Qv vs Qva

[#1]

Hi,

I'm trying to debug an extension object supplied to us by a 3rd party. I see references to both Qv and Qva (namespaces?) but I'm unable to locate any documentation that explains whether these refer to the same, or different, things.

This document: http://qlikcommunity.s3.amazonaws.com/misc/symbols/Qv.html  refers to Qv as a global object in the QlikView Ajax namespace. It then goes on to provide, among other things, an example of the Qv.AddExtension() method.   This example also includes references to the method Qva.LoadCSS(), which leads me to believe that Qv and Qva refer to different things.  But then the extension object I'm working with includes an invocation of Qva.AddExtension().. hence the confusion on my part.

Any clarification would be very appreciated.

Thanks

Steve

Hi Steve,

I'm currently at the very same point. What we are talking about is the QlikView JavaScript API.

Because of that I had a look into the JavaScript API References for the version 10 and 11.

JavaScript API Reference 10 http://community.qlik.com/docs/DOC-2605

JavaScript API Reference 11 http://community.qlik.com/docs/DOC-2673

If you compare them you will see, that in version 10 the "Qva" is used everywhere as reference. In opposite to that version 11 exclusively uses the "Qv". From this single fact I cannot guarantee that the difference is the API version, but it seems to be. So for me mixing "Qva" and "Qv" would mean to mix functions of the different APIs.

Thanks Eric,

That would explain why some of the documentation refers to the same "functions" by both Namespaces. I would assume that there is some level of backwards compatibility between the versions, but then again, we're talking about QlikView.

Steve
