密码框简单制作,还可以替换成自己想用得符号. <BR>#c { position: relative; } <BR>#a { position: absolute; left: 0; top: 0; font-size: 12px; font-family: 宋体; } <BR>#b { position: absolute; left: 0; top: 0; font-size: 12px; font-family: 宋体; -moz-opacity:0;opacity: 0;filter: alpha(opacity=0); } <BR> <style type="text/css"> #c { position: relative; } #a { position: absolute; left: 0; top: 0; font-size: 12px; font-family: 宋体; } #b { position: absolute; left: 0; top: 0; font-size: 12px; font-family: 宋体; -moz-opacity:0;opacity: 0;filter: alpha(opacity=0); } </style> <div id="c"> <input id="a"> <input id="b" onkeyup="document.getElementById('a').value=this.value.replace(/./g,'◆');"> </div> [Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
