我现在有一个模板 <VerificationUser v-if="changePhoneData.popShow" v-show="changePhoneData.step === 2" :step-options="stepOptionsPC2" @fulfill="fulfillChangePhone($event)" @back="back" :loading="loading1" :key="2" buttonText="确认" msgType="UPDATE_MOBILE" > <div class="passwrod" slot="verify-before"> <van-field name="phone" v-model.trim="stepOptionsPC2.phone" validate-trigger="onBlur" :rules="[ { required: true, message: '请输入正确的手机号', pattern: patternPhone, }, ]" placeholder="请输入新的手机号" ></van-field> </div> </VerificationUser> 我想要在这个span打开它，应该改哪里 <div class="right" v-if="userinfo.authStatus == 1"> <span @click="nextStep" >查看实名</span> <img src="@/assets/img/棕色箭头-icon.png" alt="图片加载失败" /> </div>

你可以在 span 标签中添加一个 v-if 条件，当条件成立时渲染 VerificationUser 组件，如下所示：

<div class="right" v-if="userinfo.authStatus == 1">
  <span @click="changePhoneData.popShow = true" v-if="changePhoneData.step !== 2">修改手机号</span>
  <VerificationUser
    v-show="changePhoneData.step === 2"
    :step-options="stepOptionsPC2"
    @fulfill="fulfillChangePhone($event)"
    @back="back"
    :loading="loading1"
    :key="2"
    buttonText="确认"
    msgType="UPDATE_MOBILE"
  >
    <div class="passwrod" slot="verify-before">
      <van-field
        name="phone"
        v-model.trim="stepOptionsPC2.phone"
        validate-trigger="onBlur"
        :rules="[
          {
            required: true,
            message: '请输入正确的手机号',
            pattern: patternPhone,
          },
        ]"
        placeholder="请输入新的手机号"
      ></van-field>
    </div>
  </VerificationUser>
  <img src="@/assets/img/棕色箭头-icon.png" alt="图片加载失败" />
</div>

这样，当用户点击“修改手机号”时，会将 changePhoneData.popShow 设置为 true，然后渲染 VerificationUser 组件。当用户完成修改手机号后，组件会被隐藏，回到原先的状态。
