<view wx:if="{{switchAllChecked}}">
    <view class="index-bottom" wx:for="{{siteList}}" wx:for-item="item" wx:key="item">
        <view class="bottom-content">
            <text>{{item.name}}</text>
            <switch data-id="{{item.id}}" bindchange="switchThisChange" />
        </view>
    </view>
</view>

Page({
	switchThisChange(e){
		//获取当前触发的id值
		let currentId = e.currentTarget.dataset.id;
	}
)
