<div class="layui-col-xs4">

这个是开关按钮

<div class="layui-col-xs4">
<label class="layui-form-label">是否影响线路强送电</label>
<c:if test="${log.isEfectSendElec==null || log.isEfectSendElec=='不影响'}">
<input type="checkbox" name="isEfectSendElecclose" id="isEfectSendElec" lay-skin="switch" lay-filter="switchText"
lay-text="是|否">

</c:if>
<c:if test="${log.isEfectSendElec=='影响'}">
<input type="checkbox" name="isEfectSendElecopen" id="isEfectSendElec" lay-skin="switch" lay-filter="switchText"
onclick=""
lay-text="是|否"
checked="checked">
</c:if>
</div>

这个是我写的js代码

form.on('switch', function(data){
var elem = data.elem;
var swithcData = data;
var id = data.value;// 获取要修改的ID
var state = this.checked ? '影响' : '不影响';// 当前状态值
if (state ==='影响'){

layer.msg('数据异常，操作失败！1111');
}

各位大佬，在页面上选择了是input框才可以输入，没选就不给输入，想问一下怎么写呢？我是小白，谢谢各位了
