Rails - link_to和button_to

Question

在我的Rails 3.2.3應用程序中，我使用的是Ajax和jQuery。網頁上有一個鏈接，我想用一個按鈕替換它。下面的代碼工作完美

<%= link_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :remote => true,:id => 'lnk_more' %> 

但是這一次不

<%= button_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :remote => true,:id => 'lnk_more' %> 

結果HTML中的鏈接和按鈕是在這裏

#link 
<a href="/home/test_method?page=1" data-remote="true" id="lnk_more" disabled="disabled">More </a> 


#button 
<form action="/home/test_method?page=1" class="button_to" data-remote="true" method="post"><div><input id="lnk_more" type="submit" value="More "><input name="authenticity_token" type="hidden" value="hFCuBR+88FYKEvNTZok+QRhxf6fHA+ucC6i2yc9hBEk="></div></form> 

我做了什麼錯？

Answer 1

<%= button_to "More", 
    { :controller => :home, :action=> :test_method, :page => @current_page}, 
    { :remote => true, :id => 'lnk_more' } 
%> 

會給一個ID，輸入

<input id="lnk_more" type="submit" value="More"> 

Answer 2

根據文檔remote選項應該是options的一部分。見http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-button_to

Answer 3

您必須更改方法:method=>:get，因爲默認情況下它設置爲post。和你的路線可能不是正確的路由，

<%= button_to "More", {:controller => "home", :action => "test_method", :page=>@current_page }, :method=>:get, :remote => true,:id => 'lnk_more' %>
