将外部 JS 文件链接到 Prestashop [英] Link external JS file to Prestashop
问题描述
我正在 Prestashop 1.7 中创建一个自定义模块，我尝试了很多解决方案，但都没有解决我的问题.
I'm creating a custom module in Prestashop 1.7, and I've tried many solutions but nothing solved my problem.
我会在安装模块的网站的页眉或页脚中添加一个外部 JS 文件(并且仅在安装时添加).
I would add an external JS file to the header or footer of the website where the module is installed (and only when it's installed).
<script src="https://cdn.monurl.com/file.js"></script> // JS file to include
我尝试在 displayHeader 钩子中使用 addJS() 方法:
I tried to use the addJS() method in the displayHeader hook:
public function hookDisplayHeader($params)
{
if (!$this->active)
return;
$this->context->controller->addJS('https://cdn.monurl.com/file.js');
}
public function install()
{
return parent::install() && $this->registerHook('displayHeader');
}
我做了很多测试，调用了hookDisplayHeader()函数，但是我的JS文件没有出现在我页面的<head>.
I made a lot of tests, and the hookDisplayHeader() function is called, but my JS file doesn't appear in the <head> of my page.
Prestashop 的文档有限，但经过多次研究，我认为我只能将 addJS() 方法与内部 JS 文件一起使用.我说得对吗?
The Prestashop documentation is limited, but after many researches, I think I can only use the addJS() method with internal JS files. Am I right?
如何将外部 JS 文件添加到我的页眉(或 </body> 之前的页脚)?
How should I do to add an external JS file to my header (or footer before </body>)?
推荐答案
addJS() 函数在 PrestaShop 1.7 中已弃用.您现在必须使用 registerJavascript().
addJS() function is deprecated in PrestaShop 1.7. You now have to use registerJavascript().
$this->context->controller->registerJavascript(
'monurl', // Unique ID
'https://cdn.monurl.com/file.js', // JS path
array('server' => 'remote', 'position' => 'bottom', 'priority' => 150) // Arguments
);
这里你不能忘记的重要参数是 'server' =>'remote' 加载外部 JS 文件.
The important argument you must not forget here is 'server' => 'remote' to load an external JS file.
您可以在文档中找到有关此功能的更多信息:https://developers.prestashop.com/themes/assets/index.html
You can find more information about this function here in the doc: https://developers.prestashop.com/themes/assets/index.html
再想想你的代码，你不用放:
Another think about your code, you do not have to put:
if (!$this->active)
return;
如果模块被禁用，则不会调用整个钩子.
The entire hook will not be called if the module is disabled.
