基於ajax實現點擊載入更多無重新整理載入到本頁_AJAX相關

先給大家展示效果圖：

效果示範

本例是分頁的另外一種顯示方式,並不是隱藏未顯示的內容

資料庫結構與《ajax 翻頁》是一樣的

JavaScript 代碼

<script type="text/javascript"> $(document).ready(function() {   var track_click = ; //track user click on "load more" button, righ now it is click   var total_pages = <?php echo $total_pages; ?>;   $('#results').load("fetch_pages.php", {'page':track_click}, function() {track_click++;}); //initial data to load   $(".load_more").click(function (e) { //user clicks on button     $(this).hide(); //hide load more button on click     $('.animation_image').show(); //show loading image     if(track_click <= total_pages) //make sure user clicks are still less than total pages     {       //post page number and load returned data into result element       $.post('fetch_pages.php',{'page': track_click}, function(data) {         $(".load_more").show(); //bring back load more button         $("#results").append(data); //append data received from server         //scroll page to button element         $("html, body").animate({scrollTop: $("#load_more_button").offset().top}, );         //hide loading image         $('.animation_image').hide(); //hide loading image once data is received         track_click++; //user click increment on load button       }).fail(function(xhr, ajaxOptions, thrownError) {          alert(thrownError); //alert any HTTP error         $(".load_more").show(); //bring back load more button         $('.animation_image').hide(); //hide loading image once data is received       });       if(track_click >= total_pages-)       {         //reached end of the page yet? disable load button         $(".load_more").attr("disabled", "disabled");       }      }     }); }); </script>

XML/HTML代碼

<div id="results"></div> <div align="center"> <button class="load_more" id="load_more_button">load More</button> <div class="animation_image" style="display:none;"><img src="ajax-loader.gif"> Loading...</div> </div> 

 fetch_pages.php

 php代碼

<?php include("conn.php"); $item_per_page = 3; //sanitize post value $page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);  //throw HTTP error if page number is not valid if(!is_numeric($page_number)){   header('HTTP/1.1 500 Invalid page number!');   exit(); }  //get current starting point of records $position = ($page_number * $item_per_page);  //Limit our results within a specified range.  $results = mysql_query("SELECT * FROM content ORDER BY id DESC LIMIT $position, $item_per_page");  //output results from database echo '<ul class="page_result">'; while($row = mysql_fetch_array($results)) {   echo '<li id="item_'.$row["id"].'"><span class="page_name">'.$row["id"].') '.$row["name"].'</span><span class="page_message">'.$row["message"].'</span></li>'; } echo '</ul>'; ?>
