andv vue 实现多张图片上传

1、提示

注意：：： 便利出来的数组 点击保存需要 把 双引号去掉

 this.formData.image = this.imageUrlList.filter((image) => image !== '')

注意：：： 回显的时候需要 再把 双引号加上

  this.imageUrlList = data.image.split(',')

        this.imageUrlList.unshift('') //落地页回显

目的是未来 "" 数组的第一项数据 是给 上传使用的 里面有判断 k==0 的时候 显示上传按钮 是添加操作

有时候还需要检测 数组里面是不是只要 一个 空字符串

  if (this.imageUrlList.includes('')) {
        } else {
          this.imageUrlList.unshift('') //落地页回显
        }

2、具体代码如下

   <div
                v-for="(itemd, k) in imageUrlList"
                class="qdsng"
                :key="k"
                style="display: inline-block; position: relative"
              >
                <!-- {{ itemd }} -->
                <a-upload
                  v-if="k == 0"
                  name="avatar"
                  list-type="picture-card"
                  class="avatar-uploader"
                  :show-upload-list="false"
                  :before-upload="beforeUploads"
                  :onRemove="handleRemove"
                  multiple
                  style="padding: 0"
                >
                  <div class="ant-upload-text">上传</div></a-upload
                >
                <a-upload
                  v-else
                  name="avatar"
                  list-type="picture-card"
                  :show-upload-list="false"
                  :before-upload="beforeUploads"
                  :onRemove="handleRemove"
                  id="uploadi"
                >
                  <div v-if="itemd != ''" style="width: 100%; height: 100%; margin: 0 auto">
                    <img
                      v-if="itemd != ''"
                      :src="itemd"
                      alt="avatar"
                      style="width: 100%; height: 100%"
                      @click="uploadd(k)"
                    />
                  </div>
                  <div v-if="itemd == ''">
                    <div class="ant-upload-text" @click="uploadd(k)">上传</div>
                  </div>
                </a-upload>
                <div
                  v-if="itemd != ''"
                  style="
                    position: absolute;
                    top: -2px;

                  @click="handleReset(k)"
                >
                  <a-icon type="close" size="20px" />
