Get access to the extension properties from JavaScript

Mon, 26 Jan 2026 18:19:17 GMT

Hello,

Is it possible to get access to the extension properties from JavaScript? In example how to get value of .Chart.Dimension.0.Label property or .Chart.ExtendedProperty.0.Value? Also where I can find list of available .qvpp files?

Thanks.

Can anyone just say Yes/No? Is it supported or not?

There is currently no way to read properties from the javascript code. The only thing you can do is set the property by calling

this.Layout.SetProperty(propertyName, propertyValue);

What do you mean by "available .qvpp files"? Are you talking about built-in qvpp used by standard QlikView objects or about the properties that can be bind to an HTML element in the qvpp file?

Hello,
Thank you for your reply. Yes, I've meant the built-in qvpp files like: .Chart.Expression.0.0.NumberFormat:NumberFormat.qvpp.
Basically what I wanna do is to set a value using the properties page and then from the javascript to obtain this value in order to change how extension behaves or looks like. It is possible at all or I have to use another technique?

As far as i know there is no documentation about built-in qvpp files... I don't think you can do what you want, from what I understand, you can only read evaluation of expressions in the code. Some properties may have consequences on the data (number formatting for example will change the text attribute while keeping the same data attribute), but there is no way to directly read the content of the properties.
