element ui upload 删除文件

直接上代码

<el-form-item label="身份证照片（正反照）">
	// 这里设置ref
      <el-upload action="#" ref="upload" list-type="picture-card" :auto-upload="false" :limit="2">
      <i slot="default" class="el-icon-plus"></i>
        <div slot="file" slot-scope="{ file }">
            <img class="el-upload-list__item-thumbnail" :src="file.url" alt="" />
            <span class="el-upload-list__item-actions">
                <span class="el-upload-list__item-preview" @click="idCardPreview(file)">
                    <i class="el-icon-zoom-in"></i>
                </span>

                <span v-if="!disabledIdCard" class="el-upload-list__item-delete" @click="idCardRemove(file)">
                    <i class="el-icon-delete"></i>
                </span>
            </span>
        </div>
    </el-upload>
    <el-dialog :visible.sync="dialogVisibleIdCard">
        <img width="100%" :src="dialogImageUrlIdCard" alt="" />
    </el-dialog>
</el-form-item>

 // 身份证删除  方法如下
idCardRemove(file) {
     // console.log(file);
     // 实现缩略图模板时删除文件
     let fileList = this.$refs.upload.uploadFiles;
     let index = fileList.findIndex((fileItem) => {
         return fileItem.uid === file.uid;
     });
     fileList.splice(index, 1);

	// 还有一个方法  不过这个方法是删除全部已选文件
	this.$refs.upload.clearFiles();//调用element官方的方法
 }
