Ruby on rails 3 ajax：远程提交表单时未调用succuess 3

基本上，我想提交一个createnewcourse表单，并使用JQuery处理响应。 我的身体像

<div id="create_coursem">
  <%= form_tag({:controller => "coursem", :action => "create"}, :id => "check_coursem_form", :method => "post", :remote => true) do %>
      <p>
      <b> <%= label_tag(:name, "Name:") %> </b>
      <%= text_field_tag(:name) %>
      </p>
      <p>
      <b> <%= label_tag(:department, "Department:") %> </b>
      <%= select_tag "department", @result.html_safe %>
      </p>
      <%= submit_tag("Create") %>

  <% end %>

</div>

响应状态为200，这意味着它成功返回了json。在我的JS文件中，我有

$(document).ready(function() {
    panelHandler();
    //showOverview();
    showResources();
    resourceHandler();
    calendarChangeMonth();
    subscribeHandler();

    shownewresourceform();

    eventinfo();
    closeeventbox();
    showneweventform();
    colorrecentevents();
    check_coursem();
})
    function check_coursem() {
        $("form#check_coursem_form").on('ajax:beforeSend', function(xhr, settings) {alert("hello");})
                                .on('ajax:success',    function(data, status, xhr) {alert("hello");})
                                .on('ajax:complete', function(xhr, status) {alert("hello");})
                                .on('ajax:error', function(xhr, status, error) {alert("hello");});
    }

但是当我单击create按钮时，它只返回create控制器生成的json，没有显示任何警报。有人知道原因吗？

非常感谢。

我还没有使用过ajax，但我从未见过这样的请求格式。。。 您是否尝试过在中实现更类似的功能

也许它试图将响应解析为javascript响应，而不是json响应

试试这个：

form_tag({:controller => "coursem", :action => "create"}, :id => "check_coursem_form", :method => "post", :remote => true, :data => { :type => 'json' }) do %>

// Assign handlers immediately after making the request,
// and remember the jqxhr object for this request
var jqxhr = $.ajax( "example.php" )
    .done(function() { alert("success"); })
    .fail(function() { alert("error"); })
    .always(function() { alert("complete"); });

// perform other work here ...

// Set another completion function for the request above
jqxhr.always(function() { alert("second complete"); });

form_tag({:controller => "coursem", :action => "create"}, :id => "check_coursem_form", :method => "post", :remote => true, :data => { :type => 'json' }) do %>
