如上图我想点击立即对换然后获取到这一条数据的数据，但是我现在点击兑换，获取到的是所有数据的值而不是这一条数据的值

<view class="activity-watch-exchange" data-index="1" bindtap="exchangeIntegral" >立即兑换</view>

async exchangeIntegral(event) {

let arrs = this.data.integralList.activitySpecial;

let query = event.currentTarget.dataset['index'];

console.log(event.currentTarget.dataset['index'],"event.currentTarget.dataset['index']");

console.log(arrs,);

for(let i of arrs){

// console.log(i.id,'i.id')

}

console.log(arrs[0].id,'i.id')

let param = {

personId:'11',

goodsId: '11111'

}

let res = await oilWeChatAppService.exchangeIntegral(param);

// debugger

if (res.success) {

wx.showToast({

title: '成功兑换',

icon: 'success',

image: '../../resource/imgs/warning.png',

duration: 2000

})

}
