我应该将 Javascript 放在 HTML 文件的头部还是正文中？
[英]Should I Put Javascript in the Head or Body of an HTML File?
问题描述
I am making a search engine, and I have the code to redirect http to https when users access my page.
我正在制作一个搜索引擎，当用户访问我的页面时，我有代码将 http 重定向到 https。
Except I'm not sure if I should put it in the head or body section of my page.除了我不确定是否应该将它放在页面的头部或正文部分。
Here's what I've got:这是我所拥有的：
if(window.location.protocol != 'https:') {
location.href = location.href.replace("http://", "https://");
}
Also I would like to know if the code I have actually works if that's OK.另外我想知道我的代码是否真的有效，如果可以的话。

将它放在文档<head>中的<script>标签中，放在任何其他<script>标签之前，以便在下载页面的所有资源之前执行。

No matter where you put it will work but you would unnecessarily loading too many doms if you put the script tag later and also making the user wait slightly longer best is head.不管你把它放在哪里，它都可以工作，但是如果你稍后放置脚本标签，你会不必要地加载太多的dom，并且让用户等待的时间稍微长一点最好是头。
<head>
<script type="text/javascript">
if(window.location.protocol != 'https:') {
location.href = location.href.replace("http://", "https://");
}
</script>
</head>
