Question

I have literally just started programing with Ajax and cant get this to work.

Here is what I have so far:

var oldAction = '';

function updateCheck() {
  $.ajax({
    url: 'check_status.php',
    success: function (data) {
      if (data.length != oldAction) {
        if (data.length == '4') {
          playSong();
        } else {
          pauseSong();
        }
      }

      oldAction = data.length;
    }
  });
}

setInterval('updateCheck();', 1000);

Does anyone know why this would not be working?

Thanks

Sure. length() is looking for an integer, but you are comparing it to a string.

If oldAction really needs to be a string, then you need to do something like this:

if (data.length != Number(oldAction)) {
  if (data.length == 4) {
    playSong();
  } else {
    pauseSong();
  }
};
