本文旨在大家对select和模拟select有一个全面地了解,使此项技术能发挥出更高的水平。

最初的select的确很平淡,就是一个下拉选项列表:

运行代码框
<style> select,option {background-color:lime} </style> <select> <center> <option>1 <option>2 <option>不是一样的嘛</select> <style> select,option {background-color:lime;font-family:华文行楷;color:red;} </style> <select name="select" onfocus="this.options[0].innerText='上海'"> <option value="上海">上海</option> <option value="北京">北京</option> <option value="香港">香港</option> </select>
[Ctrl+A 全部选择提示：你可先修改部分代码，再按运行]

日久天长之后,人们对select要求高了,要修一修边幅:
