I have this script
say index.html

<script type="text/JavaScript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
setInterval(function(){
$("#quote p").load("script.php");
}, 10000);
});</script>
<style type="text/css">
#wrapper {
width: 240px;
height: 80px;
margin: auto;
padding: 10px;
margin-top: 10px;
border: 1px solid black;
text-align: center;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="quote"><p> </p></div>
</div>
</body>
</html>
script.php
<?php
echo "Hello how are you";?>
when loading index.html it is blank for 10 seconds and then it start functioning..how do I get rid of blank and how it can show instantly when browser loads??
Your setInterval() call works as designed: It says "in 10 seconds and then every seconds, do this...."
Add a separate "load" call to do the initial filling:
$(document).ready(function(){
$("#quote p").load("script.php"); // <--- Add this
setInterval(function(){
....

I have this php page that rungs its script.
From the index page the user clicks a button and this page, after 10 seconds or so, shows the final result.
I would like to show a progress bar while the user waits.
This is the actual page:
<!DOCTYPE html>
<html>
<head>
<title>METAR LIRN</title>
<style>
h1 {
text-align: center;
}
.table {
display: table;
margin-top: 30px;
margin-left: auto;
margin-right: auto;
border: 1px solid #808080;
padding-left: 30px;
padding-right: 30px;
padding-bottom: 10px;
}
</style>
</head>
<body>
<div class="table">
<div>
<h1>METAR LIRN<h1>
</div>
<div>
<?php
$output = shell_exec('sh /var/www/html/weather.sh');
echo "<pre>$output</pre>";
?>
</div>
</body>
</html>
I had a look to other similar posts with no luck...
Thanks in advance!

I am trying to make a image sticker html 5 app. In which user uploads a photo and then places stickers on top of it. I am able to do it through HTML 5 canvas and Jquery library free transform to rotate and scale stickers on top of image but when i convert this into jpeg the css transaction is lost and only image with stickers on top is generated. Code is written below. Is there any other way to do it?

It's the divs you have inside of your div that seem to be causing an issue. I commented them on on this jsFiddle http://jsfiddle.net/ta9N4/ and it appears to be working fine.
The method resizable() comes from jQuery UI API.
And you didn't include jQueryUI in your html page.
Go here to download it (or grab a link to this file), and include it like you did for jQuery (<script> tag).
I do have a ajax code will work on a click of button. but I need it should automatically load function in between every 10 seconds. how can I rewrite below code??
<html>
<head>
<title>Ajax with jQuery Example</title>
<script type="text/JavaScript" src="jquery.js"></script>
<script type="text/JavaScript">
$(document).ready(function(){
$("#generate").click(function(){
$("#quote p").load("script.php");
});
});
</script>
<style type="text/css">
#wrapper {
width: 240px;
height: 80px;
margin: auto;
padding: 10px;
margin-top: 10px;
border: 1px solid black;
text-align: center;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="quote"><p> </p></div>
<input type="submit" id="generate" value="Generate!">
</div>
</body>
</html>
$(document).ready(function(){
setInterval(function(){
$("#quote p").load("script.php");
}, 10000);
});
This will call $("#quote p").load("script.php") (or more accurately, the anonymous function that contains this call) every 10 seconds (the second argument to setInterval is specified in milliseconds).
You should be able to do this:
setInterval(function () {
$("#quote p").load("script.php");
}, 10000);
Which will load script.php every 10 seconds into $('#quote p').
