ElementPlus el-upload上传组件on-change只触发一次

主要运用了:on-exceed方法

废话不多说，直接上代码

          <el-upload
            class="avatar-uploader"
            action=""
            :on-change="getFilesj"
            :limit="1"
            :auto-upload="false"
            accept="image/png, image/gif, image/jpg, image/jpeg"
            :show-file-list="false"
            ref="uploadImage"
            :on-exceed="handleExceed"
          >
            <img
              v-if="showImg"
              :src="showImg"
              class="avatar"
            />
            <el-icon v-else class="avatar-uploader-icon"><Plus /></el-icon>
          </el-upload>

const uploadImage = ref(null);
function handleExceed(files) {
  uploadImage.value.clearFiles();
  const file = files[0];
  file.uid = genFileId();
  uploadImage.value.handleStart(file);
}
