代码如下 | 复制代码 |
functionIsHKID(str) { varstrValidChars ="ABCDEFGHIJKLMNOPQRSTUVWXYZ" // basic check length if(str.length < 8) returnfalse; // 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 varhkidPat = /^([A-Z]{1,2})([0-9]{6})([A0-9])$/; varmatchArray = str.match(hkidPat); // not match, return false if(matchArray ==null) returnfalse; // the character part, numeric part and check digit part varcharPart = matchArray[1]; varnumPart = matchArray[2]; varcheckDigit = matchArray[3]; // calculate the checksum for character part varcheckSum = 0; if(charPart.length == 2) { checkSum += 9 * (10 + strValidChars.indexOf(charPart.charAt(0))); checkSum += 8 * (10 + strValidChars.indexOf(charPart.charAt(1))); }else{ checkSum += 9 * 36; checkSum += 8 * (10 + strValidChars.indexOf(charPart)); } // calculate the checksum for numeric part for(vari = 0, j = 7; i < numPart.length; i++, j--) checkSum += j * numPart.charAt(i); // verify the check digit varremaining = checkSum % 11; varverify = remaining == 0 ? 0 : 11 - remaining; returnverify == checkDigit || (verify == 10 && checkDigit =='A'); } |
在网上找了很久都没合意的验证方式,最后通过Google找到一个国外写的js验证,发现可以使用。
上面那段验证的很精密,包含身份证真实性的校验,如果只是想验证输入的香港身份证格式,请使用下面的这段js。
