Get variable value

[Anonymous]

Hi,

Does anybody know a good, non deprecated, way in an extension to get the value of a Qlik Sense variable into a Javascript variable  ?

[_jespers_]

Do you mean something like this?

define( [
        "qlik", 
        "text!./template.html"
    ],
    function ( qlik, template ) {
        var app = qlik.currApp(this);

        return {
            template: template,
            support: {
                snapshot: true,
                export: true,
                exportData: false
            },
            paint: function () {
                var qix = this.backendApi.model.enigmaModel.session;
                var numericValue;
                qix.app.getVariableByName('nameOfVariable').then(function(variable){
                    variable.getLayout().then(function(variableLayout) {
                        numericValue = variableLayout.qNum;
                    });
                });
                return qlik.Promise.resolve();
            },
            controller: ['$scope', function ( $scope ) {
            }]
        };

    } );

Hi,

If your extension should be snapshottable, you should make sure the variable value is in the layout, something like this (haven't actually tested this code, so there might be syntax errors):

initialProperties:{
  myVar:{
        qStringExpression: '="vBill"'
  }
}

Or you could use qValueExpression.

You could also use the api's, but then you would have problems with snapshots: it might not work at all, or if it does does you would get the value when the snapshot is shown, not when it was taken.

Hope this helps
