举个例子，一下

<input type="checkbox" class="switch_checked" lay-filter="switchinfoid"
                   info_id="12344433"
                   lay-skin="switch" checked lay-text="上架|下架">

再看看js怎么写

    layui.use(['form'], function () {
        var form = layui.form;
        form.on('switch(switchinfoid)',function (data) {
            //开关是否开启，true或者false
            var checked = data.elem.checked;
            //获取所需属性值
            var info_id = data.elem.attributes['info_id'].nodeValue;
            console.log(checked);
            console.log(info_id );
            //TODO 此时进行ajax的服务器访问，如果返回数据正常，则进行后面代码的调用
            var serverStatus = 1;
            if(serverStatus){
                data.elem.checked = checked;
            }else {
                data.elem.checked = !checked;
            }
            form.render();
        });
    });
