Vue 自定义带数字的(1,2,3,4,...)分页组件

效果图如下：

组件代码：

<template>
    <div class="paging flex flex-center-cz flex-center-sp">
      <div class="flex flex-space-between ">
        <div class="flex">

            <div class="flex flex-center-cz margin-left-s font-s color-gray">共<span class="count">{{recordCount}}</span> 条</div>

          <img class="logo-18 margin-s pointer" style="transform: scaleX(-1)" src="@/assets/images/icon/next.png" @click="prior" />
          <div class="pointer color-gray font-l margin-right-s margin-left-s flex flex-center-cz" v-for="num in pageList" :key="num" @click="valueChange(num)"
              :class="{ 'highLight': num === selectedNumber }">
            {{ num }}
          </div>
          <img class="logo-18 margin-s pointer" src="@/assets/images/icon/next.png" @click="next"/>


          <div class="flex flex-center-cz margin-left-s font-s">转到</div>
          <input type="number" style="width: 50px;" v-model="pgIndex" class="num margin-left-s margin-right-s" @change="pageChange" />
          <div class="flex flex-center-cz font-s">页</div>

        </div>
      </div>
  
  
    </div>
