实现类似IE地址栏功能的控件。我们想在html网页中实现类似 IE 地址栏http输入下拉框类似的控件，条件如下：1. 一个主要网页是 html 格式的，其中可以采用 Java Script 来实现。
2. 可以采用类似 Combobox控件的功能，具有“输入”和“选择”的功能。
3. 类似IE地址栏的输入框，输入一个网页地址或者任意字符串后，自动记忆到 IE 的cookies中或者其它设置中，可以通过IE清楚掉。
4. 在没有通过IE清楚之前，每次打开此html网页，把此前使用过的的相关地址都显示在combobox的下拉框条目之中，在input框中可以自动筛选。
5. 要求用html中的输入框和选择框组合实现，如有其它方案也可以考虑。
