是否可以阻止在某些站点页面上加载.js文件来停止浏览器错误？

Question

I am getting a heavy load of errors because a Jquery .js file I have embedded in the Joomla index.php page. These errors are just browser errors but if I do any scrolling they just pile up.

The specific error says this:

Uncaught TypeError: Cannot read property 'top' of null js-snippets.min.js:11
(anonymous function) js-snippets.min.js:11
f.event.dispatch js-snippets.min.js:4
h.handle.i js-snippets.min.js:4 

The page it is supposed to work on is fine and does not see this error.

I guess I could put the .js file reference in each html page that I need it for but I hate doing that. Isn't it better for the file to be in one single place?

In any event if I could prevent the .js file from loading on page(s) it would be ideal.

Here is a link to the site in questions.

You could write a small script to test whether your js is needed and inject it only if needed. Or better: adapt the .js so it tests by itself whether it is needed.
