select发展史 超强第1/2页

作者：marvellous
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:

select,option {background-color:lime}

1
2
不是一样的嘛

select,option {background-color:lime;font-family:华文行楷;color:red;}

上海
北京
香港

日久天长之后,人们对select要求高了,要修一修边幅:

i=1;

11111 111111 111111111111
2222222
333333
4444444

=document.form1.select01.options.length){i=0}document.form1.select01.options[i].selected=true;i++">q
