clearInterval / setInterval

Question

I am using the following script to display jpg images as an animation:

var interval;

function Play() {
  setInterval(Playimages, 100);
}

function Stop() {
  alert("stop");

  clearInterval(interval);
}

function Playimages() {
  i = (i < sl - 1) ? (i + 1) : 0;

  $('#Image1').attr('src', images[i].src);
}

Play works well, however I can not stop or pause; there is a mistake in my clearInterval. Would appreciate your suggestions. Thanks

Answer 1

You never assign the interval id to interval . Should be

interval = setInterval(Playimages, 100);

Answer 2

You need to change

 setInterval(Playimages, 100);

to

interval = setInterval(Playimages, 100);

setInterval returns an id which can be used with clearInterval . In your code interval is probably undefined, so clearInterval does nothing because it has no reference.

Answer 3

You need to assign the interval id to interval .

var interval;

function Play() {
  interval = setInterval(Playimages, 100);
}

Answer 4

You have to assign the interval variable in setInterval

interval = setInterval(Playimages, 100);
clearInterval(interval);
