How do I use UUID?

Question

I use PhoneGap in Devextreme. I try Get UUID. But it isn't working and get an error. How do I use it? Why do I get an error?

error

"onDeviceReady isn't defined"

Add following to config.xml:

<plugin name="cordova-plugin-uniquedeviceid" source="npm" />

Add following to index.js:

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
try {
 var uuid = device.uuid;
    alert(uuid);
 } catch (e) {
  alert(e);
        }
}

I saw that you are using cordova-plugin-uniquedeviceid package to get uuid.
This is how cordova-plugin-uniquedeviceid library documentation tells to get device uuid.

// Get UUID
function onDeviceReady() {
  window.plugins.uniqueDeviceID.get(success, fail);
}


function success(uuid){
    console.log(uuid);
};

document.addEventListener("deviceready", onDeviceReady, false);
