Answer 1

尝试下面的代码接受'-'也作为计数

^[0-9-]{5,10}(?:-[0-9]{4})?$

{5,10} => accepts min length 5 and max-length 7 you can change accordingly

 'zip': [null, {validators: [ Validators.required, Validators.pattern('^[0-9-]{5,7}(?:-[0-9]{4})?$')]}],


  12345        //output - true
  12345-3456   //output - true
  1234         //output - false
