Start interval through timeout

Question

I have this piece of code that initially starts an interval. Then with the push of a button, I want that interval to be stopped/cleared, wait X seconds, and then start the interval again.

This code starts the interval and works fine:

var timeout = undefined;
var interval = setInterval(bgScroll, timeBetweenSwap);

Then I want the interval to be stopped when i click the button, let it wait X seconds and start again (ofcourse pressing the button again should reset that amount of seconds)

$(document).on('click', '.bgscroller a', function(){
    clearInterval(interval);
    clearTimeout(timeout);

    var timeout = setTimeout(function(){
        var interval = setInterval(bgScroll, timeBetweenSwap);
    }, delayAfterClick);
});

Now when i click the button a few times the interval goes crazy and stacks up. I would suggest it to be cleared... any advice oh how I should fix this?

Kind regards, Narayan

In short, remove the last two var statements. Make it timeout = and interval = instead of var timeout = and var interval =.

Your code is really close—it looks like you're shadowing the timeout and interval variables on the last few lines.

This is the bit that's wrong:

var timeout = setTimeout(function(){
    var interval = setInterval(bgScroll, timeBetweenSwap);
}, delayAfterClick);

It should look like this (very similar):

timeout = setTimeout(function(){
    interval = setInterval(bgScroll, timeBetweenSwap);
}, delayAfterClick);

Note that we removed the var statements. This uses the same timeout and interval variables like above, rather than making new variables that happen to have the same names.

Thank you so much Evan..! You have no idea how much time I've wasted on searching for answers :( — Narayan, Jan 17 '16 at 15:30
