需求：给了固定的label，叫xx单位，要输入单位的信息，但是属性名称都一样的，UI画图也是表单的形式，所以改为动态添加的形式，实现方式也很简单，循环就完事了，连着表单校验也动态

1.效果如下 

2.代码实现+讲解

因为需求是最后一个单位没有必要必填，所以在rules这里判断了一下，主要就是循环遍历了el-form-item，之后prop为了区分也是用index来区分了

 <el-dialog title="新建单位" :close-on-click-modal="false" :close-on-press-escape="false" :visible.sync="unitDialog" width="30%"><el-form:model="formInline"ref="unitRuleForm"label-width="130px"class="demo-form-inline"label-position="left"><el-form-itemv-for="(item, index) in formInline.formData":key="index":label="item.organizations_type":prop="'formData[' + index + '].organizations_name'":rules="index < formInline.formData.length - 1? {required: true,message: `${item.organizations_type}不能为空`,trigger: 'blur'}: null"><el-input v-model="item.organizations_name"></el-input></el-form-item></el-form><span slot="footer" class="dialog-footer"><el-button @click="unitDialog = false">取 消</el-button><el-button type="primary" @click="saveUnitData()">确 定</el-button></span></el-dialog>

formInline: {formData: [{project_id: 0,organizations_type: 'xx单位1',organizations_name: ''},{project_id: 0,organizations_type: 'xx单位2',organizations_name: ''},{project_id: 0,organizations_type: 'xx单位3',organizations_name: ''},{project_id: 0,organizations_type: 'xx单位4',organizations_name: ''},{project_id: 0,organizations_type: 'xx单位5',organizations_name: ''},{project_id: 0,organizations_type: 'xx单位6',organizations_name: ''}] //参建单位列表},
