uniapp 单项选择 可用于支付方式选择

<view @click="check('item', index)"><image :src="item.checked ? checkedImg : uncheckedImg" class="oil-check" mode=""></image></view>
				

上述src可以修改为阿里巴巴矢量font

check(type, indexs) {
			let cartList = that.youpin.map((item, index) => {
				item.checked = false;
				if (indexs == index) {
					item.checked = true;
				}
				return item;
			});
			that.youpin = cartList;
		},

 切换函数

let cartList = list.map((item, index) => {
				item.checked = false;
				if (index == 0) {
					item.checked = true;
				}
				return item;
			});

预处理数据 默认选择第0个
