使用mockjs生成随机手机号码

使用mockjs

const Mock = require('mockjs')
// 拓展mockjs
Mock.Random.extend({
  phone: function () {
    var phonePrefixs = ['132', '135', '189'] // 自己写前缀哈
    return this.pick(phonePrefixs) + Mock.mock(/\d{8}/) //Number()
  }
})
console.log(Mock.Random.phone())
// 生成 1 - 10 个 随机手机号码
let { phone } = Mock.mock({
  'phone|1-10': ['@phone']
})
console.log(phone)
// [ '13521629423', '13527482540', '18979012768' ]

// 或者使用其他方式等等
const phonePrefix = ['132', '135', '189']
const index = Math.floor(Math.random() * phonePrefix.length)
var phone = phonePrefix[index] + Mock.mock(/\d{8}/)
console.log(phone)

使用自定义函数

function Mock() {}

Mock.mobile_prefix = [
  '132',
  '135',
  '136'
]

Mock.numeric = '0123456789'

Mock.random = function (len, list) {
  if (len <= 1) {
    len = 1
  }
  var s = ''
  var n = list.length
  if (typeof list === 'string') {
    while (len-- > 0) {
      s += list.charAt(Math.random() * n)
    }
  } else if (list instanceof Array) {
    while (len-- > 0) {
      s += list[Math.floor(Math.random() * n)]
    }
  }
  return s
}

Mock.getMobile = function () {
  return Mock.random(1, Mock.mobile_prefix) + Mock.random(8, Mock.numeric)
}

console.log(Mock.getMobile())
