推荐答案

正确"在这种情况下是一个棘手的词 ;) .有人可能会问，为什么不只是采用 button 元素并使其看起来像一个链接?

"Correct" is a tricky word in this context ;) . One could ask why you're not just taking a button element and make it look like a link?

无论如何 - 您无法使用纯 HTML 实现这一点(至少据我所知).使用 Javascript 框架，例如jQuery 你可以简单地做这样的事情:

Anyways — you can't achieve this with plain HTML (at least not to my knowledge). With a Javascript framework like e.g. jQuery you could simply do something like this:

$('a').click(function(){
    $('form').submit();
    return false;
});

Rails 2.3.x 有一个 link_to_remote 帮助器，让您指定 :submit 参数(= DOM 元素的 ID，默认为父表单).所以你可以写:

Rails 2.3.x had a link_to_remote helper which let's you specify a :submit parameter (= DOM element's ID, default is the parent form). So you were be able to write:

link_to_remote 'submit', :url => {…}, :submit => "my_form"

但是随着 Rails 3 向 UJS 的推动，这个助手消失了.

But with Rails 3's push to UJS, this helper is gone.
