在HTML中设置新预渲染或预取的正确方法是什么？ [英] What's the right method to set a new prerender or prefetch in HTML?
问题描述
<！DOCTYPE html>
< meta charset =utf-8>
< title> HTML文件< / title>
< link rel =prefetchhref =https://www.apple.com/>
< link rel =prerenderhref =https://www.apple.com/>
< script>
document.addEventListener（'click'，function（）{
//在Chrome上预呈现https://www.apple.com/ipad
// ...
//在Firefox上预取https://www.apple.com/ipad
// ...
}，false）;
< / script>
当页面打开时， https://www.apple.com/ 是在不同的浏览器上预渲染和预取的。当单击文档时，我希望预渲染和预取另一个页面， https://www.apple.com/ipad 。
看来我们有两种方法可供选择。我们可以替换当前2 link 元素中的URL。或者我们可以在 head 元素中插入2个新的 link 元素。
什么是在HTML中设置新预渲染的正确方法？
在HTML中设置新预取的正确方法是什么？
我尝试从 link 元素的URL > https://www.apple.com/ 以 https://www.apple.com / ipad 。我开启了Chrome的任务管理器，发现 https://www.apple.com/ipad wasn'预先准备好了唯一的分段页面仍然是 https://www.apple.com/ 。所以看起来这种方法是行不通的？
< link rel =" prefetch" > 实际上是
< link rel =" prerender">< / rel =nofollow noreferrer> HTML 5 spec
贾斯汀不正确。你需要预取和预渲染（或至少一个polyfill将输出两个）作为 FF支持预取和 Chrome支持预渲染。
<!DOCTYPE html>
<meta charset="utf-8">
<title>An HTML Document</title>
<link rel="prefetch" href="https://www.apple.com/">
<link rel="prerender" href="https://www.apple.com/">
<script>
document.addEventListener('click', function () {
// Prerendering https://www.apple.com/ipad on Chrome.
// ...
// Prefetching https://www.apple.com/ipad on Firefox.
// ...
}, false);
</script>
When the page is opened, https://www.apple.com/ is prerendered and prefetched on different browsers. When the document is clicked, I hope to prerender and prefetch another page, https://www.apple.com/ipad.
It appears we have 2 methods to choose. We can either replace the URLs in current 2 link elements. Or we can insert 2 new link elements into head element.
What's the right method to set a new prerender in HTML?
What's the right method to set a new prefetch in HTML?
I tried to replace prerender link element's URL from https://www.apple.com/ to https://www.apple.com/ipad on Chrome. I turned Chrome's Task manager on and found that https://www.apple.com/ipad wasn't prerednered. The only prerendered page is still https://www.apple.com/. So it appears this method doesn't work?
<link rel="prefetch"> is actually part of the HTML 5 spec.
<link rel="prerender"> appears to be Google doing their own thing.
Justin is incorrect. You do need both prefetch and prerender (or at least a polyfill that will output both) as FF supports prefetch and Chrome supports prerender.
