我有这个代码:messages.php
if (count($row) > 0)
{
foreach ($row as $r)
{
//some code setting variables
if ($opened_once >= 1)
{
}
else
{
echo "<tr>";
echo '<td><a class="red_link" href="'.ADDRESS.'view_message.php?id='.$r['id'].'" id= "subject_id" ><span id = "subject">'.$r['subject'].'</span></a></td>';
echo '<td id = "unique_code1">'.$uniqueCode1.'<span class="pink_text" id = "unique_code2">'.$uniqueCode2.'</span><span id = "unique_code3">'.$uniqueCode3.'</span></td>';
echo "</tr>";
}
}
我需要更新$r['id']
,$r['subject']
,$uniqueCode1
,$uniqueCode2
,$uniqueCode
我的jQuery代码:
<script>
$(document).ready(function()
{
refresh();
});
function refresh()
{
$.post('getMessageDetails.php', function (json) {
$("#subject").html(json.subject);
$("#subject_id").html(json.subject_id);
$("#unique_code1").html(json.unique_code1);
$("#unique_code2").html(json.unique_code2);
$("#unique_code3").html(json.unique_code3);
});
window.setTimeout(refresh,30000);
}
</script>
然后我有newMessageCnt.php
<?php
<?php
header('Content-Type: application/json; charset=utf-8');
include('header_application.php');
$limit = 15;
if(!isset($_GET['page']))
$page = 1;
else
$page = $_GET['page'];
$from = (($page * $limit) - $limit);
$row = $obj_clean->getMessages($_SESSION['user_id'], $from, $limit);
if (count($row) > 0)
{
foreach ($row as $r)
{
$codeLength = strlen($r['unique_code']);
$codeLength = strlen($r['unique_code']);
$firstPartLength = $codeLength - 5;
$uniqueCode3 = substr($r['unique_code'], -2);
$uniqueCode2 = substr($r['unique_code'], -5, 3);
$uniqueCode1 = substr($r['unique_code'], 0, $firstPartLength);
$message_id = $r['id'];
$subject = $obj_clean->getMessageDetails($message_id);
$opened_once = $obj_clean->getOpenedOnce($message_id);
if ($opened_once >= 1)
{
$array['subject'] = $r['subject'];
$array['subject_id'] = $r['id'];
$array['unique_code1'] = $uniqueCode1;
$array['unique_code2'] = $uniqueCode2;
$array['unique_code3'] = $uniqueCode3;
}
}
}
echo json_encode($array);
exit();
&GT?; ?&GT;
我把这个.php称为其他地方,我只想要echo $obj_clean->getUnopenedMessagesCount($_SESSION['user_id']);
的价值
但是从我的messages.php我想要
echo '<td><a class="blue_link" href="'.ADDRESS.'view_message.php?id='.$r['id'].'">'.$r['subject'].'</a></td>';
echo '<td>'.$uniqueCode1.'<span class="pink_text">'.$uniqueCode2.'</span>'.$uniqueCode3.'</td>';
我不确定我是否正确行事,请一些建议吗?

$.post('ajax_call.php', function (json) {
$("#subject").html(json.subject);
$("#unique_code").html(json.unique_code);
});
// ajax_call.php
<?php
$array['subject']='bla-bla';
$array['unique_code']='1231312';
header('Content-Type: application/json; charset=utf-8');
echo json_encode($array);
exit();

最好是让PHP返回一个包含所需值的对象作为属性。这可以使用JSON发送回浏览器。您的客户端代码将此视为对象,可以提取属性并填充HTML。这会将您的演示文稿(VIEW)与您的数据(MODEL)分开。
