显示、隐藏密码

请参考这个程序: ?php //$day 星期几,如:星期三 $day=3; ? html head
meta “Content-Type” content=”text/html; charset=gb2312″ meta
name=”GENERATOR” content=”Microsoft FrontPage 4.0″ meta name=”ProgId”
content=”FrontPage.Editor.Document” titletest/title /head body
onload=”window.form1.day.value=?php echo $day ; ?” FORM action=””
method=POST id=form1 name=form1 SELECT id=day name=day size=”1″ option
value=”1″星期一/option option value=”2″星期二/option option
value=”3″星期三/option option value=”4″星期四/option option
value=”5″星期五/option option value=”6″星期六/option option
value=”7″星期日/option /SELECT /FORM /body /html 触类旁通,利用
window_onload 可以很巧妙的实现一些默认项的选取。 希望对大家有所帮助。
请笑纳。
