Using Expression in Definition.xml/Properties.qvpp/Script.js

Mon, 26 Jan 2026 16:26:21 GMT

Hey,

I want to have access via JavaScript to an expression which I have defined in the Definition.xml.

Definition.xml:

===========

<?xml version="1.0" encoding="utf-8"?>

</ExtensionObject>

Properties.qvpp:

============

<a href="#">EXTENSIONNAME</a>

</h3>

</div>

<a href="#">Presentation</a>

</h3>

<a href="#">Caption</a>

</h3>

<a href="#">Options</a>

</h3>

</div>

</div>

Script.js

======

var user = this.Layout.Text0.text;

What make I wrong, in the ObjectProperties window, there stands no text, also I haven' t this attribute in my JavaScript(this.Layout.(Text0 not there))

Hey,

Look at the attached sample and it should give you an hint.

Unless you are building something for QV10 or you really really need a custom properties panel I would recommend that you make use of the automatic generation of properties that was introduced with QV11.

If you add a few more properties into your definition.xml, mainly a type property for your text tag, QlikView will generate a nice looking properties page for you.

Hello Alexander,

thanks for your useful answer, I have test your file and this is working. Now I have use your "code" and copied to my project, but this is not working.

Definition.xml:

<?xml version="1.0" encoding="utf-8"?>

</ExtensionObject>

Script.js:

function MyExtension_Done() {

Qv.AddExtension("MyExtension",

function() {

var extensionName = "MyExtension";

var extensionPath = Qva.Remote + "?public=only&name=Extensions/" + extensionName + "/";

var _this = this;

var osuser = _this.Layout.Text0.text;

....

What is there the problem, I don't understand this.

Are you running QV11 SR1 by any chance?

The code looks ok to me.

When there is a change in the Definition.xml file, you need to remove all extension objects of that type in the QV file and add them again. Have you tried that?
