Reading Variable Definition in a Document

Mon, 26 Jan 2026 16:26:21 GMT

Hello,

our goal is to read all the variable defintions in a document. The Problem ist that only 2 variables are displayed in the extension.

If I have selected 3 individual variable definitions to display them, I get an error code 2. In the loop as shown in the sample below it display just 2 rows.

Can anyone help me to get all variable definitions in a exportable format!? It's very important for me and I am not find any solution.

Thanks in advance!

Best Rgds

Thats the sample code:

Qva.AddExtension('Konsolidierung', function(){

var obj = this.Element;

var doc = Qv.GetCurrentDocument();

var varsRetrieved = false;

doc.SetOnUpdateComplete(function(){

if(!varsRetrieved){

Qv.GetDocument("").GetAllVariables(function(variables){

for(var i = 0; i < variables.length; i++){

            var a = variables.name + " = " + variables.value;
            obj.innerHTML=a;

   //var Konsolidierung = this.GetVariable();

//obj.getElementById("ptest").innerHTML = variables.name + " = " + variables.value;
//this.Element.appendChild(p);

//alert(variables.name + " = " + variables.value);

}});

varsRetrieved = true;

}

});

}, false);

Hi Martin,

this is what works for us:

---

(function() {

Qv.AddExtension('ReadVariables', function() {

console.log('ReadVariables eXtension loaded');

var height = this.GetHeight();

var width = this.GetWidth();

var container = $('<div />').css({

height: height,

width: width,

overflow: "auto"

}).appendTo($(this.Element).empty());

Qv.GetCurrentDocument().GetAllVariables(function(vars) {

$.each(vars, function(index, varObj) {

container.append($('<div>' + varObj.name + ' = ' + varObj.value + '</div>'));

});

})();

---

It's worth to mention that the callback function of GetAllVariables( ) runs asynchronous which gives a problem if you assign the values inside to an outer scope variable.
