I make div which refresh when file is updated. But it continuously refresh (fade out and fade in every second).I't source test2.php
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js>
</script>
<script>
$(document).ready(function() {
$('#loaddiv').load('check.chat.php');
});
var auto_refresh = setInterval( function() {
$.ajax(
{
type: 'POST',
data:"id=100",
url: "check.chat.php",
success: function(result)
{
if($("#loaddiv").html() != result)
{
$("#loaddiv").fadeOut("fast")
$("#loaddiv").html(result);
$("#loaddiv").fadeIn("slow");
}
}
});
}, 1000);
</script>
<div id="loaddiv"></div>
And file on site: **
Who knows what's the problem?
This part:
$("#loaddiv").fadeOut("fast")
$("#loaddiv").html(result);
$("#loaddiv").fadeIn("slow");
Should be:
$("#loaddiv").fadeOut("fast", function(){
$("#loaddiv").html(result);
$("#loaddiv").fadeIn("slow");
});
In your case, both fades are called at the same time, making an animation queue, causing it to go from one phase to another in about the same time the interval triggers again.
UPDATE
To see logs, do this: console.log("html: ", $("#loaddiv").html(), "result: ", result);

I ask you for help. Namely, struggling with the tooltip in ajax. Everything works beautifully when the page is load or after such as F5. However, in the part web I use refresh div every 60 seconds by ajax
<script type="text/javascript" >
$.ajaxSetup({ cache: false });
var auto_refresh = setInterval(
function()
{
$('#loaddiv').load('refresh_clusterdx_2.php');
}, 60000);
</script>
The code of my tooltip
<script type="text/javascript">
$(document).ready(function(){
function showProfileTooltip(e, id){
var top = e.clientY -45;
var left = e.clientX + 25;
$('.p-tooltip').css({
'top':top,
'left':left
}).show();
//send id & get info from get_prefix.php
$.ajax({
url: '/Info/get_prefix.php?id='+id,
beforeSend: function(){
$('.p-tooltip').html('Loading..');
},
success: function(html){
$('.p-tooltip').html(html);
}
});
}
function hideProfileTooltip(){
$('.p-tooltip').hide();
}
$('.profile').mouseover(function(e){
var id = $(this).attr('data-id');
showProfileTooltip(e, id);
});
$('.p-tooltip').mouseleave(function(){
hideProfileTooltip();
});
});
</script>
All beautifully and looks ok until the div is not refreshed. When a div to be refreshed, the tooltip no work :( I can not find a solution to the problem, whether it is at all possible to solve.
Thank you for any help.

To ensure that your functions work after ajax loaded content, you'll have to modify them a little:
$(document).on('mouseover', '.profile', function() {
var id = $('.profile').attr('data-id');
showProfileTooltip(e, id);
});
$(document).on('mouseleave', '.p-tooltip', function() {
hideProfileTooltip();
});
You should always use .on with dynamically loaded content - I'm in the habit of doing this for all my functions now.
I am trying to display a loading animation and hide the search input box before the ajax request has been sent, the ".se-pre-con" element is the loader.
As you can see below I am tring to show this in the beforeSend of the ajax request. However, when the user is typing in the search box then stops for the delay specified (1000ms) the input box still displays throughout the ajax request but it is unresponsive.
Then the results are returned, and the loading animation does the fadeOut so it the show() must be triggering but the page remains unchanged until the results are returned. I want to prevent the unresponsive page effect and show a loading animation during the request. Any help is much appreciated.
$(document).ready(function() {
var delay = (function() {
var timer = 0;
return function(callback, ms) {
clearTimeout(timer);
timer = setTimeout(callback, ms);
};
})();
$('#search_field').keyup(function() {
var target = $(this);
delay(function() {
getSearchResults(target.val());
}, 1000);
});
function getSearchResults(str) {
$.ajax({
beforeSend: function(){
$(".se-pre-con").show();
$("#search_field").hide();
},
url: "http://example.com/Search_Results.php",
dataType:"html",
data: {"search_term": str},
method: "post",
async: false,
success: function(data){
if(data !== null) {
$("#search_default").hide();
$("#search_results_wrapper").html(data);
}
$(".se-pre-con").fadeOut("slow");
$("#search_field").show();
$("#search_field").focus();
},
error: function(){
$(".se-pre-con").fadeOut("slow");
$("#search_field").show();
$("#search_field").focus();
}
});
}
});
I found the solution.
Solution
It started working when I removed the option:
async: false
I have PHP page called (jQuery_puff.php) which only holds a javascript/jQuery in it.
The jquery in that PHP is this:
<?php
echo '<script>
$( "#myButton" ).click(function() {
$( "#myDiv" ).effect( "puff", "slow" );
$( "#myDiv" ).toggle( "puff" );
});
</script>';
?>
I have included this PHP page within another PHP file like so:
<?php include "jQuery_puff.php"; ?>
what the first code inside the jQuery_puff.php does is that it will apply a jquery puff effect to the #myDiv everytime the user clicks on the #myButton.
Everything works as they should. so far so good. but this is only happens for one user (client side).
Now My Question:
Is there any way to run this PHP page in real time for all the users using AJAX?
