Hi @Jayaprakash R ,

You can use timer to do this kind of stuff.

Hi ,

Use a local variable to store the generated number.
Use a Timer or setInterval in JavaScript to generate a new number every 30 seconds.
Use GetRandomInt(100000, 999999) to produce the number.
Update the UI so the user sees the new number dynamically.
Since this is offline, everything must be client-side only.

You can use the below code in java scriptnode to get random number 

Math.floor(Math.random() * (999999 - 100000 + 1)) + 100000;
