效果

效果如下，靓号部分会显示红色

实现思路

1、定义正则规则
2、遍历手机号，生成一个由0和1组成的11位字符串，1表示靓号，0不为靓号
3、在HTML中循环手机号，根据下标给数字添加类名light，即高亮

JS代码

javascript">getBeautifulPhone (phoneNum) {
  // 正则规则
  var regexArrs = [
    {
      regex: /(123|234|345|456|567|678|789|987|876|765|654|543|432|321){2}/,
      type: '双顺子'
    },
    {
      regex: /(\d)\1{2,}/,
      type: 'AAA'
    },
    {
      regex: /(\d{3,4})\1/,
      type: 'ABCDABCD'
    },
    {
      regex: /12345|23456|34567|45678|56789|98765|87654|76543|65342|54321|78910/,
      type: '事业靓号'
    },
    {
      regex: /(\d)\1(\d)\2/,
      type: 'AABB'
    },
    {
      regex: /(\d)(\d)\1\2/,
      type: 'ABAB'

    }
  ]
  phoneNum = String(phoneNum)
  var phoneColors = '00000000000'
  var phoneType = ''
  for (var index = 0; index < regexArrs.length; index++) {

HTML代码

javascript"><div class='phone'>
  // 高亮的添加类名light
  <span
	v-for="(num, i) in phoneInfo.phoneNums"
	:key="i"
	:class="{light: phoneInfo.phoneColors[i] == 1}">
    {{num}}
  </span>
</div>

CSS代码

javascript">.light{
  color: red;
}
