PHP+jQuery+Ajax实现分页效果 jPaginate插件的应用_PHP
jPaginate是基于jQuery的动感滚动分页插件,它的表现形式是像分页的按钮一样,非常有意思的是这些按钮却可以滚动,可以通过单击或鼠标滑向点两侧的小箭头来控制按钮的前后滚动。
调用jPaginate插件的方法很简单:
$(elementID).paginate()
属性设置
可喜的是,jPaginate提供了很多属性配置,您可以轻易的定制想要的分页效果。
设置方法如:
$(elementID).paginate({ count:80, start:1, ... })
count: 数字,总记录数。
start: 数字,开始显示的页数,如:3表示从第3页开始。
display: 数字,分页条显示的页数,如:5表示一次显示5个页码数。
border: 是否显示页码的边框。(true/false)
border_color: 设置边框的颜色,如"#d3d3d3"。
text_color: 设置页码的颜色,如"#68ba64"。
background_color: 设置页码的背景色,如"#f7f7f7"。
border_hover_color: 设置鼠标滑向页码时页码边框的颜色。
text_hover_color: 设置鼠标滑向页码时页码的颜色。
background_hover_color: 设置鼠标滑向页码时页码背景的颜色。
images: 是否显示页码导航箭头(方向箭头)(true/false)
mouse: 设置为'press'时,当鼠标滑向导航箭头时,页码随之滚动;设置为'slide'时,鼠标单击一次导航箭头页码滚动一次。
onChange: 当单击页码时,回调函数.
实例应用:PHP+jQuery实现Ajax分页效果
首先准备index.php,该页面用来分页展示一个博客文章列表。
1、引用JS:
<script type="text/javascript" src="js/jquery.js"></script> <script type="text/javascript" src="js/jquery.paginate.js"></script> <script type="text/javascript"> $(function(){ $("#demo").paginate({ count : <?php echo $page;?>, start : 1, display : 5, border : true, border_color : '#BEF8B8', text_color : '#79B5E3', background_color : '#E3F2E1', border_hover_color : '#68BA64', text_hover_color : '#2573AF', background_hover_color : '#CAE6C6', images : false, mouse : 'press', onChange : function(page){ $("#pagetxt").load("article.php?id="+page); } }); }); </script>
注意,关于插件的属性设置,上文已详细介绍,属性count通过PHP计算出总页数$page,该参数由article.php得出。还要说明的是属性onChange:当点击页码时,调用函数,该函数实现了异步提交页码参数给article.php来处理,article.php通过读取数据库里的表书籍,并把得到的文章列表结果而返回页面,这就是Ajax。当然我这里只是做简单的演示,如果需要更多异步效果,可以参照jQuery使用文档。
2、引用CSS:
jPaginate官方提供了导航条样式,你也可以自己写个非常酷的样式。
<link rel="stylesheet" type="text/css" href="style.css" />
3、index.php初始页面。
必须要显示一个初始的文章列表,代码如下
<div class="demo"> <h4 id="Demo-Php-jQuery实现AJAX-分页效果">Demo 3: Php+jQuery实现AJAX 分页效果</h4> <div id="pagetxt"> </div> <div id="demo"></div> </div>
在ID为pagetxt的DIV内加入PHP代码:
$query=$db->select("article","id,title,pubdate","cata=1 order by id desc limit 0,5"); while($row=$db->fetch_array($query)){ $pubdate=date("Y-m-d",$row[pubdate]); echo "<p><span>$pubdate</span><a href='view-blog-".$row[id].".html' target='_blank'> ".$row[title]."</a></p>";
4、article.php代码。
该代码用来获取index.php提交过来的页码,查询数据库,并将输出结果。代码如下:
include_once("common.php"); //连接数据库专用文件 $id=$_GET['id']; //获取页码 $result = $db->select("article", "id", "cata=1"); $total = $db->db_num_rows($result); //总记录数 $pagesize=5; //每页显示数 $page=ceil($total/$pagesize); //总页数 if(isset($id)){ $startPage=($id-1)*$pagesize; $query=$db->select("article","id,title,pubdate","cata=1 order by id desc limit $startPage, $pagesize"); while($row=$db->fetch_array($query)){ $pubdate=date("Y-m-d",$row[pubdate]); echo "<p><span>$pubdate</span><a href='view-blog-".$row[id].".html' target='_blank'> ".$row[title]."</a></p>"; //输出文章列表 } }
以上介绍了PHP+jQuery实现Ajax分页效果中jPaginate插件的应用,希望对大家的学习有所帮助。

How to use PUT request method in jQuery? In jQuery, the method of sending a PUT request is similar to sending other types of requests, but you need to pay attention to some details and parameter settings. PUT requests are typically used to update resources, such as updating data in a database or updating files on the server. The following is a specific code example using the PUT request method in jQuery. First, make sure you include the jQuery library file, then you can send a PUT request via: $.ajax({u

Using Ajax to obtain variables from PHP methods is a common scenario in web development. Through Ajax, the page can be dynamically obtained without refreshing the data. In this article, we will introduce how to use Ajax to get variables from PHP methods, and provide specific code examples. First, we need to write a PHP file to handle the Ajax request and return the required variables. Here is sample code for a simple PHP file getData.php:

Title: jQuery Tips: Quickly modify the text of all a tags on the page In web development, we often need to modify and operate elements on the page. When using jQuery, sometimes you need to modify the text content of all a tags in the page at once, which can save time and energy. The following will introduce how to use jQuery to quickly modify the text of all a tags on the page, and give specific code examples. First, we need to introduce the jQuery library file and ensure that the following code is introduced into the page: <

Title: Use jQuery to modify the text content of all a tags. jQuery is a popular JavaScript library that is widely used to handle DOM operations. In web development, we often encounter the need to modify the text content of the link tag (a tag) on the page. This article will explain how to use jQuery to achieve this goal, and provide specific code examples. First, we need to introduce the jQuery library into the page. Add the following code in the HTML file:

Build an autocomplete suggestion engine using PHP and Ajax: Server-side script: handles Ajax requests and returns suggestions (autocomplete.php). Client script: Send Ajax request and display suggestions (autocomplete.js). Practical case: Include script in HTML page and specify search-input element identifier.

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

How to tell if a jQuery element has a specific attribute? When using jQuery to operate DOM elements, you often encounter situations where you need to determine whether an element has a specific attribute. In this case, we can easily implement this function with the help of the methods provided by jQuery. The following will introduce two commonly used methods to determine whether a jQuery element has specific attributes, and attach specific code examples. Method 1: Use the attr() method and typeof operator // to determine whether the element has a specific attribute

jQuery is a popular JavaScript library that is widely used to handle DOM manipulation and event handling in web pages. In jQuery, the eq() method is used to select elements at a specified index position. The specific usage and application scenarios are as follows. In jQuery, the eq() method selects the element at a specified index position. Index positions start counting from 0, i.e. the index of the first element is 0, the index of the second element is 1, and so on. The syntax of the eq() method is as follows: $("s
