jQuery是一个功能非常强大的javascript类库。
昨天把网上的入门教程整理了一下。颇有心得。
由于比较喜欢Django文档的样式所以就把它的文档样式表下载下来了（偷懒！）。
然后我又用jQuery修改了一下文档的结构：

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
        $('div.document')
        .wrap("<div id='container'><div id='columnwrap'><div id='content-main'></div></div></div>");
        if (jQuery.browser.mozilla) {
            $('#content-main').after('<div id="content-related" class="sidebar"></div>');
            $('div[@class="contents topic"]').appendTo('#content-related');
        }
    });
</script>

今天在Ext Forum上看到了一个djangoExt的扩展：http://extjs.com/learn/Extension:ServerForm
所以可以考虑先在django的静态页面中生成form的html代码，
或者在需要显示表单时向服务器请求表单内容，再通过Extjs渲染。
现在有两个问题要先解决：

1. 数据关联的ComboField如何实现
2. 文件上传的字段问题

最近安装了PCBSD的最新版本，发现一个问题！
无论我怎么设置，lo0的地址就是不会设置！
我按照论坛上的说明：在/etc/rc.conf中加ifconfig_lo0 = 127.0.0.1不行！
还修改了一个什么文件，现在都忘记了！没有效果。
还发现eclipse很容易崩溃！
konqueror也经常崩溃，有时插上U盘，会导致死机！
总之问题多多！比ubuntu难用多了。

其实早就对BSD家族的成员很感兴趣了。FreeBSD的中文资料多些，所以接触也就多些了。但FreeBSD安装起来太麻烦了，要3张CD！ PCBSD就好多了，感觉FreeBSD的内核精简而强悍！Linux好像就要差些了。 但是Linux的发行版ubuntu实在是很好用。而且有很好的中文社区。 FreeBSD的中文社区就不行了，我题的问题就没有人回答（现在我快放弃BSD了）！
