已弃用的Ajax或JQuery命令原因无返回结果

<script type="text/javascript">
        $(document).ready(function(){
            function loading_show(){
                $('#loading').html("<img src='images/loading.gif'/>").fadeIn('fast');
            }

                $('#loading').fadeOut('fast');
            }

上面是来自这里的分页教程的分页代码。我尝试使用jquery 1.9.1代替使用1.4的代码块。但似乎即使我把不赞成的。live改为。on，仍然没有结果呈现。我在这篇文章中找不到任何弃用的代码。然而，教程中的其他代码看起来也很完美。所以我认为一定是javascript &上面的Ajax代码
