Question

我在尝试使用控制器中呈现的内容显示弹出窗口（fancybox）时遇到问题。 Fancybox始终显示消息“无法加载请求的内容。”

以下是我正在尝试的代码：

<%= link_to new_item_path(:format => 'js'), :remote => true, :class => 'new_item_popup fancybox.ajax', do %>
    <div class="bubble">
        Add a quick item
    </div>
<% end %>

<script>
    $(document).ready(function(){
        $("#feedback_form").hide();

        $(".new_item_popup").fancybox({
            type        : 'ajax',
            maxWidth    : 800,
            maxHeight   : 600,
            fitToView   : false,
            width       : '70%',
            height      : '70%',
            autoSize    : false,
            closeClick  : false,
            openEffect  : 'none',
            closeEffect : 'none'
        });
    });
</script>

我发现Firebug的有趣之处在于，此代码几乎同时触发了两个new.js请求。我想知道这是否是造成这个问题的原因。

使用Rails 3.0，使用jQuery 1.7.1，最新的rails.js和Fancybox 2.0.4。

以下是application.html.erb的内容，以防万一：

  <%= javascript_include_tag 'jquery-1.7.1.min', 'rails', 'application' %>
  <%= javascript_include_tag 'jquery-ui-1.8.9.custom.min' %>
  <%= javascript_include_tag 'jquery.prettyPhoto' %>
  <%= javascript_include_tag 'jquery.fancybox.pack' %>
  <%= javascript_include_tag 'iphone-style-checkboxes' %>
  <%= javascript_include_tag 'placeholder' %>
  <%= csrf_meta_tag %>

通过将fancybox类型参数更改为“iframe”，我可以看到弹出窗口。但随后它会在弹出窗口中显示整个网站，而不仅仅是响应。

更新：原来这个双ajax请求是由application.html.erb中的这一行引起的：

 <%= javascript_include_tag 'jquery-1.7.1.min', 'rails', 'application' %>

通过从那里删除'rails'，双重调用也被删除。尽管答案是正确的（通过Firebug检查），fancybox仍然不会显示内容。以下是我试图通过Fancybox显示的回复内容：

<div id="create_new_item_window">
    <div class="margin_b"><h2>Create new item</h2></div>
    <div>
    <form accept-charset="UTF-8" action="/items" class="simple_form item" enctype="multipart/form-data" id="new_item" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="RaCmpqXV17piSDljz5VWl0y2INxHTrO5VREAczn+wY4=" /></div>

            <div class="image_attachment">
                <div class="attachment_text">

                </div>
                <div class="attachment_button">
                    <input id="item_assets_attributes_0_photo" name="item[assets_attributes][0][photo]" type="file" />
                </div>
            </div>
            <div class="image_attachment">
                <div class="attachment_text">
                    Add a receipt <br><small>(JPG, PNG or PDF, max 500kb)</small>
                </div>
                <div class="attachment_button">
                    <input id="item_receipts_attributes_0_photo" name="item[receipts_attributes][0][photo]" type="file" />
                </div>
            </div>
        </div>
        <a href="#" id="hide_advanced_section_link" class="amaranth">Hide details</a>
        <div class="margin_r">
            <input class="button small_button white right" data-disable-with="Saving..." id="item_submit" name="commit" type="submit" value="Create Item" />
        </div>
</form>    </div>
</div>

<script type="text/javascript">  
$(function(){  
    $("#show_advanced_section_link").click(function(event) {  
        event.preventDefault();  
        $("#show_advanced_section_link").hide();
        $("#hide_advanced_section_link").show();
        $("#new_item_advanced_section").slideDown();
    });
    $("#hide_advanced_section_link").click(function(event) {  
        event.preventDefault();  
        $("#hide_advanced_section_link").hide();
        $("#new_item_advanced_section").slideUp();
        $("#show_advanced_section_link").show();
    });
});

$(document).ready(function(){
    $("#new_item_advanced_section").hide();
    $("#hide_advanced_section_link").hide();
});

$(function(){  
    $( "#datepicker3" ).datepicker({
            changeMonth: true,
            changeYear: true
        });
});
</script>

更新2：尝试使用jquery初始化ajax调用，并按照注释中的建议将结果传递给Fancybox。不起作用，Fancybox根本不显示：

$(function(){
    $('.fancybox').click(function(event) {
        event.preventDefault();
        $.ajax('/items/new.js', {
            success: function(result) {
                $.fancybox({ content: result ,type : 'inline', maxWidth : 800, maxHeight : 600, fitToView : false, width : '70%', height : '70%', autoSize : false, closeClick : false, openEffect : 'none', closeEffect : 'none' });
            }
        });
    });
});

也尝试了这样（相同的结果）：

$(function(){
    $('.fancybox').click(function(event) {
        event.preventDefault();
        $.ajax('/items/new.js', {
            success: function(result) {
                $(result).fancybox();
            }
        });
    });
});

ajax请求本身工作正常，收到正确的响应。

带有Fancybox的Rails：不显示ajax内容
