Rails Dropzone错误:html class =" fallback"重新加载页面后更改

标签: javascript jquery html ruby-on-rails

我在rails视图中有一个带有dropzone和file_tags的表单:

<%= form_tag '/media_contents', method: :post, class: 'dropzone form', id: 'media-dropzone' do %> <div class="fallback"> <%= file_field_tag 'media', multiple: true %> </div> <% end %>

当我开始显示html视图时,我得到了这个类:

&#13;
&#13;
<form method="post" accept-charset="UTF-8" action="/media_contents" id="media-dropzone" class="dropzone form">
    <input type="hidden" value="✓" name="utf8">
    <input type="hidden" value="ksbt9hMvy3RCzFzqiRJpq+MBw5gbqy/rlWZ7mL1tOGnRjfv+CRWdLrVCdxXJyFCYL73A5H4Vb9lWl+fRA4rE7Q=="
           name="authenticity_token">
    <div class="fallback">
        <input type="file" multiple="multiple" id="media" name="media">
    </div>
</form>
&#13;
&#13;
&#13;

但是在我重新加载这个页面后,我在文件输入中获得了新的html元素:

&#13;
&#13;
<form method="post" accept-charset="UTF-8" action="/media_contents" id="media-dropzone" class="dropzone form dz-clickable">
    <input type="hidden" value="✓" name="utf8">
    <input type="hidden" value="WZZn20j4veF2OtEMK12qR06tkGtPpNsgst/Kkan9SyAa3XHTUsLru4G0+vNrh5N0ghGTFyoamxJxLlbYFxq3pA=="
           name="authenticity_token">
    <div class="dz-default dz-message"><span>Drop files here to upload</span></div></form>
&#13;
&#13;
&#13;

我想得到第二个视图,而不是第一个视图。但我不知道为什么,以及如何删除第一个视图。请帮忙
