js部分：;(function($){ //聲明LightBox類構造函數
var LightBox = function(){
alert('msg');
};
LightBox.prototype = {
};
Window["LightBox"] = LightBox;
})(jQuery);html部分：<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" type="text/css" href="css/reset.css">
<link rel="stylesheet" type="text/css" href="css/lightbox.css"> </head><body>
<script type="text/javascript" src="js/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="js/lightbox.js"></script>
<script type="text/javascript">
$(function(){ var LightBox = new LightBox();
}); </script></body></html>正常應該alert彈出框吧，但控制臺如下錯誤是為什么？
js創建自定義類時報錯
