Including JS file in View In YII

Question

I want to load the JS file in view to avoid heavy-loading of my application. I am using this JS file for CgrdView in view. SO i tried this:

Yii::app()->clientScript->registerScriptFile(
Yii::app()->baseUrl.'/assets/9d419b82/jquery.ba-bbq.js?v=1.0.127'
);

in My view header. But i am getting the error:Uncaught ReferenceError: jQuery is not defined As stated, i want to load jquery.ba-bbq.js file in view for CgriView, but i am not able to load that. Instead, i use following, but dont know is the efficient way to load or not.

<script src="/assets/9d419b82/jquery.ba-bbq.js?v=1.0.127" type="text/javascript"></script>

And is working when i load that in layouts, but this is not the efficient way.

FYI: I am working with cgridview search-box to post the search-box entry to my controller.

The bbq script is available as a core script and registering it will also load jquery.js. So to use bbq you simply need to do this:

Yii::app()->clientScript->registerCoreScript('bbq');

The assets folder is dynamic in nature, and it is used to store scripts, css, images in a web-accessible directory. It is automatically populated by the various Yii widgets, and also when you call registerCoreScript. Because of these reasons and more you shouldn't be relying on the assets folder to include js, css, images, but instead let the framework include it for you.

I couldn't find a list of the core packages in the docs, but it can be seen in the source file: framework/web/js/packages.php.

Incase you want this in a view with a CGridView, then let me tell you that CGridView loads this script automatically, and you don't have to register it again.
