Rails - link_to和button_to

Question

在我的Rails 3.2.3应用程序中，我使用的是Ajax和jQuery。网页上有一个链接，我想用一个按钮替换它。下面的代码工作完美

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

但是这一次不

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

结果HTML中的链接和按钮是在这里

#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> 

我做了什么错？

Answer 1

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

会给一个ID，输入

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

Answer 2

根据文档remote选项应该是options的一部分。见http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-button_to

Answer 3

您必须更改方法:method=>:get，因为默认情况下它设置为post。和你的路线可能不是正确的路由，

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