在Yii框架上使用ajaxButton / ajaxSubmitButton阻止加载jQuery资产 [英] Prevent loading of jQuery assets with ajaxButton/ajaxSubmitButton on Yii framework

问题描述

我的布局上有jQuery加载资产，我想使用 CHtml :: ajaxButton / ajaxSubmitButton 。
但是当我在运行时使用它与另一个渲染时，它再次加载jQuery资产并出错。
如何阻止脚本加载？

I have jQuery load asset on my layout and I want to use CHtml::ajaxButton/ajaxSubmitButton. But when I'm using it with another render on runtime it's loading jQuery assets again and makes an error. How to prevent the script from loading?

<?php echo CHtml::ajaxSubmitButton( 'Submit',
                                        CHtml::normalizeUrl(array('site/AjaxRequest/30')),
                                        array(
                                        'error'=>'js:function(){
                                            alert(\'error\');
                                        }',
                                        'beforeSend'=>'js:function(){
                                            alert(\'beforeSend\');
                                        }',
                                        'success'=>'js:function(data){
                                            alert(\'data from server: \'+data);
                                        }',
                                        'complete'=>'js:function(){
                                            alert(\'complete\');
                                        }',
                                        //'update'=>'#response',
                                        )
                                    );
    ?>

推荐答案

这也是一个非常讨厌的问题IMO。我解决的方法是创建一个CClientScript派生类，并将其用作clientScript组件（您可以覆盖配置文件中的类类型）：

This is a pretty annoying issue IMO as well. The way I solved is to create a derived class of CClientScript and use that as the clientScript component (you can override the class type in your config file):

'clientScript' => array
(
    'class'                       => 'MyClientScript',
),

我的类重写了registerCoreScript函数，该函数用于注册jii和Yii包含的其他基本脚本。
我在那里做的几乎就是添加ajax的检查，如果是的话，不将它传递给父类。
它看起来像这样：

My class overrides the "registerCoreScript" function, which is used for registering jQuery and other basic scripts that Yii includes. Pretty much what I do in there is add a check for ajax and not pass it on to the parent class if it is. It looks something like this:

public function registerCoreScript($sName)
{
   if (Yii::app()->request->isAjaxRequest)
      return $this;

   return parent::registerCoreScript($sName);
}

这可以防止在ajax期间加载任何核心脚本（并再次添加资产）调用。

This prevents any core script being loaded (and adding assets again) during an ajax call.

您也可以对其他函数执行相同的操作（例如registerScriptFile）

You can do the same for other functions in there too (eg registerScriptFile)
