Cannot read properties of undefined (reading ‘row‘)

简介: Cannot read properties of undefined (reading ‘row‘)

今天敲代码遇到了一个bug

自己原先的代码:

 <el-table-column
                    align="right">
                    
                        <el-button
                              type="primary"
                              plain
                              style="width: 50px; font-size: 13px"
                              >修改</el-button
                            >
                            <el-popconfirm
                                confirmButtonText="好的"
                                cancelButtonText="不用了"
                                icon="el-icon-info"
                                iconColor="red"
                                @confirm="deleteStudent(scope.row.id)"
                                title="这是一段内容确定删除吗?">
                            <template #reference>
                        <el-button type="danger">删除</el-button>
                        </template>
                    </el-popconfirm>
                <!-- </template><template v-slot="scope"></template> -->
         </el-table-column>

改好的代码:

<el-table-column
                    align="right">
                    <template v-slot="scope"><el-button
                              type="primary"
                              plain
                              style="width: 50px; font-size: 13px"
                              >修改</el-button
                            >
                            <el-popconfirm
                                confirmButtonText="好的"
                                cancelButtonText="不用了"
                                icon="el-icon-info"
                                iconColor="red"
                                @confirm="deleteStudent(scope.row.id)"
                                title="这是一段内容确定删除吗?">
                            <template #reference>
                        <el-button type="danger">删除</el-button>
                        </template>
                    </el-popconfirm>
                </template>

<template v-slot="scope">将template的标签改成这样
