Getting started
You must first connect to the Qlik Sense app, and you do this with the qlik.openApp method. You can then use the qlik.app.variable.get method to get an existing variable.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//get an existing variable
app.variable.get('yTgsRI').then(function(model){
myvar = model;
});
});Examples of use
Learn what you can do with the Variable API.
Create a new variable
Use the qlik.app.variable.create method to create a new variable.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//create a new variable
app.variable.create({
qName : 'myvar',
qDefinition : 'Month'
});
});Create a session variable
You can also create a variable that only exists in the session. To do so, use the qlik.app.variable.createSessionVariable method.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//create a new session variable
app.variable.createSessionVariable({
qName : 'myvar',
qDefinition : 'Month'
});
});Get the variable content
Use the qlik.app.variable.getContent method to get the variable content.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//get the variable content
app.variable.getContent('MYVAR',function ( reply ){
alert( JSON.stringify( reply ) );
});
});Set a numeric value
Use the qlik.app.variable.setNumValue method to set a numeric variable value.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//set numeric value
app.variable.setNumValue('MYVAR',5);
});Set a string value
Use the qlik.app.variable.setStringValue method to assign a string value.
var config = {
host: 'QSE_domain',
prefix: '/',
port: 443,
isSecure: true
};
require(["js/qlik"], function(qlik) {
//open the app
var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config);
//set string value
app.variable.setStringValue('MYVAR','=(1+1)');
});
