微信小程序自定义列表单选，定义一个表示为0，循环列表中index判断是否与当前的标识一样。

通过点击事件改变标识

<view class="tr {{pvalue == idx?'active':''}}" wx:for="{{4}}" wx:for-index="idx" data-name="{{idx}}" bindtap="onRadioClick">
				<view class='td td-md'>AC-13-001</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<view class='td'>35%</view>
				<image class="ico" src="{{pvalue == idx?'../../assets/images/dui.png':'../../assets/images/dui-w.png'}}"></image>
			</view>

data: {

		pvalue: '0',
	},
	onRadioClick(event) {
		const {name} = event.currentTarget.dataset;
		console.log(event.currentTarget.dataset)
		this.setData({
			pvalue: name,

	},
