Implement tag cloud is easy in Drupal. You can find the module called Tagadelic in the my previous post.
Drupal 7 – Create a Tag Cloud with Tagadelic
But the term path inside the tag cloud is always fixed as default which is taxonomy/term/[tid]. I tried to override it by the Entity Path module but no luck.

The following theme function theme_tagadelic_weighted() determines the term path in Tagadelic.

Drupal 7 – Add Javascript files on specific paths by custom module
In the past, i always added js files on theme level. This is not a good approach because the aggregated theme js will be quite large and it is loaded on every pages even js code is not used.
So this time i try to add the js on specific path only when it is needed. This is done by creating a custom module. Let’s name the custom module eureka_js.
1. Inside the eureka_js module folder, we have the following files.
- js/eureka.js

- eureka_js.module
