flex布局一行显示，显示不下的省略号显示

因为整个头部是flex布局，detail为右侧占flex：3 1 1，并没有设置固定的宽度，当box设置不换行时，拿到的宽度是整个box的宽度,会导致如下样式超出问题

所以需要把detail设置width:0，并且超过一行部分省略号显示。

全体源码如下：

<template>
  <view class="houseInfo">
    <view class="top">
      <view class="title">委托房屋</view>
      <view class="btn" @tap="editHouse" v-if="showEditBtn">修改坐落</view>
    </view>
    <view class="info">
      <view class="box">
        <view class="label">楼盘</view>
        <view class="value">{{ houseDetail.communityName }} </view>
      </view>
      <view class="box">
        <view class="label">楼栋号</view>
        <view class="value">{{ houseDetail.comBuildingName || "-" }}</view>
      </view>
      <view class="box">
        <view class="label">房间号</view>
        <view class="value">{{ houseDetail.roomNo || "-" }}</view>
      </view>
    </view>
  </view>
</template>

<script>
export default {
  props: ["houseDetail", "showEditBtn"],
  data() {
    return {};
  },
  created() {},
  mounted() {},
  methods: {
    editHouse() {
      this.$emit("editHouse");
    },
  },
};
</script>

<style lang="less" scoped>
.houseInfo {
  width: 622rpx;
  height: 168rpx;
  background: #ffffff;
  border-radius: 12rpx;
  .top {
    display: flex;
    justify-content: space-between;
    .title {
      margin-bottom: 24rpx;
      font-size: 36rpx;
      font-weight: bold;
      color: #303133;
      line-height: 54rpx;
    }
    .btn {
      color: #247257;
      font-size: 28upx;
    }
  }
  .info {
    display: flex;
    justify-content: space-between;
    align-items: center;
    .box {
      width: 0;
      &:nth-child(1) {
        flex: 3;
        margin-right: 32rpx;
        border-right: 1rpx solid #f0f2f5;
      }
      &:nth-child(2) {
        margin-right: 32rpx;
        flex: 1;
      }
      &:nth-child(3) {
        flex: 1;
      }
      .label {
        margin-bottom: 8rpx;
        font-size: 28rpx;
        color: #909199;
        line-height: 42rpx;
      }
      .value {
        font-size: 32rpx;
        font-weight: bold;
        color: #303133;
        line-height: 48rpx;
        width: 100%;
        overflow: hidden;
        white-space: nowrap;
        text-overflow: ellipsis;
      }
    }
  }
}
</style>

小插曲：四边阴影设置box-shadow: 0 8rpx 26rpx 0 rgba(0, 0, 0, 0.13);
