试图弄清楚Ruby on Rails远程:真正的回调

Question

所以我一直在谷歌搜索如何设置它们,我最终得到了这个代码.

<script>

$('#reportform')
    .bind("ajax:success", function(data, status, xhr) {
        $('#reportalert').text('Done.');
    });
    .bind("ajax:error", function(xhr, status, error) {

        $('#reportalert').text('Failed.');

    });

</script>


<h2>Review Driver</h2>
<p>Fill out your review of the driver</p>   

<div class="hero-unit form-signin" id="reportformdiv">

    <%= form_for(@report, html: { id: "reportform" }, remote: true, update: 
    { success: "response", failure: "error"} ) do |t| %>
<p id="reportalert"></p>
    <%= t.text_field  :plant_site,    placeholder: "Plant Site" %>

    <%= t.text_field  :route_number,  placeholder: "Route Number" %>

    <%= t.text_field  :driver_name,   placeholder: "Driver name if available" %>

    <%= t.date_select :date_recorded, html: { class: "input-block-level" } %>

    <%= t.text_field  :action,        placeholder: "Action taken" %>

    <%= t.text_area   :report_body,   placeholder: "What you witnessed",
                                     style: "height: 300px;",
                                     class: "input-block-level" %>

    <%= t.submit     "File Report",  class: "btn btn-primary btn-large" %>

    <% end %>

</div>

但它不起作用,我不知道为什么,我确定我做错了什么,我是RoR的新手,我喜欢这样一个事实:我可以声明这个遥远:真实的形式是它的自我,一旦我弄清楚如何设置回调我会很高兴:)提前感谢.

Answer 1

根据Rails的wiki,下面的代码应该工作:

<script>
  $(document).ready(function(){
    $('#reportform').on('ajax:success', function(e, data, status, xhr){
      $('#reportalert').text('Done.');
    }).on('ajax:error',function(e, xhr, status, error){
      $('#reportalert').text('Failed.');
    });
  });
</script>

在Rails 3.2.14和jquery-rails 3.0.4中,类似的代码对我有用

希望能帮助到你.

由于 Rails 5.1，响应、状态和 xhr 必须通过 event.detail 提取，请参阅：https ://edgeguides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers

这是一种可能的解决方案：

$(document).on('ajax:success', '#reportform', event => {
  const [response, status, xhr] = event.detail;
});
