Question

I have a site that plays a stream. I perform an AJAX call to the server once a person presses a button.

<input type="submit" class="play" data-type="<?php echo $result_cameras[$i]["camera_type"]; ?>" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>">

This prints out a bunch of buttons that the user can select. This is processed by the following code:

<script>
$(document).ready(function(){

$(".play").on('click', function(){
    var camerahash = $(this).data('hash');
    var cameratype = $(this).data('type');
    function doAjax(){
        $.ajax({
            url: 'index.php?option=streaming&task=playstream&id_hash=<?php echo $id_hash; ?>&camera_hash='+camerahash+'&format=raw',
            success: function(data) {
                if (data == 'Initializing...please wait')
                {
                    $('#quote p').html(data); //shows a message here
                    setTimeout(doAjax, 2000);
                }
                else
                {
                    if (cameratype == "WEBCAM" && data == 'Stream is ready...')
                    {
                        $('#quote p').html(data); //another message here
                        window.location = 'rtsp://<?php echo DEVSTREAMWEB; ?>/<?php echo $session_id;?>/'+camerahash;
                    }
                    else if (cameratype == "AXIS" && data == 'Stream is ready...')
                    {
                        $('#quote p').html(data); //another message here
                        window.location = 'rtsp://<?php echo DEVSTREAMIP; ?>/<?php echo $session_id;?>/'+camerahash;
                    }
                    else
                    {
                        $('#quote p').html(data); //another message here
                    }

                }

            }
        });

    }
    doAjax();
});
});
</script>

Everything works as the user gets messages when they click a button. But clicking another button doesn’t show the messages any more. I’ve used the delegate event (.on) for dynamically loaded buttons (instead of .click()) which I thought would address this but it looks like I just don’t get what I need to do.

To start off you need to specify a selector within .on. In your case if you don’t have a parent/ancestor you can specify document.

 $(document).on('click', '.play', function(){....
