实例:
报错:Cannot read property ‘itemGroupList‘ of undefined"
解决方法:在itemGroupList上一层判断一下父级元素
<div v-if="table2.itemCat"> <div v-for="(itemgrounp,indexgrounp) in table2.itemCat.itemGroupList" :key="indexgrounp"> <div> <div style="display:flex;juistify-content:flex-start;margin:10px"> <span>分组名:</span> <el-input v-model="itemgrounp.group_name" placeholder="请输入分组名称" class="grounp_name"></el-input> <el-button @click="deleteBygroundid(indexgrounp)" type="danger" icon="el-icon-delete" style="height:40px;margin-left:15px" circle></el-button> </div> </div> </div>
Cannot read property 'XXX' of undefined"
