循环表单，rules失效问题

1、循环数据必须是表单v-mode的数据
2、prop命名问题

  <el-form class="form " :model="dataCollection" label-width="120px" size="small"
       	 :rules="rulesCollection"  ref="dataCollection">
			<div v-for="(val, index) in dataCollection.incomeList" :key="index">
				el-form-item :label="'进账金额' + (index + 1)" 
				:prop="'incomeList.' + index + '.incomeMoney'"
		         :rules="rulesCollection.incomeMoney"> <el-input v-model="val.incomeMoney"
		       @change="incomeMoneyFun(val.incomeMoney, index)"  @input='provingChange($event,"incomeMoney")'>					           </el-input>
	 </el-form-item>
 </div>
 </form>

rulesCollection: { 
		incomeMoney: { required: true, trigger: "blur",  message: "请输入进账金额" },
 },

provingChange（）为input框无法输入内容解决的方法

 provingChange(e,name){
      this.$delete(this.dataCollection,name)
      this.$set(this.dataCollection, name, e);
    },
