我试图显示加载图像,直到 php 执行,查询在第二页上有效,但结果没有显示在第一页上,我知道我在这里遗漏了一些东西,有人可以帮我吗?我是 jquery 或 ajax 的新手。
主页.php
<html>
<head>
<!--Javascript-->
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
$('#loading_spinner').show();
var post_data = "items=" + items;
$.ajax({
url: 'list.php',
type: 'POST',
data: post_data,
dataType: 'html',
success: function(data) {
$('.my_update_panel').html(data);
},
error: function() {
alert("Something went wrong!");
}
});
$('#loading_spinner').hide();
</script>
<style>
#loading_spinner { display:none; }
</style>
</head>
<body>
<img id="loading_spinner" src="image/ajax-loader.gif">
<div class="my_update_panel">
<!--I am not sure what to put here, so the results can show here-->
</div>
list.php我测试了查询并打印了行。
<?php
include_once("models/config.php");
// if this page was not called by AJAX, die
if (!$_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest') die('Invalid request');
// get variable sent from client-side page
$my_variable = isset($_POST['items']) ? strip_tags($_POST['items']) :null;
//run some queries, printing some kind of result
$mydb = new mysqli("localhost", "root", "", "db");
$username = $_SESSION["userCakeUser"];
$stmt = $mydb->prepare("SELECT * FROM products where username = ?");
$stmt->bind_param('s', $username->username);
$stmt->execute();
// echo results
$max = $stmt->get_result();
while ($row = $max->fetch_assoc()) {
echo $row['title'];
echo $row['price'];
echo $row['condition'];
}
?>
