向CakePHP中的每个视图添加特定于页面的Javascript [英] Adding page-specific Javascript to each view in CakePHP
问题描述
为了保持我的脚本可维护性，我将把每个文件移动到自己的文件中，由控制器和操作组织：
In an attempt to keep my scripts maintainable, I'm going to move each into their own file, organised by controller and action:
// scripts which only apply to /views/posts/add.ctp
/app/webroot/js/page/posts/add.js
// scripts which only apply to /view/users/index.ctp
/app/webroot/js/page/users/index.js
这很酷，但是我想让这些由控制器自动添加，因为它显然知道控制器和操作的名称。
That's all cool, however I'd like for these to be automatically added by the Controller, since it obviously knows the name of both the controller and action.
我认为最好的地方是 AppController :: beforeRender（）。 （yes？）
I figure the best place for this is in AppController::beforeRender(). (yes?)
唯一的问题是我不知道如何将它添加到 $ scripts_for_layout 变量。我认为得到一个引用 javascript 帮助器对象将工作，但我不能从控制器中找到它！
The only problem is that I don't know how to actually add this into the $scripts_for_layout variable. I thought that getting a reference to the javascript helper object would work, but I can't find it from the controller!
class AppController extends Controller {
var $helpers = array("javascript", "html", "form");
function beforeRender() {
// ???
}
}
推荐答案
容易在 default.ctp 布局文件中进行：
Very easy to do in your default.ctp layout file:
自动包含 .css 每个控制器和/或控制器/操作的文件（因为我有这个，容易适应 .js 文件）：
An example to automatically include .css files per controller and/or controller/action (because I had this lying around, easily adaptable to .js files):
<head>
...
<?php
if (is_file(WWW_ROOT . 'css' . DS . $this->params['controller'] . '.css')) {
echo $html->css($this->params['controller']);
}
if (is_file(WWW_ROOT . 'css' . DS . $this->params['controller'] . DS . $this->params['action'] . '.css')) {
echo $html->css($this->params['controller'] . '/' . $this->params['action']);
}
?>
...
</head>
