超时功能完成后如何调用函数？

Question

I have a function with a timer, I want to call another function when the timer of the another function is done, so the first function will show a modal for 3 seconds, and the another funciton will show another modal, here is my code:

var fn = setTimeout(function(){
    $('#responseModal').modal('hide');
    return true;
}, 3000);

if(fn)

    $('#requestModal').modal('show');

Answer 1

Wouldn't

setTimeout(function(){
    $('#responseModal').modal('hide');
    $('#requestModal').modal('show');
}, 3000);

do the trick?

No need to return anything in the callback function for setTimeout . It's meaningless.
