事件功能及说明

Sr.No	Event Function & Description
1	Helper::beforeRender(Event $event,$viewFile) The beforeRender method is called after the controller’s beforeRender method but before the controller renders view and layout. This receives the file being rendered as an argument.
2	Helper::beforeRenderFile(Event $event, $viewFile) This method is called before each view file is rendered. This includes elements, views, parent views and layouts.
3	Helper::afterRenderFile(Event $event, $viewFile, $content) This method is called after each View file is rendered. This includes elements, views, parent views and layouts. A callback can modify and return $content to change how the rendered content will be displayed in the browser.
4	Helper::afterRender(Event $event, $viewFile) This method is called after the view has been rendered, but before the layout rendering has started.
5	Helper::beforeLayout(Event $event, $layoutFile) This method is called before the layout rendering starts. This receives the layout filename as an argument.
6	Helper::afterLayout(Event $event, $layoutFile) This method is called after the layout rendering is complete. This receives the layout filename as an argument.

Helper::beforeRender(Event $event,$viewFile) beforeRender 方法在控制器的 beforeRender 方法之后、控制器渲染 view 和 layout 之前调用。它接收作为参数呈现的文件。

Helper::beforeRenderFile(Event $event, $viewFile) 该方法在每个视图文件渲染之前被调用。这包括元素、视图、父视图和布局。

3

Helper::afterRenderFile(事件$event, $viewFile, $content) 每个View文件渲染后都会调用该方法。这包括元素、视图、父视图和布局。回调可以修改并返回 $content 以更改渲染内容在浏览器中的显示方式。

4

Helper::afterRender(Event $event, $viewFile) 此方法在视图渲染之后、布局渲染开始之前调用。

5

Helper::beforeLayout(Event $event, $layoutFile) 该方法在布局渲染开始之前调用。它接收布局文件名作为参数。
