我想在列表页面中创建添加/编辑/删除和活动/取消活动（使用 ajax）。在这里，我已经上传了演示http://mehul.pw/cp/categories/index 现在分页工作正常。但是当我更改状态然后使用分页时，它就不起作用了。我正在尝试从 3 小时开始解决这个问题，我在我的代码下面提到了

控制器代码如下： 

    public $helpers = array('Js' => array('Prototype'));
    public $components = array();

    public function beforeFilter()
    {
        parent::beforeFilter();
    }
    public $paginate = array(
        'limit' => 1,
        'order' => array(
            'Category.category_id' => 'asc'
        )
    );
    public function index()
    {

        $data = $this->paginate('Category');
    $this->set('categories',$data);

    }
 public function update($field,$value,$id = null,$pageno,$sortkey,$sortdir)
    {

        if (!$id) {
                $this->Session->setFlash(__('Invalid id for Event', true));
                $this->redirect(array('action'=>'index'));
        }
        $this->Category->id = $id;
        $this->request->data['Category'][$field] = $value;
        if($this->Category->save($this->request->data))
    {
           $this->redirect(array('action'=>'index', 'page' => $pageno, 'sort' => $sortkey, 'direction' => $sortdir));
        }else{
        $this->redirect(array('action'=>'index', 'page' => $pageno, 'sort' => $sortkey, 'direction' => $sortdir));
    }
    }
}

现在在我的活动/非活动链接的索引文件中，我使用了这个

<?php
            if($post['Category']['is_active'] == 'Y'){
                echo $this->Js->link( 'Active', array('action' => 'update','is_active','N', $post['Category']['category_id'],$this->paginator->current(),$this->paginator->sortKey(),$this->paginator->sortDir()), array('async' => false,'update' => 'content'));    
            }else{
                echo $this->Js->link( 'DeActive', array('action' => 'update','is_active','Y', $post['Category']['category_id'],$this->paginator->current(),$this->paginator->sortKey(),$this->paginator->sortDir()), array('async' => false,'update' => 'content'));    
            }

            ?>

你能告诉我如何解决这个问题吗？提前致谢。

在这里，我也尝试使用 ajax 助手，但是这里的 dame 问题我提到了填充视图代码

<?php // pr($this->Paginator->options);
$this->Paginator->options(array(
    'update' => '#content',
    'evalScripts' => true,
    'before' => $this->Js->get('#busy-indicator')->effect('fadeIn', array('buffer' => false)),
    'complete' => $this->Js->get('#busy-indicator')->effect('fadeOut', array('buffer' => false)),
));
?>

<h1>Categories List</h1>
<?php //echo $this->Html->link('Add Post',array('controller' => 'categories', 'action' => 'add')); ?>
<?php echo $this->html->link('Add Category',array('controller'=>'categories','action'=>'add'),array("escape" => false,'class'=>'stdbtn btn_orange', "title" => "Add Category", "onclick" => "Modalbox.show(this.href, {title: this.title, width: 700}); return false;")); ?>

<table>
    <?php

    //echo $this->Html->tableHeaders(array('Date','Title','Active'),array('class' => 'status'),array('class' => 'product_table'));?>
    <tr>

        <th><?php echo $this->Paginator->sort('category_id', '<em>Category Id</em>', array('escape' => false)); ?></th>
        <th><?php echo $this->Paginator->sort('category_name', '<em>Name</em>', array('escape' => false)); ?></th>
        <th>Description</th>
        <th>Status</th>
        <th>Action</th>        
    </tr>
    <!-- Here is where we loop through our $posts array, printing out post info -->

    <?php  foreach ($categories as $post): ?>
    <tr>
         <td><?php echo $post['Category']['category_id']; ?></td>
        <td>
            <?php echo $this->Html->link($post['Category']['category_name'],array('controller' => 'categories', 'action' => 'view', $post['Category']['category_id'])); ?>
        </td>
        <td><?php echo $post['Category']['description']; ?></td>
        <td>

            <?php
            if($post['Category']['is_active'] == 'Y'){
                echo $this->Js->link( 'Active', array('action' => 'update','is_active','N', $post['Category']['category_id'],$this->paginator->current(),$this->paginator->sortKey(),$this->paginator->sortDir()), array('async' => false,'update' => 'content'));    
            }else{
                echo $this->Js->link( 'DeActive', array('action' => 'update','is_active','Y', $post['Category']['category_id'],$this->paginator->current(),$this->paginator->sortKey(),$this->paginator->sortDir()), array('async' => false,'update' => 'content'));    
            }

            ?>
        </td>
        <td>
            <?php echo $this->Form->postLink(
                'Delete',
                array('action' => 'delete', $post['Category']['category_id']),
                array('confirm' => 'Are you sure?'));
            ?>
            <?php echo $this->Html->link('Edit', array('action' => 'edit', $post['Category']['category_id'])); ?>
        </td>
    </tr>
    <?php endforeach; ?>
    <tr>
        <td colspan="4" align="right">
         <?php

        echo $this->Paginator->first('< first  ');
        echo $this->Paginator->prev(' << ' . __('previous  '), array(), null, array('class' => 'prev disabled'));
        echo $this->Paginator->numbers();    
        echo $this->Paginator->next( __('  next').' >> ' , array(), null, array('class' => 'next disabled'));  
        echo $this->Paginator->last('  Last > ');  


        //echo $this->Paginator->counter('Page {:page} of {:pages}, showing {:current} records out of{:count} total, starting on record {:start}, ending on {:end}');
        ?>

        <?php echo $this->Html->image('indicator.gif', array('id' => 'busy-indicator')); ?>
        </td>
    </tr>
    <?php unset($post);

    ?>
</table>

<?php  echo $this->Js->writeBuffer(); ?>

<?php echo $this->Js->writeBuffer(); ?>关闭前添加<div id='content'>

我认为，如果您触发 ajax 调用，内容正在更新，但分页链接和分页链接的相关脚本并未在此处更新，我认为您的分页链接不会在此处更新，

IE

$("link-907864750").observe("click", function (event) {event.stop();
var jsRequest = new Ajax.Updater("content", "/cp/categories/index/sort:category_name/direction:asc", {evalScripts:true, onComplete:function (transport) {$("busy-indicator").fade({buffer:false});}, onCreate:function (transport) {$("busy-indicator").appear({buffer:false});}});});

$("link-907864750")是您稍后单击“停用”或“激活”时第一次拥有的链接，这不会更新脚本/甚至不会为那里的分页链接生成脚本。

注意： $("#link-907864750")这里是一个示例，cake 将为分页链接生成随机 id。
