我正在尝试构建一个简单的页面,通过JSON和jQuery查看保存在mysql数据库中的消息。
我的JSON是
{"unread_msgs":[{"id":"6","title":"33333","user1":"19","timestamp":"1383747146","client_id":"Generic"},{"id":"5","title":"42142","user1":"19","timestamp":"1383740864","client_id":"Generic"}],"read_msgs":[{"id":"4","title":"test to addnrow","user1":"19","timestamp":"1383676647","client_id":"Generic"},{"id":"2","title":"kll","user1":"19","timestamp":"1383675548","client_id":"Generic"},{"id":"1","title":"jkjljklj","user1":"19","timestamp":"1382539982","client_id":"Generic"}],"urm_t":2,"rm_t":3}
我的JS
<script type="text/javascript">
function GetClientMsgs () {
$.post("assets/server/client_msgs.php",{ client_id:local_client_id } ,function(data)
{
var MsgData = $.parseJSON(data);
console.log("Msg json data parsed");
$.each(MsgData, function(key, value)
{
console.log(value);
$('#unread_row').append('<td><a href="#read_pm" onClick="ReadMsg('+value.unread_msgs.id+'); return false;">'+value.unread_msgs.title+'</a></td><td><a href="#profile">'+value.unread_msgs.studioname+'</a></td><td>'+value.unread_msgs.timestamp+'</td><td><a href="#delete_msg" onClick="DeleteMsg('value.unread_msgs.id+'); return false;">X</a></td>');
$('#read_row').append('<td><a href="#read_pm" onClick="ReadMsg('+value.read_msgs.id+'); return false;">'+value.read_msgs.title+'</a></td><td><a href="#profile">'+value.read_msgs.studioname+'</a></td><td>'+value.read_msgs.timestamp+'</td><td><a href="#delete_msg" onClick="DeleteMsg('+value.read_msgs.id+'); return false;">X</a></td>');
});
});
}
</script>
PHP
$msgs = array('unread_msgs' => $dn1s, 'read_msgs' => $dn2s, 'urm_t' => $unread_msgs, 'rm_t' => $read_msgs);
$json = json_encode($msgs);
我正在尝试发布返回的值,例如unread_msgs.title或.id,并且无法访问任何对象。我在这里搜索过,找不到我的结构特有的东西。非常感谢。

我会循环遍历未读和读取结果,如下所示:
$.each(MsgData.unread_msgs, function(key, value)
{
// code append to unread row
console.log(value.id, value.title, "etc");
});
$.each(MsgData.read_msgs, function(key, value)
{
// append to append to read row
console.log(value.id, value.title, "etc");
});
将json粘贴到http://jsonformatter.curiousconcept.com/等格式化程序中可以帮助您查看其结构。

在这一行:
$('#unread_row').append('<td><a href="#read_pm" onClick="ReadMsg('+value.unread_msgs.id+'); return false;">'+value.unread_msgs.title+'</a></td><td><a href="#profile">'+value.unread_msgs.studioname+'</a></td><td>'+value.unread_msgs.timestamp+'</td><td><a href="#delete_msg" onClick="DeleteMsg('value.unread_msgs.id+'); return false;">X</a></td>');
您正在访问value
变量作为对象,而它实际上是一个数组。
要在$.each
循环中访问第一个未读邮件ID,您可以:value[0].id
。
如果您要获取未读和已读消息的列表,请尝试循环播放它们。
$.each(MsgData.unread_msgs, function(index, message) {
$('#unread_row').append('<td>' + message.id + '</td><td>.......');
});
$.each(MsgData.read_msgs, function(index, message) {
$('#read_row').append('<td>' + message.id + '</td><td>.......');
});
或者使用嵌套循环:
$.each(MsgData, function(key, value) {
$.each(value, function(index, message) {
$('#' + key).append('<td>' + message.id + '</td><td>....);
});
]);
