I am new to jQuery. I am trying jQuery autocomplete remote data source here is my code:

<?php

$q = strtolower($_GET["birds"]);
echo $q;
$return = array();
$query = "SELECT title

$resultset=mysql_query($query,$connection);

$json .= '{"value":"'.$row['title'].'"}';
}
$json .= ']';
echo $json;
?>
getting the following error:
Notice:
Undefined

on line 4
[
{"value":"chandrayaan"},
{"value":"Project Management System"},
{"value":"shoping cart"},
{"value":"hospital management system"}
]
fire bug show the following error while searching on that text box and there is no suggestion for search.
How to resolve this problem?
As per the comments, it appears that the first error was caused by looking for the wrong $_GET variable. Props to you for spotting that with Firebug and correcting it appropriately.
The reason that it is not filling in a value currently is because of the extra string echoed in front of the JSON. Remove the line echo $q; and it should work.

I'm unable to get one of my functions to work. My assumption is that there is a 'scope' issue due to the fact the function works when used in the same file it modifies. Anyway here is the function and fiddle.
The function as the title suggests should replace text on hover and 'off-hover' put the original text back. The code snippet below works, but when used as I'm trying to(fiddle) it does not work.

Several different questions on this topic, but none of the answers helped, so thought I'd try and see if anyone can figure this out..
So I have a simple grid, here is the HTML/PHP:

<? } ?>
$(".li_current_report").html("Raw Statistical Data");
$("#rawDataGrid").kendoGrid({

Here is the datasource code:
// Build SQL statement
$SQL_STATS = "

WHERE date_entered between '" . $FROM . "' AND '" . $TO . "' AND
action_detail1 NOT In(" . $excludeIPs . ") AND active = 1";
if ( is_numeric($_GET['source']) && trim($_GET['source']) != "" ){
$SQL_STATS .= "

}
$SQL_STATS .= "
ORDER BY date_entered DESC
";
// Get the data
$statResult = mysql_query($SQL_STATS); // Run the actual query.
$dataOut = array(); // Create empty array for temp data to store in main output array
while ( $stat = mysql_fetch_object($statResult) ) {
$dataOut[] = $stat;
}
header("Content-type: application/json");
echo "{\"data\":" . json_encode($dataOut). "}";
The output seems fine - and LINTs fine as well, here's a piece of it:
{"data":[{"comment":"Site Visit"},{"comment":"Site Visit"},{"comment":"Site Visit"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"Site Visit"},{"comment":"View Contact Information"},{"comment":"Site Visit"},{"comment":"View Contact Information"},{"comment":"Doctor Site Visit"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"Doctor Site Visit"},{"comment":"View Contact Information"},{"comment":"Site Visit"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"View Contact Information"},{"comment":"Doctor Site Visit"},{"comment":"View Contact Information"},{"comment":"Doctor Site Visit"}]}
But the grid isn't rendering. I've used several JSON validators. And the browser is seeing this output as APPLICATION/JSON.
Any ideas?
Thanks to all in advance!
I don't see where you are calling this method. generateRawDataGrid()
Perhaps you need to create a document.ready() function and call it from there.
$(document).ready(function () {
generateRawDataGrid();
});
I am pulling data from a mySql database using php to plot a graph using flot. The query works fine but no graph is being displayed when I run the code. A blank space is coming up where the graph should be. Here is what I have:

<?php

$sql="select name, age from `people` where age=23";
$results = $mysqli->query($sql);
if ($results)
{
while ($row=$results->fetch_assoc())
{
$dataset1[] = array($row['name'],$row['age']);
}
}
else
{
echo "Error";
}
?>
<script type="text/javascript">
var dataset1 = <?php echo json_encode($dataset1); ?>;
$(function ()
{
$.plot($("#placeholder"), [
{
data: dataset1,
bars: {show: true}
}
]);
});
</script>
</body>
</html>
It looks like your x values are strings, yet you haven't included the categories plugin.
Thanks everyone. I got it to work. I'm not sure what the problem was but it worked after I changed the javascript part to :
$(function ()
{
$.plot("#placeholder", [ dataset1 ], {
series: {
bars: {
show:true,
barWidth: 0.6,
align: "center"
}
},
xaxis: {
mode: "categories",
tickLength:0
}
});
});
I have trawled the net and Stack Overflow and have not found an adequate answer to this question. Before I start the trial and error process of finding my own solution, I thought I would turn to the Stack Overflow braintrust and see if there was already a successful implementation.
I have an AJAX powered page that degrades properly for non-javascript browsers and SEO. Each click in the AJAX version can be represented by a unique URL.
What I want to do is to dynamically change the HREF of the button. I do understand that this tag is converted to standard HTML at runtime (namely into a nasty table / iframe layout).
I was just wondering if anyone had any insight as to how to implement this FB like button onto AJAX powered pages?
Cheers in advance :)
EDIT:
What do you think of this method I just hacked together? See any huge problems with it?

