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>

<?php/*write by lizhi2009-10-26*/	$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-->

<?php/*	write by lizhi 	2009-10-26*/$json = array (  0 =>  array (   'id' => '13',   'name' => 'lizhi',  ),  1 =>  array (   'id' => '17',   'name' => 'admin',  ) );echo json_encode($json);?>
