如何在javascript中访问对象的内容?

当我做

$.each(result, function(i, n){
alert("key: " + i + ", Value: " + n );
});

然后我看到每个迭代

key: 276, Value: {"owners":["he"],"users":["he","m"],"end":"07/06-2011","groups":[],"type":"in"}

我如何访问每次迭代的ownersusersendgroupstype值?

在Perl中,我会完成

foreach my $key (keys %result) {
   print $result{$key}{owners};
   print $result{$key}{users};
   ...
}

更新

我从JSON那里得到了result

$.ajax({
    type: "GET",
    url: "/cgi-bin/ajax.pl",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: { "cwis" : id },
    // ...
    success: function(result){
    if (result.error) {
        alert('result.error: ' + result.error);
    } else {

        $.each(result, function(i, n){
        alert( "key: " + i + ", Value: " + n );

        });


    }
    }
});

它接缝的问题是服务器端不发送探测器JSON。

这是生成JSON字符串的服务器端脚本。

!/usr/bin/perl -T

use CGI;
use CGI::Carp qw(fatalsToBrowser);
use CGI qw(:standard);
use JSON;
use utf8;
use strict;
use warnings;

my $cgi = CGI->new;
$cgi->charset('UTF-8');

my $json_string = qq{{"error" : "The user do not have any activities."}};

my $json = JSON->new->allow_nonref;
$json = $json->utf8;

# @a and $act is now available

my $data;
foreach my $id (@a) {
    $data->{$id} = $json->encode(%{$act->{$id}});
}
$json_string = to_json($data);


print $cgi->header(-type => "application/json", -charset => "utf-8");
print $json_string;

document.write(result[key].owners);
document.write(result[key].users);

更新:

显然,我对这个问题的评论是这样回答的:

我不是CGI专家,但它看起来像是将数据双重编码为​​JSON。 一次

my $json = JSON->new->allow_nonref; $json = $json->utf8; 

然后再一次

$ data - > {$ id} = $ json-> encode(%{$ act - > {$ id}})。


$.each回调中, this指向当前元素,所以

$.each(result, function(i, n){
     alert(this.users);
});

n.owners or n['owners']
n.users or n['users']
etc.

在循环中...

$.each(result, function(k,v) {
    console.log("key: " + k + ", value: " + v );
    $.each(v, function(k,v)) {
        console.log("key: " + k + ", value: " + v );
    });
});
