前端 对身份证号和手机号的验证及模糊处理

一，身份证号的模糊处理

          

userIdCard.replace(/^(\d{6})\d+(\w{4})$/, "\$1********\$2")

 

二，手机号的模糊处理

           

tel.replace(/^(\d{3})\d+(\d{4})$/, '\$1****\$2')

 

三，手机号的验证

function validatePhoneNum (phoneNum) {
    const reg = /^1[0-9]{10}$/
    return reg.test(phoneNum)
  }
