效果如下:

参考代码:

后端url: disparamModule/disparamInit返回的数据结构

一. html代码

<div class="distribution-set-container">
  <!-- 面包屑导航 -->
  <Bread :fromFather="dataPath"></Bread>
  <!-- 主体内容 -->
  <div class="content">
    <!-- 等级升级及所需积分设置 -->
    <div class="upgrade">
      <div class="title">
        <h3>等级升级及所需积分设置</h3>
        <div class="numButton">
          <a href="#" @click.prevent="addGrade">新增等级</a>
          <a href="#" @click.prevent="delGrade">删除等级</a>
        </div>
      </div>

      <div
        class="list"
        v-for="(item,index) in numData.userLev"
        :key="index"
        v-show="index+1 <= showNumber"
      >
        <span>{{ item.code | fmtgrade }}</span
        ><input v-model="item.remarks" /> <span>升级所需积分数</span
        ><input v-model="item.codeValue" />
      </div>
    </div>
  </div>
</div>

二. css(less)代码

.distribution-set-container {
  color: #000;
  .content {
    text-align: left;
    height: 710px;
    width: 100%;
    background-color: #fff;
    box-shadow: 2px 2px 5px #e6e6e6;
    box-sizing: border-box;
    overflow-x: auto;
    .upgrade {
      .title {
        display: flex;
        justify-content: space-between;
        align-items: center;
        height: 80px;
        .numButton {
          a {
            display: inline-block;
            width: 100px;
            height: 24px;
            background-color: #0085f4;
            text-align: center;
            margin-left: 30px;
            color: #fff;
          }
        }
      }
      .list {
        padding: 0 14px;
        height: 60px;
        line-height: 60px;
        background-color: #f5faff;
        span {
          margin-right: 18px;
          vertical-align: middle;
        }
        input {
          margin-right: 80px;
          border: 1px solid #0085f4;
          height: 24px;
          vertical-align: middle;
          padding: 0 10px;
          width: 100px;
        }
      }
    }
  }
}

三. js代码

    Bread // 注册面包屑组件
  },
  data() {
    return {

          name: '分销参数设置',
          path: 'distribution-set'
        }
      ], // 面包屑数据
      numData: {}, // 总数据
      showNumber: 0
    }
  },
  filters: {
    // 局部过滤器,英文等级转中文
    fmtgrade(grade) {
      switch (grade) {
        case 'one':
          grade = '一级'
          break

          break
        case 'nine':
          grade = '九级'
          break
        case 'ten':
          grade = '十级'
          break
      }
      return grade
    }
  },
  methods: {

      }
    },
    addGrade() {
