第一种:徒手写一个简单的步骤线

template

<div class="per-mobile-step"
          v-for="(item,index) in steps"
          :key="item.value"
          @click="changeStep(item,index)"
          :class="[
            'per-mobile-step-'+index,
            item.value==currentcomponent?'active':'',
            index < currentcomponentindex?'active':''
          ]">
            <div class="title-dot">
              <i :class="[
                  item.value==currentcomponent?'active':'',
                  index < currentcomponentindex?'actived':''
                ]"></i>
              <div class="line" 
                :class="[
                  index < currentcomponentindex?'active':''
                ]" 
                v-if="index!==3"></div>
            </div>
            <div class="title-text"
            :class="[
              'title-text-'+index,
              item.value==currentcomponent?'active':'',
              index < currentcomponentindex?'active':''
            ]">{{item.label}}</div>
          </div>

上面的

index < currentcomponentindex?'active':''

为了记录当前步骤前的已完成的步骤,actived为已完成,active为当前展示步骤


js

data(){
    return{
      currentcomponent:"ac1",
      currentcomponentindex:0,
      steps:[
        {
          label:"身份验证",
          value:"ac1"
        },
        {
          label:"手机号绑定",
          value:"ac2"
        },
        {
          label:"设置密码",
          value:"ac3"
        },
        {
          label:"完成",
          value:"ac4"
        },
      ]
    }
  },
