改造thinkphp 的 Page类,使其支持ajax方式
效果:
改造thinkphp 的 Page类,使其支持ajax方式
说明:thinkphp版本:3.2.1
步骤:
1、打开Page.class.php(路径:ThinkPHP/Library/Think)
找到第48行:
 empty($_GET[$this->p]) ? 1 : intval($_GET[$this->p]);  改为:
 empty(I($this->p)) ? 1 : intval(I($this->p));
实际是改为用内置的 I 函数读取传递进来的P参数,这样并不会影响原有的功能。

2、ajax方式的调用:
即前台html页面
<div>此处用来显示分页内容</div> <br><br> javascript:    function jzry(p) {<br>         var request = $.ajax({<br>             url: "__MODULE__/Home/jzrh",  //用ajax加载分页数据<br>             type: "POST",<br>             async: false,<br>             data:{p:p},<br>             beforeSend: function(xhr) {<br>                 $('#message').html("正在加载数据,请稍候。");<br>             }<br>         });<br>         request.done(function(msg) {<br>             if (msg.bj == 'ok') {<br>                 $('#rs').html(msg.page);    //显示分页<br>                 $("#rs a").removeAttr("href");   //删除原来的连接地址方式,<br>                 <br>                 //改用ajax按键事件<br>                 $(".num,.end,.first").on("click", function(){<br>                     jzry( $(this).text() );<br>                 });<br>                 $(".next").on("click", function(){<br>                     jzry( parseInt($(".current").text())+1);<br>                 });<br>                 $(".prev").on("click", function(){<br>                     jzry( parseInt($(".current").text())-1);<br>                 });<br>         }});<br>         request.fail(function(jqXHR, textStatus) {<br>             $('#message').html("错误: " + textStatus);<br>         });<br>     } 样式: <style><br /> #rs a { color:#333;display:block; padding:0px 6px;<br /> font-weight:bold;float:left;border:1px solid #5d9cdf;<br /> height:20px; line-height:20px; margin:0px 2px;}<br /> .current { background:#a9d2ff; display:block; padding:0px 6px;<br /> font-weight:bold;;float:left}<br /> .clear{clear:both}<br /> </style>
3、后台使用和原来的一样 <br>         $user = M("user"); <br>         $User = $user->page($_POST['p'].',20')->order('id')->select();<br>         if ($User > 0) {<br>             $val['bj'] = 'ok';<br>             $count=$user->count();<br>             $Page=new \Think\Page($count,20);<br>             $val['page']=$Page->show();<br>             $this->ajaxReturn($val);                      //ajax方式返回<br>         }
