javascript - undefined 不是 javascript 加载时的函数错误

Question

在过去的 3 个小时里，我一直在尝试调试这个问题，现在拉扯我的头发。在我的网站中，当我加载时，我得到一个未定义的不是函数。我一直在查看语法，似乎没有任何问题。这是我网站的链接。如果您检查控制台，那么它会在第一次加载时出错。任何想法？

Your plugin "Lazy Load" does not terminate with a semi colon, and as such cannot be combined into a single file with "malihu jquery custom scrollbars".

As the second plugin starts with (, the javascript engine will interpret that as a call to a function that it expects to be returned from the previous function call.

Add a ; at the end of the Lazy Load file.

Roughly, the code

/*
 * Lazy Load - jQuery plugin for lazy loading images
 */

(function(a,b,c,d){ .... })(jQuery,window,document)

/* 
== malihu jquery custom scrollbars plugin == 
*/
(function($){ ...})(jQuery);

is interpreted as

anonymousFunction(jQuery, window, document)(function($) { ... })
                                           ^ anonymous function returns undefined
                                             but a function was expected
