How to make a button work as a link in erb?
提问by usr
<%= link_to 'New Post', new_post_path %>
This produces link to new_post_path. Previously i used <input type="submit" class="new" name="Addlist" value="Add New" />which resembled like a button. So how can i make the link look like button in erb?
这会产生指向new_post_path. 以前我用过<input type="submit" class="new" name="Addlist" value="Add New" />它，就像一个按钮。那么我怎样才能让链接看起来像 erb 中的按钮呢？

Just to throw another option out there since I had a scenario where the button_to option didn't work. This looks kind of similar to that.
只是为了抛出另一个选项，因为我有一个 button_to 选项不起作用的场景。这看起来有点像那个。
<%= link_to '<button type="button">New Post</button>'.html_safe, new_post_path %>
What I basically wanted is a button that doesn't turn into a submit, since I have multiple buttons on the page that aren't related to a form, and I really just want it to just go to another page.
我基本上想要的是一个不会变成提交的按钮，因为我在页面上有多个与表单无关的按钮，我真的只想让它转到另一个页面。

Take a look at button_to. In summary it will be simmilar to this:
看看button_to。总之，它将类似于：
<%= button_to "New Post", { :action => "new" }, :method => :get %>
Although be aware, this method accepts the :methodand :confirmmodifiers described in the link_todocumentation. If no :methodmodifier is given, it will default to performing a POSToperation. You can also disable the button by passing :disabled => truein html_options. If you are using RESTful routes, you can pass the :methodto change the HTTP verb used to submit the form.
尽管请注意，此方法接受文档中描述的:method和:confirm修饰符link_to。如果没有:method给出修饰符，它将默认执行一个POST操作。您也可以通过传递禁用按钮:disabled => true在html_options。如果您使用 RESTful 路由，您可以传递:method来更改用于提交表单的 HTTP 动词。

@Ryan's answer is good but sadly failshtml validation http://validator.w3.org/
@Ryan 的回答很好，但遗憾的是未能通过html 验证http://validator.w3.org/
error: The element button must not appear as a descendant of the a element.
错误：元素按钮不得作为 a 元素的后代出现。
Why not simply apply a (CSS) classto your link and make it appearas a button.
为什么不简单地将 (CSS)类应用到您的链接并使其显示为按钮。
erb:
erb：
<%= link_to "Button Text", new_post_path, class: 'button' %>
<%= link_to "Button Text", new_post_path, class: 'button' %>
produces (valid& semantic) HTML:
产生（有效和语义）HTML：
<a class="button" href="/post/new">Button Text</a>
<a class="button" href="/post/new">Button Text</a>
which you can then styleto looklike a button.
然后您可以将其样式设置为看起来像一个按钮。
