Ajax with jQuery
Let's implement this very simple Ajax example:
jQuery
Client-side
<html>
<head>
<title>Ajax example</title>
<script src="https://code.jquery.com/jquery-3.1.0.min.js"></script>
<script>
function DoDearch()
{
// This is the Ajax call to "getdata.php"
$.ajax({
method: "GET",
url: "getdata.php",
data: { searchValue: $('#searchValue').val() }
})
// And this handles the response
.done(function( response ) {
// Write response to our "results" element
$( "#results" ).html(response);
});
}
</script>
</head>
<body>
<h1>Ajax example</h1>
Enter value: <input type="text" id="searchValue">
<input type="button" value="Search" onclick="DoDearch();">
<p id="results"></p>
</body>
</html>
Server-side
<?php // Retreive value passed from Ajax call $searchValue = $_GET['searchValue']; // Debug message echo "Performing search for ".$searchValue."..."; // Connect to database // Build SQL statement // Run SQL statement // Loop through results and display ?>
