Question

使用jQuery提交表单时出现406 Not Acceptable错误。我尝试过在网络上找到的常见修补程序：

jQuery.ajaxSetup({ 
  'beforeSend': function(xhr) {
    xhr.setRequestHeader("Accept", "text/javascript");
  }
})

这还没有解决问题。 request.format输出text / html。我一整天都试图解决这个问题。 Rails 2.3.4，jQuery 1.3.2和jQTouch。

这是我的jquery代码：

jQuery(function () {
  $("#search").submit(function (e) {
    var $form = $(this);
    return app.search($form);
  });
});

var app = {
  search:function ($form) {
    $.ajax({

      type:$form.attr("method"), url:$form.attr("action"),
      dataType:"script", data:$form.serialize(),
      complete:function (req) {
        if (req.status === 200 || req.status === 304) {
        } else {
          alert("There was an error searching. Try again.");
          console.log(this);
        }
      }
    });    
    return false;
  }
};

表格：

  %form{:action => "/search", :method => "post", :id => "search", "accept-charset" => "utf-8"}
    %div{:style =>"margin:0;padding:0;display:inline" }
      %input{:name => "_method", :type => "hidden", :value => "put"}
      %input{:name => "authenticity_token", :type => "hidden", :value => "#{form_authenticity_token}"}
    %ul.rounded
      %li
        %input{:name => 'query', :value => '', :type => 'text', :placeholder => "Search"}

控制器代码：

  def show
    query = params[:query]
    @results = Person.search(query)
    respond_to do |wants|
      wants.html { }
      wants.js 
    end   
  end

show动作是一个叫做的动作。我已经确认，这是日志

Answer 1

好的，我发现了我的问题。我正在使用jqtouch插件进行rails，它会自动为开发模式下的请求分配：iphone格式，这会强制我没有的format.iphone。我用这段代码来覆盖：

if request.xhr? && request.format == :iphone
  request.format = :js
end

Answer 2

正确的方法是编辑（或添加）config/initializers/mime_types.rb以接受:iphone次请求。

Mime::Type.register_alias "text/javascript", :iphone

Rails和jQuery产生406错误
