jquery polling with smart poll plugin

Question

I'm trying for the life of me to get this plugin to work but I'm not understanding the status function so retry is not firing.

$.poll(10000, function(retry){
  $.get('willfail', function(response, status){
    if (status == 'success') {
      // Do something
      alert("YES");
    } else {
      alert("NO");
      //retry();
    }
  })
})

If I set the get request to '/' it will give me the alert YES message, but as it is, the alert No message never gets fired despite the ELSE.

I'm using a jquery polling plugin:

Any ideas?

The code in `// Do something` may be silently failing so you never get to `alert("YES");` but also don't see `alert("NO");`. — justkt, Apr 14 '11 at 15:15

You can also use Smartupdater - jQuery plugin

http://www.eslinstructor.net/smartupdater/

which let you:

Stop/Restart polling
Change polling timeout dynamically
Switch polling URL dynamically
Switch callback function dynamically
Remotely set polling timeout
Remotely select callback function

That is probably a bad example. The callback passed to $.get will only be fired if the request succeeded. Try this:

$.poll(10000, function(retry){
  $.ajax({
      url:'willfail',
      success: function(){
          // Do something
          alert("YES");
      },
      error: function() {
          alert("NO");
          retry();
      }
  });
});

For more information, have a look at $.ajax.
