我试图创建一个电影网站。我几乎完成了所有事情。但这是一个问题。这是load_data.php文件的一部分，显示来自数据库的电影链接

$query_pag_num = "SELECT COUNT(*) AS count FROM videos";
$result_pag_num = mysql_query($query_pag_num);
$row = mysql_fetch_array($result_pag_num);
$count = $row['count'];
$no_of_paginations = ceil($count / $per_page);

这就是电影的显示位置

 <ul class="nav nav-tabs responsive" id="myTab">
    <li class="active"><a class="deco-none misc-class" href="#videos">All</a></li>
    <li><a href="#action">Action</a></li>
    <li><a href="#adventure">Adventure</a></li>
    <li><a href="#animation">Animation</a></li>
    <li><a href="#horror">Horror</a></li>
    <li><a href="#crime">Crime</a></li>
    <li><a href="#comedy">Comedy</a></li>
    <li><a href="#romance">Romance</a></li>
    <li><a href="#fantasy">Fantasy</a></li>
    <li><a href="#drama">Drama</a></li>
    <li><a href="#mystery">Mystery</a></li>
    <li><a class="deco-none" href="#thriller">Thriller</a></li>
    <li class="dropdown">
    <a data-toggle="dropdown" href="#">More <span class="caret"></span></a>
    <ul class="dropdown-menu pull-right" role="menu" aria-labelledby="dLabel">
    <li><a href="#war">War</a></li>
    <li><a href="#science-fiction">Science-fiction</a></li>
    <li><a href="#family">Family</a></li>
    </ul>
    </li>
    </ul>
  <div class="tab-content responsive">
    <div class="tab-pane fade in active" id="<?php $table='videos'; echo $table ?>">
<div class="row row1">
                <div style="margin-top:10px;"></div> 
    <div align="center" style="padding-bottom:80px" id="loading"></div>
    <div id="container">
        <div class="data"></div>
        <div class="pagination"></div>
    </div>

      </div>
    </div>
    <div class="tab-pane fade in" id="action">
<div class="row row1">
      </div>
    </div>

电影由jquery＆amp; ajax.now一切正常，因为我有包含所有电影的表格视频，我正在显示视频表格中的所有数据，但我想要做的是点击每个类别来显示该类别的电影。 这是完成工作的jquery＆amp; ajax 

<script type="text/javascript">
            $(document).ready(function(){
                function loading_show(){
                    $('#loading').html("<i class='fa fa-cog fa-spin fa-5x'>    
</i>").fadeIn('fast');
                }
                function loading_hide(){
                    $('#loading').fadeOut('fast');
                }                
                function loadData(page){
                    loading_show();                    
                    $.ajax
                    ({
                        type: "POST",
                        url: "load_data.php",
                        data: "page="+page,
                        success: function(msg)
                        {
                            $("#container").ajaxComplete(function(event, request,
settings)
                            {
                                loading_hide();
                                $("#container").html(msg);
                            });
                        }
                    });
                }
                loadData(1);  // For first time page load default results
                $('#container .pagination li.active').live('click',function(){
                    var page = $(this).attr('p');
                    loadData(page);
                });           
                $('#go_btn').live('click',function(){
                    var page = parseInt($('.goto').val());
                    var no_of_pages = parseInt($('.total').attr('a'));
                    if(page != 0 && page <= no_of_pages){
                        loadData(page);
                    }else{
                        alert('Enter a PAGE between 1 and '+no_of_pages);
                        $('.goto').val("").focus();
                        return false;
                    } 
                });
            });
        </script>

您可以在函数中传递第二个属性，如： - 

$('#container .pagination li.active').live('click',function(){
                    var page = $(this).attr('p');
                    loadData(page, category_id);
                });
