Design a recurring report using an endless JavaScript cycle

Question

Design a recurring report using an endless JavaScript cycle

I am in the process of creating a brand new scheduled report and have encountered an issue. How can I incorporate a script that includes a loop to run a specific function every 10 seconds? Here's what I have so far:


var count = 1;
while(count > 0){
    setTimeout(function(){myFunction()},10000);
    count--;
}

Oddly enough, when I test this script within the report studio (without scheduling it), it works perfectly fine. However, once the report is scheduled, the script ceases to work. Can anyone shed light on why this might be happening or perhaps offer an alternative solution?

Appreciate any help in advance.

To maintain the existing structure, one can implement a slightly recursive approach using setTimeout:

var recurringTask = function(){
  // Perform a task
  setTimeout(recurringTask, 10 * 1000);
};

However, a more efficient method is to utilize setInterval:

setInterval(function(){
  // Perform a task
}, 10 * 1000);

If there is a need to terminate the interval, it is advisable to preserve the reference:

var recurringTask = setInterval(function(){
  // Perform a task
}, 10 * 1000);

// .. Circumstances arose necessitating cancellation
clearTimeout(recurringTask);

Opt for setInterval in place of setTimeout.

Furthermore, the while loop you have is unnecessary.

Simplify it by using: setInterval(myFunction, 10000);
