Question

Using setTimeout() in JavaScript to create a delay between functions

Is there a way to add a delay between the execution of each function in my program? Currently, I have the following setup:

function function0() {
    setTimeout(function1, 3000);
    setTimeout(function2, 3000);
    setTimeout(function0, 3000);
}

While there is a delay between each execution of function0, there seems to be no delay between function1 and function2. How can I address this issue?

Answer №1

This solution may not be the most graceful, but it should get the job done. In this process, function 1 will be triggered around 3 seconds after function 2 finishes execution, and the same delay applies between function 1 and the loop function.

function function0() {
    setTimeout(function() {
        // <my_function2>

        setTimeout(function() {
            // <my_function1>

            setTimeout(function0, 3000);
        }, 3000);
    }, 3000);
}

    }, 3000);

Every action is carried out with a 3-second delay. Is this intentional?

function delayedFunctions() {
    setTimeout(firstFunction, 3000);
    setTimeout(secondFunction, 6000);
    setTimeout(delayedFunctions, 9000);
}

Alternatively, you have the option to execute the following code:

function doFunction0() {
    setTimeout(doFunction1, 3000);
}
function doFunction1() {
    /*
     Insert your code here
     */
    setTimeout(doFunction2, 3000);
}
function doFunction2() {
    /*
     Insert your code here
     */
    setTimeout(doFunction3, 3000);
}
function doFunction3() {
    /*
     Insert your code here
     */
}

setTimeout is designed to be non-blocking, allowing all three functions to execute after a 3-second delay. To stagger their execution at intervals of 3 seconds, you can modify the code like this:

function function0() {
    setTimeout(function1, 3000);
    setTimeout(function2, 6000);
    setTimeout(function0, 9000);
}

If you prefer not to hardcode the time intervals, you could utilize setInterval, incrementally change the function name (if they are numbered), and halt after a certain number of iterations:

var i = 0,
int = setInterval(function () {
    // Function logic
    i++;
    if (i === 3) {
        clearInterval(int);
    }
}, 1000);
