I am trying to figure out whether it is possible in Javascript to implement an eventListener into a while loop which can pass a value to a variable inside the loop. I need this to cancel an infinite loop which continiously should send a data frame to a TCP-socket (watchdog). When the socket is closed the loop should end. I use a webworker for this purpose, but it does not work.
Here is the code:
// WebWorker with infinite loop
var check = "true";
let i = 0;
let j = 0;
var returnedEvent;
while (check) {
self.postMessage(i);
onmessage = (event) => {
returnedEvent = event.data;
console.log("worker: " + event.data);
let check = returnedEvent;
}
sleep(100);
}
console.log("loop completed");
function sleep(delay) {
var start = new Date().getTime();
while (new Date().getTime() < start + delay);
}
