 </div>
</form>

<script>
 layui.use(['form'], function(){
  var form = layui.form
   ,layer = layui.layer
  //监听指定开关
  form.on('switch(switchTest)', function(data){
   if(this.checked){
    layer.msg('开关checked：'+ (this.checked ? 'true' : 'false'), {
     offset: '6px'
    });
    layer.tips('温馨提示：请注意开关状态的文字可以随意定义，而不仅 仅是ON|OFF', data.othis)
   }else{
    layer.msg('开关： 关掉了', {
     offset: '6px'
    });
