        <el-button size="mini" @click="addAdvices">添加建议事项</el-button>
      </el-form>

export default {
      ...
      data(){
        return {
          form:{
            name:'',
            address:{
              id:'',
              name:''
            },
            sponsor:[
              {id:'1',name:'Tom'},
              {id:'2',name:'Jack'}
            ],
            advices:[]
          },
          rules:{
　　　　　　　　//也可以写在data中
            //name:[{required:true,message:'不能为空',trigger:'blur'}],
            //'address.name':[{required:true,message:'不能为空',trigger:'blur'}],
            //'sponsor.0.name':[{required:true,message:'不能为空',trigger:'blur'}]//校验也可以这样写
          }
        }
      },

      methods:{
        deleteAdvices(idx){
          this.form.advices.splice(idx,1)
        },
        addAdvices(){
          let obj = {
            content:''
          }
          this.form.advices.push(obj)
        }
      }
    }
