允许保留小数点后两位
function (s) {
         var str = $.trim(s),
               reg1 = /[a-zA-Z\!\@\#\$\%\^\&\*\-\+\=\|\\\/\?]/g,
               reg2 = /^(\d*)(\.)(\d{1,2})(.*)$/g,
               reg3 = /^(0)/,
               reg4 = /(\.{1,})/g;
         return (((str.replace(reg1, "")).replace(reg2, "$1$2$3")).replace(reg3, "")).replace(reg4,".");
    }
