将javascript添加到Joomla网站的负责人 [英] Adding javascript to head of Joomla website
问题描述
我已经阅读了一些Joomla教程，我不了解Joomla的工作原理。我从来没有遇到过它的每一个方面都逃避我的事情。我不是要求免费乘车..只是去哪里或基本了解这是如何工作的。
I have gone through some Joomla tutorials and I am not understanding how Joomla works. I have never encountered something where every aspect of it evades me. I'm not asking for a free ride.. just where to go or a basic idea of how this works.
我只需将Panoramio javascript添加到< head>< / head> 部分joomla网站。在Word Press中，我只需下载header.php模板和代码。
I simply need to add a Panoramio javascript into the <head></head> section of a joomla website. In Word Press I simply download the header.php template and code away.
了解Joomla令人困惑。我知道不要直接粘贴到文章页面，所以我必须安装某种扩展或工具，甚至让它工作？
It's so confusing understanding Joomla. I do know not to paste directly into an "Article" page so do I have to install some sort of extension or tool to even get this to work?
我在模板中阅读编辑index.php，但我甚至找不到。我是唯一一个根本无法理解Joomla的人吗？即使是初学者文档似乎也假设我知道他们的系统。提前谢谢。
I read to edit the index.php in my templates but I can't even find that. Am I the only person that can't understand Joomla at all? Even the beginner documentation seems to assume I know their system. Thank you in advance.
推荐答案
请注意添加代码的文件。编辑模板文件夹中的index.php等核心文件可能不是最佳解决方案。如果有模板更新怎么办？该文件将被覆盖。所以请记住这一点。
Be careful about which files you add code to. Editing core files like the index.php in the templates folder might not be the best solution. What if there is a template update? The file will get overridden. So just bare that in mind.
在添加脚本之前，最好先获取当前模板的名称：
Before you add the script, it is good idea to get the name of current template:
$app = JFactory::getApplication();
$template = $app->getTemplate();
您可以使用以下内容导入 .js 提交< head> 标签：
You can use the following to import a .js file the <head> tags:
$doc = JFactory::getDocument(); //only include if not already included
$doc->addScript(JUri::root() . 'templates/' . $template . '/file.js');
或者您可以在那里添加Javascript然后如下：
or you can add the Javascript there and then like so:
$doc = JFactory::getDocument();
$js = "
//javascript goes here
";
$doc->addScriptDeclaration($js);
