Parse ID card number for js Verification

IDValidate. js

/**
* ID card 15-bit encoding rule: dddddd yymmdd xx p
* Dddddd: Location Code
* Yymmdd: Date of birth
* Xx: sequence class encoding, which cannot be determined
* P: gender. The odd number is male and the even number is female.
* <P/>
* ID card 18-bit encoding rule: dddddd yyyymmdd xxx y
* Dddddd: Location Code
* Yyyymmdd: Date of birth
* Xxx: sequence class code, which cannot be determined. The odd number is male and the even number is female.
* Y: Check Code. The value can be obtained through the first 17 digits.
* <P/>
* The 18-digit number weighting factor is (from right to left) Wi = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1]

* Formula for calculating the checkpoint: Y_P = mod (Σ (Ai × Wi), 11)
* I is the 2 .. 18 bits of the ID card number from right to left; Y_P is the position of the checkcode array where the ankle checkcode is located
