即时发布“prerender”？(Issue “prerender” 'on the fly'?)

 是否有可能发布prerender语句“即时”？ 例如我使用jQuery来插入它 
 
<link rel="prerender" href="www.example.com" />
 
 进入和它会执行？ 有没有办法重新发布它x次？ 
 
 基本上，当某人向购物车中添加了某项内容时，我想预先显示结帐页面，但很明显，我无法在网页加载时执行此操作，因为它会在没有添加新项目的情况下预渲染结帐页面。 
 
 谢谢 

Is it possible to issue a prerender statement 'on the fly'? e.g. I use jQuery to insert this in
 
<link rel="prerender" href="www.example.com" />
 
into the and it will execute? Is there a way to re-issue it x times?
 
Basically, when someone adds something to the shopping cart I want to prerender the checkout page, but obviously I can't do that at page load because it will prerender the checkout page without the new item added.
 
Thanks
