在“bottom”处加载CakePHP布局中的Javascript文件 [英] Load Javascript files in CakePHP Layout at "bottom"

问题描述

目前，我有一个大的CakePHP应用程序的布局和很多的意见。在布局中，我加载了大多数视图所需的头文件中的Javascript文件。在视图中，我自己，我加载额外的Javascript文件（例如，加载只需要那里的库文件），或者我添加一些Javascript代码，只在脚本标记中与此视图相关，例如，如果我需要一个点击处理程序。

Currently, I have a big CakePHP application with a layout and a lot of views. In the layout, I load Javascript files in the head which are needed by most views. In the views themself, I either load additional Javascript files (e.g., load a library file that is only needed there), or I add some Javascript code that is only relevant for this view in a script tag, for example if I need a click handler.

因为一个已知的事实，即在HTML头部加载Javascript文件阻止加载页面，我想把它们放在底部，然后关闭body标签。但是如果我这样做，我的视图中加载内容的Javascript打断，因为它不知道我加载的Javascript文件。我理解加载视图中的Javascript代码在加载文件之前执行。但是我该如何防止呢？

Since it is a known fact that loading Javascript files in the HTML head blocks loading the page, I wanted to put them at the bottom before closing the body Tag. But if I do so, the Javascript in my views that load the content breaks because it does not know about my loaded Javascript files. I understand that the Javascript code in the loaded views is executed before my files are loaded. But how can I prevent that?

我目前正在使用布局（和其他地方）中的HTML助手加载我的JS文件，如下所示：

I'm currently using the HTML Helper in the Layout (and everywhere else) to load my JS files like this:

<?php echo $this->Html->script('//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js'); ?>

我使用JS Helper在页面末尾输出JS。

And I use the JS Helper to "output" JS at the end of the page with

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

有没有办法我可以在视图中追加我的JS代码，调用writeBuffer？这能帮助我吗？

Is there a way I can append my JS code in the views, so that it is executed when I call writeBuffer? Can that help me out?

推荐答案

这是我在我看来：

echo $this->Html->script('filename', array('inline' => false));

这是我在我的布局底部做的：

And this is what I do at the bottom of my layout:

echo $this->fetch('script');
