Question

我一直在到处找，不明白为什么这不起作用。

我正在尝试测试一个非常基本的ajax操作。这是我的代码：

控制器：

def commit
    respond_to do |format|
        format.html { redirect_to :action => "index" } # see note 1
        format.js { render :layout => false } # see note 2
        format.js { render :nothing => true } 
    end
end

看法

<%= link_to "commit", :action => "commit", :remote => true %>
<%= form_tag( :action => "commit", :remote => true, :method => :post) do %>
     <%= submit_tag "commit" %>
<% end %>

<div id= message ></div>

commit.js.erb

console.log( committed );
$( #message ).html("committed");

The problem is I d get to the commit method, but the page would reload, which defeats the point of remote=>true Also the commit.js never seemed to get called.

Note 1: If I exclude this line, I get the blank page to /commit. Including it makes the page just reload
Note 2: I ve tried both of these approaches suggested by other SO posts
Note 3: I ve tried both using link_to and form_tag

有人能帮忙吗？谢谢

Answer 1

你为什么放两行？

    format.js { render :layout => false } # see note 2
    format.js { render :nothing => true }

移除第二个！

代替

<%= link_to "commit", :action => "commit", :remote => true %>

具有

<%= link_to "commit", commit_path, :remote => true %>

The same with the form:

让您：

<%= form_tag( :action => "commit", :remote => true, :method => :post) do %>

像

<%= form_tag(commit_path, :remote => true) do %>

注意：POST是默认行为，您可以从form_tag中省略它。
