SetOnUpdateComplete()`. https://help.qlik.com/en-US/qlikview-developer/12.1/apis/js+API/symbols/Qv.Document.html#SetOnUpdateComplete You could try something like this: var mydoc = Qv.GetCurrentDocument(); var ch = mydoc.GetObject("LB02"); ch.SetOnUpdateComplete(()=>{ alert(ch.Layout.ObjectId); });

I did, but get multiple submissions of the callback. How do I avoid that?
