一、首先看最终效果 

先说下整体逻辑,选中状态为淡紫色,点击哪个金额,充值页面上就显示多少金额 

二、代码 

	<view class="addMoney">
				<view class="addMoneyTittle">
					充值金额
				</view>
				<view class="selfaddmoney" :class="{'selfaddmoney1':isActive}">
					<text>自定义交费</text> <input @focus="isActive = true" @blur="isActive = false" type="text"
						v-model="addmoney" class="selfinput"><text class="selfinputtext">元</text>
				</view>
				<view class="moneyLaut">
					<view class="money" v-for="(item,index) in money" @click="addmoneyValue(index)"
						:class="{'active':selectedIndex === index}">
						{{item.money}}<text class="selfinputtext">元</text>
					</view>
				</view>
			</view>



data() {
			return {
				show: false,
				show1: false,
				showOverlay: false, // 控制overlay显示与否的变量
				appointmentStatus: true, // 假设初始状态为预约失败  
				selectedOldMan: 0,
				selectedIndex: null, // 用于存储当前选中的元素索引

				}],
				money: [{

					money: 1000
				}, {
					money: 2000

					money: 3000
				}, {
					money: 5000
				}, {
					money: 10000
				}, ],
				addmoney: 15000,
				isActive: false
			}
	addmoneyValue(index) {
				this.selectedIndex = index; // 设置当前选中的索引  
				this.addmoney = this.money[index].money;
			},
