data中有一個(gè)數(shù)組，包含多個(gè)對象。將多個(gè)對象數(shù)據(jù)循環(huán)放入列表。

data:{

items: [
    {
      id: 336,
      title: '智利三文魚扒500g酸甜口味爆炒',
      img: '../assets/images/test/8-1.jpg',
      rechargeMoney: 1,
      price1: 106,
      price2: 80
    },
    {
      id: 337,
      title: '西班牙三文魚扒500g酸甜口味爆炒',
      img: '../assets/images/test/8-1.jpg',
      rechargeMoney: 2,
      price1: 225,
      price2: 152
    }
  ]

}
<input v-if="!item.isGray" v-model="item.rechargeMoney" type="tel" placeholder="￥請輸入金額">

    rechargeMoneyFun:function (type,idx) {

        if(type == "min"){
            if(this.cardsArray[idx].rechargeMoney == ""){
                return;
            }else if(this.cardsArray[idx].rechargeMoney <= 100){
                return;
            }else if(parseInt(this.cardsArray[idx].rechargeMoney)-100 <=100 ){
                return;
            }else{
                this.cardsArray[idx].rechargeMoney -= 100;
            }
        }else if(type = "add"){
            if(this.cardsArray[idx].rechargeMoney == ""){
                this.cardsArray[idx].rechargeMoney =100;
            }else{
                var num = parseInt(this.cardsArray[idx].rechargeMoney);
                num += 100;
                this.cardsArray[idx].rechargeMoney = num;
            }
        }
    }

this.cardsArray[idx].rechargeMoney 這個(gè)數(shù)據(jù)是已經(jīng)變化了的，data中items數(shù)據(jù)最開始是空的，請求接口后，循環(huán)添加的。但是在input上value值沒有變化。求教
