How do I fix this? Please bear in mind I can't edit the external Javascript file as it's third party.
我该如何解决?请记住,我无法编辑外部 Javascript 文件,因为它是第三方的。

Use the following statement in a JS file.
在 JS 文件中使用以下语句。
jQuery(document).ready(function($){
// jQuery code is in here
});
After declaring the above statement you will be able to use $ sign.
声明上述语句后,您将能够使用 $ 符号。

I think the issue was because the external javascript was loaded first before the jquery was loaded. To solve this use requirejs, follow this link for the usage http://requirejs.org/docs/api.html
我认为问题是因为在加载 jquery 之前首先加载了外部 javascript。要解决这个使用requirejs,按照这个链接使用http://requirejs.org/docs/api.html
