This example uses the Jquery and Jquery Mobile application with HTML5 to send an asynchronous request to php on the server.
<!DOCTYPE HTML>
<html>
<head>
<title>Echo Machine</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.js"></script>
</head>
<body>
<div data-role="page" id="easyloader" data-theme="e" data-add-back-btn="true">
<div data-role="header">
<h1>Ajax Echo Machine</h1>
</div>
<div data-role="content">
<p> Test Jquery $.get function. Send an asynchronous request to the server and show results. </p>
<label for="echo_term"> Enter a phrase (and then press tab or click outside of box): </label>
<input type="text" name="echo_term" id="echo_term" onchange="makeEcho()"/>
</div>
<div id="echo_results" style="margin-left:50px" > Echo here. </div>
</div>
<script type="text/javascript">
function makeEcho() {
var echo_val=$("#echo_term").val();
$.get("scripts.php", {echo_term : echo_val}, function(data){
if (data.length>0){
$("#echo_results").html("<p> " + data + " </p>");
} else $("#echo_results").html('<p>no data returned! </p>');
});
}
</script>
</body>
</html>
uses the php file called scripts.php
<?php
//a simple echo machine the returns what you sent it.
$term = strip_tags(substr($_GET['echo_term'],0, 100));
$term = mysql_escape_string($term);
$term = "Response from php: " . $term;
echo $term;
?>
