非常感谢
  能详细点吗 ?最好附有html的   谢谢了
大概意思一下
<script type="text/javascript">
function aa(obj)
{
var value = obj.value.replace(/\D/g, "-");
if(value.substring(value.length - 1, value.length) == "-")
value = value.substring(0 , value.length - 1); obj.value = value;
}
</script>
<input id="a" name="a" type="text" onFocus="javascript:aa(this);">
给我50分
以下2个日期格式化方法(下面的代码最好单独放一个js文件)
一个是字符串转时间,一个是时间转字符串(这个是梅花雪的)使用方法:
字符串转日期:
var aa = new Date();
aa.setFormatDate("2007年2月10日 15:16:20","yyyy年MM月dd日 hh:mm:ss");
aa.setFormatDate("2007--2--10 15/16/20","yyyy--MM--dd");
aa.format = "yyyy/MM/dd hh:mm:ss";
aa.setFormatDate("2007/2/10 15:16:20");
以上3个是将 "日期字符串" 以 "日期格式" 转换成日期
其中日期字符串必须比格式字符串要完整否则无法转换日期转字符串:
var aa = new Date();
aa.Format("yyyy年MM月dd日 hh:mm:ss");
aa.Format("yyyy-MM-dd");
....以后怎么用就不用我说了吧

其实chuckcoin()的基本上实现了    只是要将原来的覆盖掉
而楼上的好像把效果给做错了.

onFocus触发这个好象不太稳定，实在不行就把onChange和onBlur都加上，或者onMouseMove也可以考虑...
