发布未选中的复选框(POST unchecked HTML checkboxes)

 我有一个加载复选框是默认检查。 我的用户可能会取消选中一些复选框（如果有），并留下其余的复选框。 有没有办法得到没有在窗体帖子中检查的复选框，而不是检查的复选框？ 

I've got a load of checkboxes that are checked by default. My users will probably uncheck a few (if any) of the checkboxes and leave the rest checked.  
Is there any way to make the form POST the checkboxes that are not checked, rather than the ones that are checked?

 说实话，JsHelper毫无用处。 我甚至没有理解它，我只是像往常一样在我的网站中包含JavaScript，但使用Cake的方法将其保留在框架内。  
 示例布局会在<head>包含jQuery，如下所示：  
 应用程序/浏览/设计/ default.thtml中  
<head>

<?php
    // Include jQuery
    echo $this->Html->script('jquery-1.8.2.min');

    // Want to send some glabal values to your scripts?
    $this->Js->set(array(
        'TEST' => 'Hello World',
        'ROOT' => $this->Html->url( '/', true)
    ));
    echo $this->Js->writeBuffer(array('onDomReady' => false));

    // Include any other scripts you've set
    echo $this->fetch('script');
?>

</head>
 
 然后在您的视图中，您可能希望包含该页面的特定脚本：  
 应用程序/视图/页/ test.ctp  
<?php echo $this->Html->script('test.js'); ?>
 
 您只需将所有JavaScript保存在外部脚本中：  
 应用程序/根目录/ JS / test.js  
$(document).ready(function() {

    /**
     * Alert the value we set in our layout.  All JS vars that have been
     * set are available in your JavaScript via the window.app object.
     */
    alert(window.app.TEST + ' sent from ' + window.app.ROOT);

});

JsHelper is pretty useless to be honest. I don't even bother with it properly, I just include JavaScript in my site as I would normally, but using Cake's methods to keep it within the framework. 
Example layout would have jQuery included in the <head> like this: 
app/View/Layouts/default.ctp 
<head>

<?php
    // Include jQuery
    echo $this->Html->script('jquery-1.8.2.min');

    // Want to send some glabal values to your scripts?
    $this->Js->set(array(
        'TEST' => 'Hello World',
        'ROOT' => $this->Html->url( '/', true)
    ));
    echo $this->Js->writeBuffer(array('onDomReady' => false));

    // Include any other scripts you've set
    echo $this->fetch('script');
?>

</head>
 
Then in your view, you might want to include a specific script for that page: 
app/View/Pages/test.ctp 
<?php echo $this->Html->script('test.js'); ?>
 
And you just keep all your JavaScript as usual in an external script: 
app/webroot/js/test.js 
$(document).ready(function() {

    /**
     * Alert the value we set in our layout.  All JS vars that have been
     * set are available in your JavaScript via the window.app object.
     */
    alert(window.app.TEST + ' sent from ' + window.app.ROOT);

});
