            <!-- <div class="detail_title">{{ item.title }}</div> -->
            <div class="detail_content">

                v-for="item in classesDict"
                :class="{ checkedclass: selectedclass == item.value }"
                :key="item.value"
                class="detail_box"
                @click="checkedclassitem(item)"
              >
                {{ item.studentClass }}
              </div>
            </div>
          </div>
        </div>
        <div class="btn_box">
          <div class="submit-btn" @click="confimclass()">确定</div>
        </div>
      </div>
    </van-popup>

:lock-scroll="false"加了这个属性就可以了具体去看官网。

然后苹果手机卡顿情况是pop里层的设置的z-index大于了pop本身的默认z-idenx2008，设置成一样的就可以了。
