    }

    .img-col {
        height: 140px;
        line-height: 140px;
        border: 1px dashed #c0ccda;
        border-radius: 6px;
        background-color: #fbfdff;
        text-align: center;
        position: relative;

        .el-icon-plus {
            font-size: 40px;
            color: #8c939d;
        }

        .el-image {

                font-weight:bold;
            }
        }
    }
</style>

二、组件使用

1、引入组件

import identityCardUpload from '@/components/identityCardUpload'

2、注册组件

components: { identityCardUpload  },

3、使用组件

<el-col :span="12">
                <el-form-item label="身份证图片:">
                    <identity-card-upload :editable="true" tableName="t_entity" :keyId="edit.entityId"
                                          :cardFrontList.sync="edit.cardFrontList" :cardReverseList.sync="edit.cardReverseList" name="查看" />
                </el-form-item>
            </el-col>

三、效果

点击按钮
