js中输入数字自动货币格式化

js方法-------------------

function moneyType(s){

        if(/[^0-9\.]/.test(s)) {return s;}
        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.")
        

        }

可在return前加货币符号；