For example the USER 1 clicks on the #myButton and the USER 2, USER 3 etc will also see the puff effect being applied to the #myDiv ?
I thought about using something like this But this doesn't do anything!!
<script type="text/javascript">
$(document).ready(function() {
$("#myButton").click(function() {
$.ajax({
url: 'myOwn.php',
cache: false,
success: function(data) {
checkForNewData2();
}
});
});
var intervalID2 = setInterval(checkForNewData2, 500);
});
function checkForNewData2() {
$.ajax({
url: 'jQuery_puff.php',
dataType: 'json',
cache: false,
success: function(data) {
$("#data").html(data.data);
}
});
}
</script>
am I in the right direction? or...?
I have a page that the function is to refresh div tag.
Div tag function is refresh the data will receive.
So far that's ok.
When I block the text using mouse, that's will clear the block text based on timing "20000". This below the JS script function.
<script src='js/jquery.min.js'></script>
<script>
$(document).ready(function()
{
$("#content2").load("post_rf.php");
var refreshId = setInterval(function()
{
$("#content2").load('post_rf.php?randval='+ Math.random());
}, 20000);
$.ajaxSetup({ cache: false });
});
</script>
What I want to do is, how to keep the block text in div refresh function ?
Because some user maybe want to copy the text. In this case, user must quickly copy the text before div refresh.
Maybe the example like facebook post live update.
You want to assign your interval to a variable, when user mouse overs your DIV then use clearInterval, when mouse out setInterval again.
var interval;
$(div).bind("mouseout", function() {
interval = setInterval(refresh, 1000);
});
$(div).bind("mouseover", function() {
clearInterval(interval);
});
EDIT
Sorry I posted that on a phone and it's hard to write code that way, try this:
<script src='js/jquery.min.js'></script>
<script>
$(document).ready(function() {
$("#content2").load("post_rf.php");
// set your initial interval to kick it off
var refreshInterval = setInterval(function() {
$("#content2").load('post_rf.php?randval='+ Math.random());
}, 20000);
// bind an event to mouseout of your DIV to kickstart the interval again
$("#content2").bind("mouseout", function() {
refreshInterval = setInterval(function() {
$("#content2").load('post_rf.php?randval='+ Math.random());
}, 20000);
});
// clear the interval on mouseover of your DIV to stop the refresh
$("#content2").bind("mouseover", function() {
clearInterval(refreshInterval);
});
$.ajaxSetup({ cache: false });
});
</script>
So I have a table pulling information from a database and I was wondering how I could make it refresh its information without reloading the whole page.
You'll need a getTable.php page that displays your table, and nothing else: no headers, footers, etc.
PHP (getTable.php) - this can be any server side code (asp, html, etc..)
<?php
echo '<table><tr><td>TEST</td></tr></table>';
?>
Then, in your JS, you can easily refresh the table by using the load() method:
HTML
<div id="tableHolder"></div>
JS
<script type="text/javascript">
$(document).ready(function(){
refreshTable();
});
function refreshTable(){
$('#tableHolder').load('getTable.php', function(){
setTimeout(refreshTable, 5000);
});
}
</script>
Use ajax, following example is in jQuery:
$(function() {
var prevAjaxReturned = true;
var xhr = null;
setInterval(function() {
if( prevAjaxReturned ) {
prevAjaxReturned = false;
} else if( xhr ) {
xhr.abort( );
}
xhr = $.ajax({
type: "GET",
data: "v1="+v1+"&v2="+v2,
url: "location/of/server/script.php",
success: function(html) {
// html is a string of all output of the server script.
$("#element").html(html);
prevAjaxReturned = true;
}
});
}, 5000);
});
The success function assumes that your server script outputs the html that you want to replace in the element with id 'element'.
You should have a page that return the information and pull data using Ajax / jQuery.
<div class="result"></div>
setInterval(function() {
$.get('table.php', function(data) {
$('#result').html(data);
});
}, 5000);
Here is another option for you to use. This solution is using an IIFE which is preferred over setInterval. You can read more about IIFE at the link above.
JAVASCRIPT:
var $results = $('#results'),
loadInterval = 5000;
(function loader() {
$.get('script.php', function(html){
$results.hide(200, function() {
$results.empty();
$results.html(html);
$results.show(200, function() {
setTimeout(loader, loadInterval);
});
});
});
})();
HTML:
<div id="results"></div>
setTimeout(function(){
jqueryFunction(Args);
},100);
will work...
100 = 100 milliseconds
The following works with JQuery Datatables 1.10
`var tableName;
//Set AJAX Refresh interval.
$(function() {
setReloadInterval(10); //Refresh every 10 seconds.
}
//Because function takes seconds we * 1000 to convert seconds to milliseconds.
function setReloadInterval(reloadTime) {
if(reloadTime > 0)
internalId = setInterval("reloadTable()", (reloadTime * 1000);
}
//Auto Refresh JQuery DataTable
function reloadTable() {
tableName.ajax.reload();
}
//Table defined...
$(document).ready(function () {
tableName = $('#tableName').DataTable({
"sAjaxSource": "/someUrl",
});`
