话不多说,请看代码

function IsHKID(str) {
 var strValidChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
 // basic check length
 if (str.length < 8)
 return false;
 // handling bracket
 if (str.charAt(str.length-3) == '(' && str.charAt(str.length-1) == ')')
 str = str.substring(0, str.length - 3) + str.charAt(str.length -2);
 // convert to upper case
 str = str.toUpperCase();
 // regular expression to check pattern and split
 var hkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/;
 var matchArray = str.match(hkidPat);
 // not match, return false
 if (matchArray == null)
 return false;
 // the character part, numeric part and check digit part
 var charPart = matchArray[1];
 var numPart = matchArray[2];
 var checkDigit = matchArray[3];
 // calculate the checksum for character part
 var checkSum = 0;
 if (charPart.length == 2) {
 checkSum += 9 * (10 + strValidChars.indexOf(charPart.charAt(0)));
