半个小时学json(json传递示例)

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
	$(document).ready(function(){
		$.getJSON("a.php",{id:1, name:encodeURI('李智'), gender:encodeURI('男')},function(json){
					var json=eval(json);
					var html = '<select>'
          html += '<option value="' +json['id']+'">'+decodeURI(json['name'])+'</option>';
					html += '</select>';
					html += '<span>'+json['gender']+'</span>';
					$('#aa').html(html);
		});
	});
</script>
<div id="aa"></div>

	$id = $_GET['id'];
	$name = $_GET['name'];
	$gender = $_GET['gender'];
	$arr2 = array("id"=>$id, "name"=>urldecode($name), "gender"=>urldecode($gender));
	echo json_encode($arr2);
?>

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
	$(document).ready(function(){
		$.getJSON("a.php",{id:1, name:'admin', gender:'男'},function(json){
					var json=eval(json);
					var html = '<select>'
					$.each(json, function(k) 
          {
            html += '<option value="' +json[k]['id']+'">'+decodeURI(json[k]['name'])+'</option>'; 
          });
					html += '</select>'
					$('#aa').html(html);
		});
	});
</script>
<div id="aa"></div>

<!--利用jquery返回json数组，返回的为二维数组，所以需要遍历输出
未解决中文传递问题-->

$json = array ( 
 0 => 
 array ( 
  'id' => '13', 
  'name' => 'lizhi', 
 ), 
 1 => 
 array ( 
  'id' => '17', 
  'name' => 'admin', 
 )
 );
echo json_encode($json);
?>
