        <div class="step-txt">

            <van-icon v-if="active > step.id" name="checked" color="#1989fa" size="20" style="background: #FFFFFF;"/>

    <button @click="active = 0 ">0</button>
    <button @click="active = 1 ">1</button>
    <button @click="active = 2 ">2</button>

  </div>

js
基于vue

import {reactive, ref} from "vue";

const active = ref(0);
const stepArray = reactive([
  {
    id:0,
    name:'合同信息',
    detail:'填写合同信息',
  },
  {
    id:1,
    name:'合同模板',
    detail:'填写合同信息',
  },
  {
    id:2,
    name:'合同发起',
    detail:'预览和发起',
  }
])
