element ui form循环嵌套表单 及嵌套表单的验证方法（校验）_两个elform 嵌套

首先看看成果

表单一级、二级嵌套的增加、删除

一级、二级嵌套 的 表单的验证

下图添加了样式区分一级二级嵌套，与上图是一样的

知识点

一级嵌套

循环：<div v-for="(item, index) in form.producte" :key="index">
prop绑定：:prop="`producte[${index}].name`"
规则绑定：:rules="{
                      required: true,
                      message: '基本名称不能为空',
                      trigger: 'blur',
                    }"

二级嵌套

循环：<div v-for="(item1, index1) in item.rules" :key="index1"> //item为上面一级中的item，下面的producte同理
prop绑定：:prop="`producte[${index}].rules[${index1}].ruleName`"                      
规则绑定：:rules="{
                   required: true,
                   message: '域名不能为空',
                   trigger: 'blur',
                   }"

代码展示

直接复制到你的 vue 中就可以展示和进行测试

有问题的话可以提问（数据都是随便写的）
