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>
i=1;
</script>
<center>
<form name="form1">
<select name="select01">
<option>11111 111111 111111111111</option>
<option>2222222</option>
<option>333333</option>
<option>4444444</option>
</select>
<span style="position:relative;left:-23px;width:17px;height:17px;font:7px 'wingdings 3';color:#cc0000;background:cyan;border:2px outset;text-align:center;padding-top:3px;cursor:default" onclick="if(i>=document.form1.select01.options.length){i=0}document.form1.select01.options[i].selected=true;i++">q
