有问题的js
<script type="text/javascript"> layui.use('element', function(){ var element = layui.element; //导航的hover效果、二级菜单等功能，需要依赖element模块 //监听导航点击 element.on('nav(demo)', function(elem){ console.log(elem.text()); layui.layer.msg(elem.text()); }); }); </script>
这样写，msg 会出现问题。不能实现功能。用msg的功能需要，监听layer,然后拿到layer对象才能调用msg的功能
layui，layer学习过程中...
