需求1：选中默认设备，113 和114 和139都可以选中一个默认设备

选中多个默认设备方法：

async toSwitch(typeItem, title) {const res = await this.setDefaultDev(typeItem.ibdr_devsn, typeItem.ibdr_pid)if (!res) {this.common.toast('切换默认设备失败')return}const target = this.typeList.find(v => v.title === title)target.equipmentList.forEach(dev => {dev.ibdr_default_device = 20//设置为非默认设备})typeItem.ibdr_default_device = 10 // 设置默认设备this.common.toast(title + '已切换默认设备')},

需求2：选中一个默认设备，113 和114 和139  所有设备中只能选中一个

选中单个默认设备方法：

async toSwitch(typeItem, title) {const res = await this.setDefaultDev(typeItem.ibdr_devsn, typeItem.ibdr_pid)if (!res) {this.common.toast('切换默认设备失败')return}this.typeList.forEach(list => {list.equipmentList.forEach(dev => {dev.ibdr_default_device = 20//取消默认选中})})typeItem.ibdr_default_device = 10 // 设置默认设备this.common.toast(title + '已切换默认设备')},

绑定页面方式：

<template><view class="container tui-skeleton"><tui-skeleton v-if="skeletonShow" backgroundColor="#fafafa" borderRadius="10rpx"></tui-skeleton><view v-if="typeList.length>0 && !skeletonShow"><view class="typeBox" v-for="(typeItem,typeIndex) in typeList" :key="typeIndex"><view class="titleBox">{{typeItem.title}}</view><view v-for="(item,index) in typeItem.equipmentList" :key="index"><view class="my_toolListr" v-if="item.ibdr_default_device == 10"><view class="tool_item" @click="toSwitch(item, typeItem.title)":class="[index==typeItem.equipmentList.length-1?'noline':'',{'check_active':checkDefaultItem(item)}]"><view class="iconfont icon-checked" style="margin-right: 10rpx;"v-show="checkDefaultItem(item)"></view><!-- {{JSON.stringify(item)}} --><text class="text-style">{{item.ibdr_devsn}}<text v-if="item.ibdr_devsn!=item.ibdr_name">-{{item.ibdr_name}}</text></text></view><view class="tool-jtBtn" @click="toDevice(item)"><imgstyle="width:32rpx !important;height: 40rpx !important;"src="http://f.zstjj.com/f/uniapp/610097/static/img/icon/jt1.png" mode="widthFix" /></view></view><!--无默认的样式--><view class="my_toolListr" v-else><view class="tool_item tool-hui" @click="toSwitch(item, typeItem.title)"><view class="iconfont icon-checked" style="margin-right: 10rpx;"></view><text>{{item.ibdr_devsn}}<text v-if="item.ibdr_devsn!=item.ibdr_name">-{{item.ibdr_name}}</text></text></view><view class="tool-jtBtn" @click="toDevice(item)"><imgstyle="width:32rpx !important;height: 40rpx !important;"src="http://f.zstjj.com/f/uniapp/610097/static/img/icon/jt1.png" mode="widthFix" /></view></view></view></view></view><view v-else style="margin-top: 160rpx;display: flex;align-items: center;flex-direction: column;"><view><image src="http://f.zstjj.com/f/uniapp/610097/static/img/icon/zwsj.png"></image></view><view style="color: #8f8f8f;">暂无设备</view></view></view>
</template>

判断是否选中方法：

checkDefaultItem(item) {if (item.ibdr_default_device == 10) {return true}return false},
