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:
<style>
select,option {background-color:lime}
</style>
<select>
<center>
<option>1
<option>2
<option>不是一样的嘛</select>日久天长之后,人们对select要求高了,要修一修边幅:
<br><br>
<script>

<center>
<form name="form1">
<select name="select01">
<option>11111 111111 111111111111</option>
<option>2222222</option>
<option>333333</option>
<option>4444444</option>
</select>
