django可选：无下拉列表

我想用django

我已经设置了一切，从我可以正确地告诉（见打击）。在FireBug中，正在发出请求并返回有效的JSON。一切正常，但没有显示结果。我已经包括了CSS

我为什么看不到下降的原因

FF有以下错误：

TypeError: this.menu is undefined
[Break On This Error]   

if ( this.menu.element.is( ":visible" ) ) {

这看起来是正确的，我认为：

1） 您没有按正确的顺序包含js文件

或

2） 您没有正确加载它们

将下面的内容添加到你的头部并删除你的链接，看看它是否有效

<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/
1.8.13/themes/ui-lightness/jquery-ui.css" type="text/css" />
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/
jquery/1.4.4/jquery.min.js"></script>
{{ form.media.js }}
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/
jqueryui/1.8.13/jquery-ui.min.js"></script>
{{ form.media.css }} 

{{form.media.js}
{{form.media.css}}

试试你的代码，它似乎可以工作。我认为它也是jQuery版本。谢谢
