Define interval timer  and execute script every defined milliseconds

 

let InternalNumber=window.setInterval(function,timer in milliseconds)

 

Note: The system execute the event system only every 1 second. If you define 500, the system execute this every 1 second and not 500 ms.

 

you can clear this timer with

window.clearInterval(internalNumber);

 

Example:

Show clock in status bar

window.setInterval(()=>statusBar.setText("ok","Current Time Date "+Date());,1000);

 

Alternative

// Define function in long way
window.setInterval(function(){statusBar.setText("ok","Current Time Date "+Date())},1000);
 
// execute external function
function displayTimer(){
statusBar.setText("ok","Current Time Date "+Date())
}
window.setInterval("displayTimer()",1000);
