This is the problem我创建了一个页面，它获取变量并处理它并从数据库中获取数据。 获取的数据由分页函数文件分页。 我想使用图像加载器，当我点击第2页时，加载图像应该出现，直到数据显示，一旦数据显示，加载图像应该消失。
以下是我的档案......
<?php
session_start();
if (isset($_GET["topic_name"]))
{
$_SESSION['topic_name']=$_GET["topic_name"];
$topicget = $_SESSION['topic_name'];
}
else
{
$topicget = 'Age';
}
//get the function
include_once('dbconnect.php');
include_once ('function.php');
$page = (int) (!isset($_GET["page"]) ? 1 : $_GET["page"]);
$limit = 15;
$startpoint = ($page * $limit) - $limit;
//to make pagination
$statement = "`topic`,`author`,`quote` WHERE ( quote.topics REGEXP '[[:<:]]{$topicget}[[:>:]]' and topic.topic_en= '{$topicget}')and quote.author_id=author.id";
$query = mysqli_query($con,"SELECT * FROM {$statement} LIMIT {$startpoint} , {$limit}");
if($query === FALSE) {
die(mysqli_error($con)); // TODO: better error handling
}
?>

添加一个gif，给它一个id ='imgloader'。
<script>
$(document).ready({
$("#imgloader").hide(); //will hide the gif
$("#masonry").click(function(){
$("#imgloader").show(); //when pagination is clicked, loader will show
$("#masonry").hide();// to hide your mess data
});
});
</script>
修改1
<script>
$(document).ready(function (){
$("#imgloader").hide(); //will hide the gif
$("#masonry").ajaxStart(function(){
$("#imgloader").show(); //loader will show
$("#masonry").hide();// to hide your mess data
});
$("#masonry").ajaxStop(function () {
$('#imgloader').hide();// loader will hide
$("#masonry").show();// to show your mess data
});
});
</script>
