来自rails jquery ajax的406错误

我在我的开发环境中工作。我想要的行为:我在模态对话框上有一个表单。用户单击提交,数据将发送到我的“问题”控制器。发送一些电子邮件,然后刷新对话框的内容以说“消息已成功发送”。很基本的。问题是我无法正确设置标头,因此rails将数据处理为html,而不是javascript。电子邮件发出但rails返回406错误。这是我的代码:

_social.html.erb

    <div class='jqmWindow notices' id="emailModal">
      <h3>Email a link to this poll</h3>
      <p>You are emailing a link to the following poll:<br><strong><%=@question.text%></strong></p>
      <%= form_tag(:controller=>'questions', :action=>'email' , :method => "post",  :id=>"emailForm") do %>
              <%= label_tag(:emails_label, "Enter up to 20 email addresses separated by commas:" )%>
          <%= text_area_tag(:emails, "",:size => "60x6")%>
          <%= hidden_field_tag(:question_id, @question.id )%>
              <%= label_tag(:email_msg_label, "Enter a brief message to accompany your link:" )%>
          <%= text_area_tag(:email_msg, "",:size => "60x4")%><br>

          <%= submit_tag ( "Submit")%>
        <%end%>
    </div>

...

<script>

$(document).ready(function(){
  $('#shareModal').jqm();
  $('#emailModal').jqm();
  $.ajaxSetup({
    'beforeSend': function(xhr) {
        xhr.setRequestHeader("Accept", "text/javascript")
    }
  });


  $(document).ajaxSend(function(e, xhr, options) {
    var token = $("meta[name='csrf-token']").attr("content");
    xhr.setRequestHeader("X-CSRF-Token", token);
  });

...

  $('#emailForm').submit(function(){
    $.post($(this).attr('action'), $(this).serialize(), null, "script");
    return false;
  });
});

</script>

questions_controller.rb

 def email
    question = Question.find(params[:question_id])
    emails = params[:emails].split(/, /)
    emails.each do |recipient|
      GenericMailer.share(question, current_user.email, recipient, params[:email_msg]).deliver
    end
    respond_to do |format|
      format.js
    end


  end

email.js.erb(现在,此代码永远不会被执行!)

alert("hello!");
$(#emailModal).html("Email sent successfully!");

以下是标题:

感谢所有回复的人。事实证明,ajax代码从未被执行过。这是铁路问题。这是罪魁祸首:

<%= form_tag(:controller=>'questions', :action=>'email' , :method => "post",  :id=>"emailForm") do %>

id被附加到请求中,而不是作为css id添加到表单标记中。因此,jQuery选择器没有捕获表单提交。正确的代码:

<%= form_tag({:controller=>'questions', :action=>'email' }, {:id=>"emailForm"}) do %>

...干杯

答案 1 :(得分:0)

看来你的ajaxSetup可能不正确,JS的官方MIME类型是application/javascript

在标题中,您可以看到Accept:字符串中没有JS的内容。 首先尝试调用附加了.js的URL来排除你的Rails控制器。

然后在浏览器检查器中确保application/javascript在接受列表中排在第一位。

答案 2 :(得分:0)

您是否在email.js.erb中调试了javascript / jquery代码? 406错误通常表示你的js代码中的拼写错误(这对于错误代码的含义并不明显)。

至少,在您的示例中,第二行有拼写错误,缺少单引号:

 $('#emailModal').html("Email sent successfully!");
