有問題的js
<script type="text/javascript"> layui.use('element', function(){ var element = layui.element; //導航的hover效果、二級菜單等功能，需要依賴element模塊 //監聽導航點擊 element.on('nav(demo)', function(elem){ console.log(elem.text()); layui.layer.msg(elem.text()); }); }); </script>
這樣寫，msg 會出現問題。不能實現功能。用msg的功能需要，監聽layer,然后拿到layer對象才能調用msg的功能
layui，layer學習過程中...
