I was reading a lot of things about comet programming but I'm thinking if this implementation could be possible.
this is my jscript
$.ajax({
url:"mypage.php",
onProgress:{function(rsp){ //i know there is no such function like this
$("#mydiv").append(rsp+"<br>");
}}
});
and this is my mypage.php
<?php
while(true){
ob_start();
echo time();
ob_flush();
}
?>
now what i want is my ajax request would fetch results during progress. Is this possible?
for this thing to happen you have to use comet technique.... please refer
Heres the polling way todo it, if your only looking to grab the time. why have an infinite loop using resources.
<?php
//polling.php
if(isset($_GET['poll']) && $_GET['poll']=='1'){
$out = array('thetime'=>date("F j, Y, g:i:s a"));
echo json_encode($out);
die;
}
?>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script>
function poll(){
setTimeout(function(){
$.ajax({ url: "http://localhost/polling.php?poll=1",cache: false,
success: function(data){
//Do something with returned json
$("#time").replaceWith("<p id=\"time\">The Server Time & Date is: "+ data.thetime +"</p>");
//Next poll
poll();
}, dataType: "json"});
// 1/2 a sec
}, 500);
}
$(document).ready(function(){
poll();
});
</script>
<p id="time">The Server Time & Date is: <?php echo date("F j, Y, g:i:s a");?></p>
