页面代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JSONP 实例</title>
<script src="http://cdn.static.runoob.com/libs/jquery/1.8.3/jquery.js"></script>
</head>
<body>
<div id="divCustomers"></div>
<script>
$.getJSON("http://www.runoob.com/try/ajax/jsonp.php?jsoncallback=?", function(data) {
var html = '<ul>';
for(var i = 0; i < data.length; i++)
{
html += '<li>' + data[i] + '</li>';
}
html += '</ul>';
$('#divCustomers').html(html);
});
</script>
</body>
</html>
客户端实现 callbackFunction 函数：
<script type="text/javascript"> function callbackFunction(result, methodName) { var html = '<ul>'; for(var i = 0; i < result.length; i++) { html += '<li>' + result[i] + '</li>'; } html += '</ul>'; document.getElementById('divCustomers').innerHTML = html; } </script>
服务器端代码：
<?php header('Content-type: application/json'); //获取回调函数名 $jsoncallback = htmlspecialchars($_REQUEST ['jsoncallback']); //json数据 $json_data = '["customername1","customername2"]'; //输出jsonp格式的数据 echo $jsoncallback . "(" . $json_data . ")"; ?>
