一看到这个问题我就想到要用正则，懒得写，狗狗下，便有了如下代码
- <script>
- function cc(s){
- if(/[^0-9\.]/.test(s)) return "invalid value";
- s=s.replace(/^(\d*)$/,"$1.");
- s=(s+"00").replace(/(\d*\.\d\d)\d*/,"$1");
- s=s.replace(".",",");
- var re=/(\d)(\d{3},)/;
- while(re.test(s))
- s=s.replace(re,"$1,$2");
- s=s.replace(/,(\d\d)$/,".$1");
- return "￥" + s.replace(/^\./,"0.")
- }
- </script>
- <input onchange="this.value=cc(this.value)">
