如何使用jQuery AJAX請求和Ruby on Rails'render'方法來實現？
[英]How to use the jQuery AJAX request and the Ruby on Rails 'render' method togheter?
I am using Ruby on Rails 3.0.7 and jQuery 1.6.1 and I would like to know how to handle response xhr, status and ex variables after an AJAX request.
我正在使用Ruby on Rails 3.0.7和jQuery 1.6.1，我想知道如何在AJAX請求之后處理響應xhr，status和ex變量。
The AJAX request is:
AJAX請求是：
$jQuery.ajax({
type: "POST",
url: "<request_to_the_controller_method>", // see the code below
error: function(xhr, status, ex) {
// handling with 'xhr', 'status' and 'ex' variables
}
success: function(jqXHR, status, ex) {
// handling with 'xhr', 'status' and 'ex' variables
}
});
In the controller I have:
在控制器中我有：
respond_to do |format|
format.js {
render ... # here should be properly stated the Ruby on Rails 'render' method
:status => 200
}
end
How SHOULD be stated in the controller the render method to respond to the AJAX request so that it is possible to handle response values (xhr, status and ex variables) in the error or success section of the AJAX request? Then, how can I handle the response values after I retrieved those (for example to show those values in an alert message)?
應該如何在控制器中聲明render方法來響應AJAX請求，以便能夠在AJAX請求的錯誤或成功部分處理響應值（xhr，status和ex變量）？那么，在檢索到響應值之后如何處理響應值（例如在警報消息中顯示這些值）？
In few worlds, what I would like to do is (in the controller) to respond to an AJAX request with some data and then (on the other side) handle this data.
在少數世界中，我想做的是（在控制器中）用一些數據響應AJAX請求，然后（另一方面）處理這些數據。

as well for details. Here's an excellent article on the topic of rails, the Rails jQuery UJS driver, jQuery, and rails.js
以及細節。這是關於rails，Rails jQuery UJS驅動程序，jQuery和rails.js主題的優秀文章
- It finds remote links, forms, and inputs, and overrides their click events to submit to the server via AJAX.
- 它找到遠程鏈接，表單和輸入，並覆蓋其單擊事件以通過AJAX提交到服務器。
- It triggers six javascript events to which you can bind callbacks to work with and manipulate the AJAX response.
- 它觸發六個javascript事件，您可以綁定回調以使用和操作AJAX響應。
And then the article walks through how to do all this using jQuery, UJS and rails.