SIMPLE SOLUTION
Just parse trigger the parse function when load complete.
If you’re using jQuery, there’s a real easy and slick solution to this problem:
$(document).ajaxComplete(function(){
try{
FB.XFBML.parse();
}catch(ex){}
});
http://developers.facebook.com/docs/reference/plugins/like/
This is the solution I ended up going with:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<script src="JS/jquery/jquery.js" type="text/javascript"></script>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<script language="javascript" type="text/javascript">
$("document").ready
(
function ()
{
CreateNewLikeButton("http://www.yahoo.com")
$("#ChangeToGoogle").click
(
function (e)
{
e.preventDefault();
CreateNewLikeButton("http://www.google.ca")
}
);
}
);
function CreateNewLikeButton(url)
{
var elem = $(document.createElement("fb:like"));
elem.attr("href", url);
$("#Container").empty().append(elem);
FB.XFBML.parse($("#Container").get(0));
}
</script>
</head>
<body>
<form id="form1" runat="server">
<a id="ChangeToGoogle" href="#">Change To Google</a>
<div id="Container">
<fb:like href="http://www.NEVER_LINK_TO_THIS_12345.com"></fb:like>
</div>
</form>
</body>
</html>
You're making this hard on yourself - just render a new iframe-based one.
<html>
<head>
<title>Test Page</title>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(function()
{
$( '#ChangeToGoogle' ).click( function( event )
{
event.preventDefault();
$( '#Container' ).empty().append( $('<iframe />')
.attr( 'src', 'http://www.facebook.com/plugins/like.php?href=www.google.com&layout=standard&show_faces=true&width=450&action=like&colorscheme=light&height=80' )
.attr( 'scrolling', 'no' )
.attr( 'frameborder', 'no' )
.attr( 'style', 'border:none; overflow:hidden; width:450px; height:80px;' )
.attr( 'allowTransparency', 'true' )
);
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<a id="ChangeToGoogle" href="#">Change To Google</a>
<div id="Container">
<iframe src="http://www.facebook.com/plugins/like.php?href=www.yahoo.com&layout=standard&show_faces=true&width=450&action=like&colorscheme=light&height=80"
scrolling="no" frameborder="0"
style="border:none; overflow:hidden; width:450px; height:80px;"
allowTransparency="true">
</iframe>
</div>
</form>
</body>
This is how I handled this situation when I ran into it - seems to work well.
// Set Facebook Like Button with jQuery
setFBLikeButtons = function (container,url,send,layout,width,show_faces,font) {
// Set Default Args
if(!send) { send = "false"; }
if(!layout) { layout = "button_count"; }
if(!width) { width = "100"; }
if(!show_faces) { show_faces = "false"; }
if(!font) { font = "arial"; }
$(container).empty(); // Remove current like button
$(container).html('<fb:like href="'+url+'" send="'+send+'"
layout="'+layout+'" width="'+width+'" show_faces="'+show_faces+'"
font="'+font+'"></fb:like>');
FB.XFBML.parse(); // This is the magical syrup
}
create like button
<head>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<script>
window.onload = function(){
var divs = document.getElementsByTagName("span");
for(var i=0; i<divs.length i++){
if(divs[i].className == "likes"){
if(divs[i].title){ var Href = divs[i].title; }else{ var Href = window.location; }
var fb_like = document.createElement("fb:like");
fb_like.setAttribute("href", Href);
fb_like.setAttribute("layout", "box_count");
fb_like.setAttribute("show_faces", "false");
fb_like.setAttribute("width", "55");
document.getElementById("likes2").appendChild(fb_like);
}
}
}
</script>
</head>
<body>
<span class="likes" title="www.bzzs.me"></span>
</body>
Load it after the window loads, this is what works for me:
$(window).load(function(){
$.getScript('http://connect.facebook.net/en_US/all.js', function() {
try{
FB.XFBML.parse();
} catch(ex) {}
});
});
If you're using the jQuery Mobile framework you can run the same code as the accepted answer in the pagecontainershow event which jQuery Mobile uses when it displays a new page.
// initialize new pages
$(document).on("pagecontainershow", (e, ui) =>
{
try
{
FB.XFBML.parse();
} catch (ex) { }
});
I was trying to create a notifications system for a website with the following code :
setInterval(function() {
$.post('notifications.php', {
email: 123
}, function(data) {
});
}, 30000);
And the notifications.php :
$userid = $_SESSION[username];
$notifications = array();
$sql = "SELECT appreciation FROM ms_notifications WHERE email = '$userid' AND new = '1'";
$res = mysql_query($sql) or die(mysql_error());
if (mysql_num_rows($res)) {
while ($r = mysql_fetch_object($res)) {
$notifications[] = $r->appreciation;
}
$nb_result = mysql_num_rows($res);
}
$sql = "UPDATE ms_notifications SET new = '0' WHERE email = '$userid'";
mysql_query($sql) or die(mysql_error());
echo $nb_result;
Problem is that, as I'm new to jquery/Js, I don't know how to put the result inside of a div. For now it stays on the top of the page, above everything.
I tried that, inside the data function but not working... :
$('#test_app').html(data);
I guess it's a very stupid question but help would be really appreciated ! Thank you very much.
UPDATE : Here the HTML Code
<?php
session_start();
include ('connection/database.php');
include ('login_script.php');
include ('notifications.php');
if($logged_in){
?>

Thanks again
Use .append() instead of .html()
Instead of
$('#test_app').html(data);
just use:
$('#test_app').html('<div>' + data + '</div>');
Seems to simple to be it. Am I missing something?
