大家好我有一个(可能)简单的问题,但我只是不明白为什么它不工作。这个jQuery Selector的问题
下面的代码应该是相当容易做到:
<?php
require('../db.php');
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>Website Checker</title>
<link href="style.css" rel="stylesheet" type="text/css" media="screen" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.simpletip-1.3.1.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#check').click(function(){
$('.http-status').html('<img src="images/spinner.gif"/>').fadeOut('slow').fadeIn('slow');
$('#site-list li.websites').each(function()
{
//var newurl = $(this).find('span.url a').attr('href');
var newurl = $(this).find('span.url').html();
$.ajax(
{
type: "POST",
url: "process.php",
data: ({"a":newurl}),
cache: false,
success: function(message)
{
$(this).find('span.http-status').html(message);
} //End AJAX return
}); //End AJAX call
}); //End li each
}); //End Check
$('#check').click();
});
</script>
<ul id="site-list" class="list">
<li class="title">
<span class="id"></span>
<span class="name">Title</span>
<span class="url">URL</span>
<span class="status">HTTP Status</span>
</li>
<?php
// some PHP to fetch all the gig entries from the shows table
$sql = "SELECT * FROM `check`";
$query = mysql_query($sql) or die(mysql_error());
// a loop to place all the values in the appropriate table cells
while ($row = mysql_fetch_array($query)){
//begin the loop...
$id=$row['id'];
$name=$row['name'];
$url=$row['url'];
?>
<li class="websites">
<span class="id"><?php echo $id; ?></span>
<span class="name"><?php echo $name; ?></span>
<span class="url"><?php echo $url; ?></span>
<span class="status http-status"></span>
</li>
<?php
}
?>
</ul>
<br />
<a href="#" id="check" class="button">Check Now</a>
这基本上是从一个数据库拉网站数据并将其呈现给用户,并且我所试图做的是当你单击该按钮每个站点的http代码进行检查和显示(也可以在页面首次加载时运行)
这似乎工作正常 - 正确的数据发送和接收,但之后,微调框仍然存在!

process.php(如果它帮助):
<?php
require('../db.php');
$url= NULL;
if(isset($_POST['a'])) { $url = mysql_real_escape_string($_POST['a']); }
function Visit($url)
{
$agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";$ch=curl_init();
curl_setopt ($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch,CURLOPT_VERBOSE,false);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
$page=curl_exec($ch);
//echo curl_error($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if($httpcode>=200 && $httpcode<300)
{
echo '<span class="up">'.$httpcode.'<span class="icon"><img src="images/info.png" alt="website is up"/></span></span>'; exit;
}
else
{
$httpcode=404;
$date = date("l, j \of F Y \@ H:i");
$to = "[email protected]";
$subject = "Urgent: $url is down";
$message = "Hello,\n\nIt appears that on our latest check of $url on $date that the site was down.\n\nRegards,\nWeb Checker";
$headers = 'From: [email protected]' . "\r\n" .
'Reply-To: [email protected]' . "\r\n";
mail($to, $subject, $message, $headers);
echo '<span class="down">'.$httpcode.'<span class="icon"><img src="images/info.png" alt="website is down"/></span></span>'; exit;
}
}
if(!empty($url)){ Visit($url); exit; }
?>
感谢,跨度是现在AJAX调用后清空,但响应消息仍未显示:/ – martincarlin87
跨度不应该被清空,多数民众赞成在你把你的数据,它看起来像...在填充跨度之前,需要清空父容器$('。http-status'),这将移除微调器 – NateB
