我正在尝试每秒更新部分 HTML 并将数据从数据库中提取到该 Div 中,但代码不起作用。:(请帮忙。第一部分代码是调用更新函数的html页面,并在check_status.php上进行ajax调用,check_status.php从数据库中的php文件中获取数据
<html>
<head>
<title>Reloading testing</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
var statusIntervalId = window.setInterval(update, 1000);
function update() {
$.ajax({
url: 'check_status.php',
dataType: 'text',
success: function(data) {
if (parseInt(data) == 0) {
$("#status").css({ color: "red" }).text("offline");
} else {
$("#status").css({ color: "green" }).text("online");
}
}
}
}
</script>
</head>
<body>
<h1>Refresh part of the page</h1>
<div id="status">
</div>
</body>
</html>
This is check_status.php

<?php
$con = mysql_connect("localhost", "root", "");
mysql_select_db("manchesterunited", $con);
$row = mysql_fetch_array(mysql_query("SELECT * FROM players LIMIT 1"));
mysql_close($con);
echo $row[0]; ?>
</body>
</html>
