json跨域访问数据---备忘

服务端（数据源端）：

<?php
$arr = array('name' => 'dc,'nick' => '指尖,'content' => array('email' => '[e-mail]','website' => 'http://dcdc723.iteye.com',));
$callback = empty ( $_GET ['jsoncallback'] ) ? empty ( $_POST ['jsoncallback'] ) ? '' : addslashes ( $_POST ['jsoncallbacklback'] ) : addslashes ( $_GET ['jsoncallback'] );
exit ( $callback . "(".json_encode($arr).")" );
?>
    

 客服端：

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
$(function() {//by dcdc723 http://dcdc723.iteye.com
	   	$.getJSON("服务端地址?jsoncallback=?",   //by dcdc723 http://dcdc723.iteye.com
			  function(data){
				$("#data").html(data.name+data.nick+data.contact.email); 
				 document.getElementById("cont").innerHTML=data.content.email;
			  });		 
});
</script>
<div id="cont">a</div><br>
<br>
<br>
<div id="data"></div>

  $.getJSON()的第一个参数中的地址中须跟参数jsoncallback=?对应服务端参数
