hi i have a html file which use ajax for loading contents from other html files in the same server. for some reason it does not work?? i have no clue as i am new to ajax.
here is the index.html(default home page)

<div class="clear"></div>
<div id="pageContent">

</div><div class="clear"></div>
<img src="img/bottom_bg.gif" alt="bottom" /></div>
</body>
</html>
script.js(for adding hash in the url and enable back button and also loading content)
ar default_content = "";
$(document).ready(function () {
checkURL();
$('ul li a').click(function (e) {
checkURL(this.hash);
});
default_content = $('#pageContent').html();
setInterval("checkURL()", 250);
});
var lasturl = "";
function checkURL(hash) {
if (!hash) hash = window.location.hash;
if (hash != lasturl) {
lasturl = hash;
if (hash == "")
$('#pageContent').html(default_content);
else
loadPage(hash);
}
}
function loadPage(url) {
var datastring = url.replace('#', '');
$('#loading').css('visibility', 'visible');
$.ajax({
type: "POST",
url: "load_page.php",
data: 'datastring=' + datastring,
dataType: "html",
async: false,
success: function (msg) {
if (parseInt(msg) != 0) {
$('#content').html(msg);
$('#loading').css('visibility', 'hidden');
}
}
});
}
and load_page.php
<?php
$url = $_REQUEST['datastring'];
echo $url;
if(file_exists(''.$url.'.html')){
echo file_get_contents(''.$url.'.html');
}
else{
echo 'There is no such page!';
}
?>
need help! as you can see when the ajax calls the "pagecontent" div loads the content from the requested page, but nothing happens here! what am i doing wrong?
Looks like you have "#content' in the ajax response handler... should be '#pageContent' to match the div id. That is:
success: function (msg) {
if (parseInt(msg) != 0) {
$('#pageContent').html(msg);
$('#loading').css('visibility', 'hidden');
}
}

Below is the Controller:
<?php
class Message extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->model('MessageDb');
$this->load->model('UserDb');
$this->load->model('EmployeeDb');
}
public function messageCount()
{
echo '12345'; //This is the dummy value.
}
}
?>
I want to display the count from Message controller into the view, it is not working. I tried a lot but not able to rectify the problem. How this can be done?
I have a script code to upload photos on imgur using AJAX. But I can not hide the Client-ID of the public.
I think I need to use PHP to do that use this code:
<?php $idClient = "abc12abc12abc";
echo $idClient ;
?>
But it turned Client-ID is still visible when in view its source code.
Here's the full code:

}
</style>
</head>
<body>

<div id="image_preview"></div>
<h2>Image On Imgur:</h2>

var reader = new FileReader();
reader.onload = function(e) {
var data = e.target.result.substr(e.target.result.indexOf(",") + 1, e.target.result.length);
$("#image_preview").html("<img src='" + e.target.result + "' />");
$.ajax({
url: 'https://api.imgur.com/3/image',

},
success: function(response) {
$("#image_preview_2").html("<img src='" + response.data.link + "' />");
}, error: function() {
alert("Error while uploading...");
}
});
};
reader.readAsDataURL(this.files[0]);
});

What's the solution?
I read all other question but nothing really helped.
I have one page with display and other php files supporting it but when I pass a POST and make a $_SESSION['view'] out of it with another POST request but not same one the $_SESSION['view'] is gone.
So in practic when user change view from four months (default) to one month and then click NEXT view gets back to four months.

<?php
session_start();
$dateb = (new DateTime())->getTimestamp();
$_SESSION['usrdate'] = $dateb;
?>

I am trying to update part of my HTML every second and fetching data from database into that Div but the code is not working. :( Please help. The first section of code is html page where update function is called and ajax call is made on check_status.php and check_status.php fetches the data from php file from database
<html>
<head>
<title>Reloading testing</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
var statusIntervalId = window.setInterval(update, 1000);
function update() {
$.ajax({
url: 'check_status.php',
dataType: 'text',
success: function(data) {
if (parseInt(data) == 0) {
$("#status").css({ color: "red" }).text("offline");
} else {
$("#status").css({ color: "green" }).text("online");
}
}
}
}
</script>
</head>
<body>
<h1>Refresh part of the page</h1>
<div id="status">
</div>
</body>
</html>
This is check_status.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</head>
<body>
<?php
$con = mysql_connect("localhost", "root", "");
mysql_select_db("manchesterunited", $con);
$row = mysql_fetch_array(mysql_query("SELECT * FROM players LIMIT 1"));
mysql_close($con);
echo $row[0]; ?>
</body>
</html>
}
You have a syntax error related to parentheses. Try this:
function update() {
$.ajax({
url: 'check_status.php',
dataType: 'text',
success: function(data) {
if (parseInt(data) == 0) {
$("#status").css({ color: "red" }).text("offline");
} else {
$("#status").css({ color: "green" }).text("online");
}
}
}); // properly end the ajax() invocation
}
You should be able to fix syntax problems yourself with the help of errors reported on the javascript console.
This script is supposed to run a jQuery Ajax script every second, it is supposed to fetch all newer posts then put them on top of the original ones. But at the moment nothing is happening, it loads the initial posts but nothing else. Firebug console is reporting no errors, or no Ajax requests being sent at all. Can you see anything wrong with this script at all that could cause this? Thanks :)

Some of the code in the beginning looks wrong. This should work. It will call the oneSecondFunction every second:
$(document).ready(function() {
setInterval(oneSecondFunction, 1000);
function oneSecondFunction() {
//console.log('run oneSecondFunction');
var ID = $(this).attr("id");
if(ID) {
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({ type: "POST", url: "ajax_more.php", data: "lastmsg="+ ID, cache: false,
success: function(html){
$("ol#updates").prepend(html);
$("#more"+ID).remove();
}
});
} else {
} return false; };
});
i quoted out the section where it gets the id, because 'this' wasn't referring to anything.
<script type="text/javascript">
$(function() {
setInterval(oneSecondFunction, 1000);
});
function oneSecondFunction() {
//var ID = $(this).attr("id");
var ID = '1';
if(ID){
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "ajax_more.php",
data: "lastmsg="+ ID,
cache: false,
success: function(html){
$("ol#updates").prepend(html);
$("#more"+ID).remove();
}
});
}
return false;
}
</script>
