jQuery的，阿贾克斯，POST功能，滑轨

问题描述

我是个Rails的新手，有一个关于从阿贾克斯发布到Rails控制器，以及将数据返回给JavaScript的问题。我是pretty的不熟悉这实际上是如何工作的，但我已经拼凑其他SOF线程工作岗位功能。现在，我张贴从一个简单的按钮，点击数据，以及阿贾克斯code是这样的：

I am a Rails newbie and have a question about posting from ajax to a rails controller, and returning the data to javascript. I'm pretty unfamiliar with how this actually works, but I've pieced together a working post function from other SOF threads. Right now, I'm posting the data from a simple button click, and the ajax code looks like this:

$.ajax({
  type    : 'POST',
  url     : "http://localhost:3000/fbusers",
  data    : { tester : { name : 'boom' } },
  success : function(data) {
              alert(data);
            },
});

下面是code控制器，它的pretty的简单：

Here is the code in the controller, its pretty simple:

def create
  @user = User.create( params[:tester] )
end

这code正常工作，把数据上传到创建功能，它创建（职位？）项的分贝。不过，我想回的数据后，报警功能的成功。但现在，该警报只是返回对象[对象]。谁能帮我交的数据传递到报警功能？如果可能的话，解释（或方向的基础教程）将极有帮助。

This code works fine to post the data to the create function, which creates (posts?) the entry to the db. But I would like to return the data in the alert function upon "success." But right now, the alert just returns object[object]. Can anyone help me pass the post data into the alert function? If possible, an explanation (or direction to a basic tutorial) would be extremely helpful as well.

在此先感谢！

推荐答案

我假设你想返回给用户。在这种情况下，我建议：

I assume you want to return the user. In this case i recommend:

def create
  @user = User.create( params[:tester] )
  respond_to do |format|
    format.html
    format.json  { render :json => @user}
  end
end

然后只是使Ajax调用请求的JSON

And then just make the ajax call request the json
