我有一个包含谷歌地图只（图通过JavaScript）的索引文件。当我搜索一些地方，还销其附近的地图，现在是很好的。但我要的是，当过我点击标记在地图上。它应该显示的地方细节的DIV地图下方在同一页上。我在阿贾克斯的资产/ JavaScript的/ customer.js，指向URL在控制器/客户/索引的客户控制器，我得到了整个页面的响应。这就是我们所知道的是错的。这是我的js文件内容

I have an index file which contains google map just (map through javascript) . when I search some place, it also pins its nearby on the map that's good now . But what I want is , when ever I click on marker on the map . It should show a div of place detail on the same page below the map . I made ajax assets/javascript/customer.js , pointing the URL at customer controller in controller/customers/index I get the whole page in response . that's we know is wrong . Here is my js file content

$.ajax({
  url: "/",
  async: false,
  method: "post",
  data: { "place_id" : place["place_id"] },
  success: function(data){
       alert('success');
     }
   });
   infoWindow.open(map, marker);
   buildIWContent(place);
});

和我的控制器的功能是

def index
  if params[:place_id]
    @place = Places.find(params['place_id'])
  end
end

这就是我要在我的索引页即html.erb

And this is what I want to show in my index page i.e html.erb

<% if @place %>
  <div class='place-name'><% @place.name %></div>
<% end %>

我知道有在轨支持的谐音，但我不知道那些将工作或没有。我是新来的Rails所以原谅我，如果你发现我的问题很愚蠢的。 我只是想表明通过AJAX魔术这个地名分区，无论是通过谐音，或只是因为它是。

I know there are partials supported in rails but I don't know whether those will work or not . I'm new to Rails so pardon me if you find my question very silly. I just want to show this place-name div through ajax magic, whether through partials or just as it is.

推荐答案

要解决你的问题，你不得不修改了一些code在这里。首先，你必须修订您的Ajax请求方法和网址为：

To fix you problem, you have to revised some code here. First, you have to revised your ajax request method and url into:

$.ajax({
  url: "/customers",
  async: false,
  method: "GET",
  data: { "place_id" : place["place_id"] },
  success: function(data){
       alert('success');
     }
   });
   infoWindow.open(map, marker);
   buildIWContent(place);
});

它会显示警告，当你做访问用户索引页面。 然后。在您的索引方式，尽量要做到这一点：

It will show alert when you've done to access the customers index page. Then. In your index method, try to do this:

def index
  if params[:place_id]
    @place = Places.find(params['place_id'])
  end
  respond_to do |format|
    format.html
    format.js
  end
end

然后。你必须创建新的文件 index.js.erb的包含

$('.place-name').text('<%= @place %>');

这只是雏形。你必须用自己的方式来定制

It's only prototype. You have to customize with your own way
