I want a div to refresh automaticallywithout refreshing whole page

I have developed a comment system with ajax and its working fine. I want to add a ajax/js code to refresh my time ago div after every 5 seconds so that the time changes while one is on same post.
Please note:
Sir, i just want code to request server to refresh div after a specific time period. I do not want to load page or div but i want contents within that div should be refreshed after a specific period of time.
I'm new in js/ajax and Ii tried this but not working yet
$(document).ready(function () {
setInterval(function () {
$("#showtimeago!").load();
}, 1000);
});
Result I want is:
<div class="p_timeAgo" id="showtimeago"> <?php time_stamp($timePost);?></div>
Can anyone help me to solve that issue?

I don't know what UI you are using, here is for the php(since Jquery is same) you can tune this up for your requirement.
function loadlink(){
$('#showtimeago').load('test.php',function () {
$(this).unwrap();
});
}
loadlink(); // This will run on page load
setInterval(function(){
loadlink() // this will run after every 5 seconds
}, 5000);
Try this:
<div id="showtimeago"></div>
setInterval(function(){
$('#showtimeago').load('test.php');
},5000);
test.php is the page the refresher stand.

show loading on jquery refresh

I have this JQuery code that loads a php file into a div every X Seconds
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">// <![CDATA[
$(document).ready(function() {
$.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh
setInterval(function() {
$('.container').load('dashboard.php');
}, 10000); // the "3000" here refers to the time to refresh the div. it is in milliseconds.
});
// ]]></script>
<div class="container"><h3>Loading Dashboard...</h3></div>
when the loading starts it shows the Loading Dashboard text but then every X seconds it just refreshes the content in the background. how can i show some sort of loading image each time it refreshes?

How about this:
1) at the very top of your setInterval function, before you execute the load, set the background of that container class to be a loading image (or however you want to display it).
2) use the callback function of .load (https://api.jquery.com/load/) to remove that loading image when the load has completed.

Here's a fiddle illustrating the direction you should take...
http://jsfiddle.net/j5sZc/
HTML
<div class="wrapper">
<h3 class="loader">Loading Dashboard...</h3>
<div class="container"></div>
</div>
JS
$(document).ready(function() {
$.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh
var $loader = $(".loader"), // cache references to loader and container
$container = $(".container");
setInterval(function() {
$loader.show(); // show loader when request is initialized
$container.empty().load('dashboard.php', function(){
$loader.hide(); // hide loader once new content is loaded
});
}, 10000); // the "3000" here refers to the time to refresh the div. it is in milliseconds.
});

Javascript refresh php page when previous refresh has finished

I am using this code to refresh a PHP page:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">// <![CDATA[
$(document).ready(function() {
$.ajaxSetup({ cache: false }); // This part addresses an IE bug. without it, IE will only load the first number and will never refresh
setInterval(function() {
$('.container').load('integra_data.php');
}, 2000); // the "3000" here refers to the time to refresh the div. it is in milliseconds.
});
// ]]></script>
<div class="container"><h3>Loading Data...</h3></div>
in javascript, rather than refreshing every X Seconds, can i make it refresh once the previous refresh has finished?

Use setTimeout instead setInterval.

$(document).ready(function() {
$.ajaxSetup({ cache: false });
setTimeout(function() {
$('.container').load('integra_data.php');
}, 2000);
});
$( document ).ready(function(){}) everything inside of this will be ran after load of page has finished. so there should be delay of 2 seconds here..

If I got you right you want to refresh the content of the div in an infinite loop, right? If this is right, you could pass your call to load() as complete callback. You could do somethin like this (recursion):
$(document).ready(function() {
var loadFunction = function () {
$('.container').load('integra_data.php', loadFunction);
}
$.ajaxSetup({ cache: false });
loadFunction();
});
The loadFunction() will call itself every time the last run has finished. Refer to the docs if you want to know more about the complete callback. If you add a little delay, since it's not always the best idea to make request as fast as possible use the setTimeout() function. You could add it to the complete callback.

Reload a DIV without reloading the whole page

I have a Div Tag that has a php include to fill that div with information
what I want to do is make it so that the page is called every 15s so it can update the information there without having to reload the whole webpage.
I've tried to do this with JavaScript/jQuery and I just can't seem to get it to work
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript">
var auto_refresh = setInterval(
function ()
{
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
</script>
<div class="View"><?php include 'Small.php'; ?></div>
this is what I have after searching some, and what happens is, it loads the Small.php but it doesn't refresh it or update the info every 15 seconds.
please help!
I should add all my php arrays that should show up are all executed in the Small.php and the page I'm including it into is just so it's isolated.
EDIT: What No One noticed was that my first script referencing jQuery did not have a closing tag, and that was breaking my second script. after adding in a proper closing tag, the script was finally working, but the fadeIn does not show properly without first using a fadeOut.

Your code works, but the fadeIn doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut → load → fadeIn:
var auto_refresh = setInterval(function () {
$('.View').fadeOut('slow', function() {
$(this).load('/echo/json/', function() {
$(this).fadeIn('slow');
});
});
}, 15000); // refresh every 15000 milliseconds
Try it here: http://jsfiddle.net/kelunik/3qfNn/1/
Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax and $.ajaxSetup ({ cache: false }); or the random-hack, he mentioned.

try this
<script type="text/javascript">
window.onload = function(){
var auto_refresh = setInterval(
function ()
{
$('.View').html('');
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
}
</script>

Your html is not updated every 15 seconds. The cause could be browser caching. Add Math.random() to avoid browser caching, and it's better to wait until the DOM is fully loaded as pointed out by #shadow. But I think the main cause is the caching
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
$(document).ready(function(){
var auto_refresh = setInterval(
function ()
{
$('.View').load('Small.php?' + Math.random()).fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
});
</script>

The code you're using is also going to include a fadeout effect. Is this what you want to achieve? If not, it might make more sense to just add the following INSIDE "Small.php".
<meta http-equiv="refresh" content="15" >
This adds a refresh every 15seconds to the small.php page which should mean if called by PHP into another page, only that "frame" will reload.
Let us know if it worked/solved your problem!?

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<div class="View"><?php include 'Small.php'; ?></div>
<script type="text/javascript">
$(document).ready(function() {
$('.View').load('Small.php');
var auto_refresh = setInterval(
function ()
{
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
$.ajaxSetup({ cache: true });
});
</script>

Refresh DIV contents every x seconds WITHOUT eternal page?

Here's an example:
<script type="text/javascript">
var auto_refresh = setInterval(
function ()
{
$('#photos').load('photos.php').fadeIn("slow");
}, 5000); // refresh every 10000 milliseconds
</script>
<div id="photos"></div>
The problem is the complexity of the other javascript on the page isn't really ideally for reloading the div from an external page. If it's the only way, I'll backtrack and work that out... I was just wondering if it's possible to refresh the div contents from the page itself?

You can read the whole page, then extract the element you're looking for:
$('#photos').load('YourPage.php#photos');
The server will still send the entire page to the client.

function refreshDiv(){
$('#photos').load('photos.php').fadeIn("slow");
setTimeout("do_again()", 5000)
}
function do_again(){
refreshDiv();
}
That would keep loading your jQuery every 5 seconds (5000ms).
