element-ui upload文件上傳,清空文件列表

1.上傳組件中需要綁定ref屬性 ref="upload"

                  <el-upload
                    ref="upload"
                    action="http://localhost:8082/api/Product/imageUpload"
                    :data="ProductImageUploadData"
                    :on-success="getImageByProductId"
                    accept=".png,.jpg,.gif,jpeg,.bmp"
                    list-type="picture-card"
                    :multiple="true"
                    :on-preview="handlePictureCardPreview"
                    :on-remove="handleRemove">
                    <i class="el-icon-plus"></i>
                  </el-upload>

2.在對應的函數中使用

 this.$refs.upload.clearFiles()

即可清空
