You should pass a string for the url argument instead of an object:
$("div").load(this.href, function(){
alert("shod");
});

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.

I'm trying to pass a simple variable from my jQuery to my php and then echo it on my HTML. It doesn't seem to work though.
I can't get my variable $result to show up on my page. Any thoughts? The Ajax POST seems to be working fine. The problem seems to be communication between php and HTML.
index.html:
<!DOCTYPE html>
<html>
<head>
<title>My Site</title>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type='text/javascript' src='front.js'></script>
</head>
<body>
<?php echo $result; ?>
</body>
</html>
front.js:
$(document).ready(function() {
$.post('/back.php', {name: "Bob"}, function(data) {
});
});
back.php:
<?php $result = $_POST['name']; ?>
Try this
index.html:
<!DOCTYPE html>
<html>
<head>
<title>My Site</title>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type='text/javascript' src='front.js'></script>
</head>
<body>
</body>
</html>
front.js:
$(document).ready(function() {
$.post('/back.php', {name: "Bob"}, function(result) {
$('body').html(result);
});
});
back.php:
<?php echo $_POST['name']; ?>
Change this
<body>
<div id="show-data"></div>
</body>
And
$(document).ready(function() {
$.post('/back.php', {name: "Bob"}, function(data) {
$('#show-data').html(data);
});
});
And
<?php echo $result = $_POST['name']; ?>
Change Your PHP Code :
<?php echo $_POST['name']; ?>
And Also Your HTML Code :
<!DOCTYPE html>
<html>
<head>
<title>My Site</title>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
</head>
<body>
</body>
<script>
$(document).ready(function() {
$.post('/back.php', {name: "Bob"}, function(data) {
$('body').append(data)});
});
</script>
</html>
$result in back.php and $result in index.html aren't related. Setting it in back.php has no effect on index.html. If you echo something in back.php however, that output will be passed to the empty callback function you have in your $.post() call. You can handle the data there and use javascript to insert it into your page.
Just add the following line to your code: $('body').html(data);
Like your question we have three different files one is index.html
1) index.html
<!DOCTYPE html>
<html>
<head>
<title>My Site</title>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type='text/javascript' src='front.js'></script>
</head>
<body>
<?php echo $result; ?>
</body>
</html>
2) front.js
$(document).load(function(){
$.ajax({
url: '/back.php',
type: 'POST',
data: 'name=Bob',
async: false,
success: function(data) {
$('body').html(data);
},
cache: false
});
});
3) back.php
<?php echo $result = $_POST['name']; ?>
Now use this, your files will work out. Please let me know if you have any queries.
Puh, lot of mistakes. First, your index.html contains PHP - Code which won't be executed because this is not a PHP - Skript (ending with php).
Second you are saving the value of your request to back.php in a variable, which won't be existing after the request is finished. You can either:
rename index.html to index.php, exchange your statement to
<?php echo $_POST['name']; ?>
and change your request to
$.get('/index.php', {name: "Bob"}, function(data) {
});
which would cause a continously reloading of the site,
or store your result in a $_SESSION (see PHP Session Handling), and retrieve that in your index.php (you got to rename the file).
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:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

</head>
<body>
<h1>Flot Graph</h1>
<div id="placeholder" style="width:600px;height:300px;"></div>
<?php
$mysqli=new mysqli('localhost','root',"",'simpledb');
$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 am struggling with autocompletion via CodeIgniter. I followed a tutorial on http://www.codersmount.com/2012/09/jquery-ui-autocomplete-in-codeigniter-with-database/ .
I changed my database etc and the variables but when changing the database to one that not exists it doesn't gives any error so I guess it's something in the view itself but can't figure out what.
Thanks in advance

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

}
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.
