(编辑：jimmy 日期: 2024/12/23 浏览：2)
参考elementUI官网以及网上的其他一些资料。话不多说，直接贴代码。
htmt部分：
<div id="app" style="width: 500px;">
<el-form :model="environmentForm" ref="environmentForm">
<el-row :gutter="24" v-for="(item, index) in environmentForm.items" :key="item.key">
<el-col :span="6">
<el-form-item :prop="'items.' + index + '.name'"
:rules="{required: true, message: '名称不能为空', trigger: 'blur'}">
<el-input v-model="item.name"></el-input>
</el-form-item>
</el-col>
<el-col :span="6">
<el-form-item :prop="'items.' + index + '.variable'"
:rules="{required: true, message: '变量值不能为空', trigger: 'blur'}">
<el-input v-model="item.variable"></el-input>
</el-form-item>
</el-col>
<el-col :span="3" v-if="environmentForm.items.length !== 1">
<el-button @click="removeEnvironmentForm(item)" class="el-icon-delete" size="mini" circle>
</el-button>
</el-col>
<el-col :span="3">
<el-button @click="addEnvironmentForm" size="mini" class="el-icon-plus" circle></el-button>
</el-col>
</el-row>
<el-form-item>
<el-button type="primary" @click="submitForm('environmentForm')">提交</el-button>
<el-button @click="resetForm('environmentForm')">重置</el-button>
</el-form-item>
</el-form>
</div>
实现效果:单个时
多个时显示删除按钮
