我在我的管理面板中实现了一个日志表,我使用了数据表插件。 我在我的数据表中创建了一个 ajax,但我不知道如何在发送到表之前获得响应。
我的 jquery 中有这个:
<script type="text/javscript">
$(document).ready(function() {
$('#log-pageview')
.on('xhr .dt', function(e, settings, json) {
$('#status').html(json.status)
})
.dataTable({
"processing": true,
"serverSide": true,
"ajax": "/secure/logs/visits.php?log_get=1"
});
});
</script>
在我的 HTML 中我有这个:
<table id="log-pageview" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Log ID</th>
<th>User ID</th>
<th>IP Address</th>
<th>Date Viewed</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Log ID</th>
<th>User ID</th>
<th>IP Address</th>
<th>Date Viewed</th>
</tr>
</tfoot>
</table>
<div id="status"></div>
在我的服务器端 PHP 中有这个。
function get_pageview() {
$host = mysql_connect('localhost','avjunky_2','1qaz2wsx') or die(mysql_error());
mysql_set_charset('utf8', $host); //added for character encoding, made it global for functions /** added by rochelle **/
$db = mysql_select_db('avjunky_2',$host) or die(mysql_error());
$log_array = array();
$log_data = array();
$get_all_logs = mysql_query("SELECT id, logged_id, ip_address, date_viewed FROM avjunky_pageview", $host);
while($row_logs = mysql_fetch_array($get_all_logs)) {
$log_data[] = array(
'id' => $row_logs['id'],
'logged_id' => $row_logs['logged_id'],
'ip_address' => $row_logs['ip_address'],
'date_viewed' => $row_logs['date_viewed']
);
}
$total_count = count($log_data);
$log_array = array(
'draw' => 1,
'recordsTotal' => $total_count,
'recordsFiltered' => $total_count,
'data' => $log_data
);
echo json_encode($log_array);
}
if(isset($_GET['log_get'])) {
get_pageview();
}
在服务器端我生成了这种 json:
{"draw":1,"recordsTotal":2,"recordsFiltered":2,"data":[{"id":"3","logged_id":"7","ip_address":"122.2.55.11","date_viewed":"2015-03-16 10:10:42"},{"id":"2","logged_id":"8","ip_address":"122.2.55.11","date_viewed":"2015-03-17 00:05:40"}]}
{
"draw":1,
"recordsTotal":2,
"recordsFiltered":2,
"data":[
{
"id":"3",
"logged_id":"7",
"ip_address":"122.2.55.11",
"date_viewed":"2015-03-16 10:10:42"
},
{
"id":"2",
"logged_id":"8",
"ip_address":"122.2.55.11",
"date_viewed":"2015-03-17 00:05:40"
}
]
}
我不知道我哪里做错了。我检查了开发人员工具网络选项卡,似乎 ajax 没有调用 URL。
在我的 AJAX 中,我也尝试像这样从 URL 调用响应。
http://mysite/admin/secure/logs/visits.php?log_get=1
但它也不会加载数据。
最佳答案
首先,要使用 xhr.dt
数据表 > 应该使用 1.10。
其次,数据应具有以下结构。
{
"draw":1,
"recordsTotal":2,
"recordsFiltered":2,
"data":[
[
"3",
"7",
"122.2.55.11",
"2015-03-16 10:10:42"
],
[
"2",
"8",
"122.2.55.11",
"2015-03-17 00:05:40"
]
]
}
这是一个demo
