For letters with a base greater than 10, the letters represent numbers greater than 9. For example, for hexadecimal numbers (base 16), use a through F.
If no base is specified, the preferred base is assumed to be 10.
var x='110'; alert(parseInt(x,2)); //6 =>以2进制解析110 alert(parseInt(x,8)); //72 =>以8进制解析110 alert(parseInt(x,16)); //272 =>以16进制解析110
