Get a Javascript variable outside the script

[Akayy]

If your variable is not in the root of your page, then you have to use this method suggested by patrick

Using App Connect with JavaScript Functions

Not sure why it wouldn’t work with the initial value. If you want to only update a property of the existing object then try: // get reference to variable component var myVariable = document.getElementById(var_order).dmxComponent; // get order object from component var order = myVariable.get("value"); // update order order.currentPrice = newPrice; // set variable value with updated order object myVariable.set("value", order);

Try typing dmx.app.data.vuFp.value in your browser console, if it comes with undefined, then probably it's nested in your page..
