下面是我返回一字符串的ajax页面
a页面
$(document).ready(function(){
  $("#1").keyup(function(){
       $.post("action.php",{n1:$("#1").val(),n2:$("#1").val()},function(result){
      alert(result)
    });
   
  });
});
action.php页面

$txt=$_POST['n1'];
echo 'this  sw from page b, input is '.$txt.$_POST['n2'];
?>

现问:现需通过action.php页面得到一个php二维数组,在a页面可alert出一个js二维数组,应该如何实现呀,(解答时可用测试数据)thanks


回复讨论(解决方案)

alert(二维数组) 的话结果会是 array

可以返回json格式数据。

与JS的交互以后都尽量的采用json数据格式.
php  可以直接使用函数输出这个json内容.

$(document).ready(function(){
  $("#1").keyup(function(){
  $.post("action.php",{n1:$("#1").val(),n2:$("#1").val()},function(result){
  alert(result.n1+' '+result.n2);
  },'json');
    
  });
});
action.php页面

$txt=$_POST['n1'];

echo json_encoding(array('n1'=>$_POST['n1'],'n2'=>$_POST['n2']));
exit;
?>

echo json_encode(array(array('a'=>'b'),array('c'=>'d')));


alert(result[0][a]);

没测试,应该是这样的
