我没有新的节目，但那种生锈在Javascript / Web开发。我建立使用Rails应用程序，我们必须在此期间，我们要提供反馈给用户一些耗时的操作。基本上，我想要做的事该使用AJAX这样的：

[用户单击确定或继续] [可选确认框] 在显示状态消息，说工作......，而操作发生 当操作完成并返回数据从服务器，状态消息更改为完成！其结果呈现或一些回调发生。

这已经有一段时间，因为我做了网络的发展，以及如何实现这样的一个简单的例子是非常有益的。谢谢你。

解决方案

  $（窗口）.ajaxStart（函数（）{
    $（＃装载机）显示（）。
}）。ajaxStop（函数（）{
    $（＃装载机）隐藏（）。
}）;
 

只是全球绑定到启动和停止。这个例子显示和隐藏装载机股利。通常你有它让用户微调一个div知道它加载。

微调的消失应该够了，完成的消息，是矫枉过正。

I am not new to programming, but kind of rusty in Javascript/web development. I am building an application with Rails, and we have several time-consuming operations during which we want to provide feedback to the user. Basically, I want to do something like this using AJAX:

[User clicks 'ok' or 'proceed'] [Optional confirmation box] Show a status message saying "Working..." while the operation takes place When the operation finishes and data returns from the server, status message changes to "Done!" and the results are rendered or some callback occurs.

It has been a while since I did web development, and a simple example of how to achieve something like this would be very helpful. Thank you.

解决方案

$(window).ajaxStart(function() {
    $("#loader").show();
}).ajaxStop(function() {
    $("#loader").hide();
});

Just globally bind to start and stop. This example shows and hides a loader div. Generally you have a div with a spinner in it letting the user know that it is loading.

The disappearance of the spinner should be enough, a "done" message is overkill.
