Setting your variables in a key=>value array and using CJSON::encode works really well. You can access all your variables via the object created by jQuery's parseJSON. For example:

$myVarList = array(
 'nameOne'=>$valueFromAnotherVar,
 'nameTwo'=>$object->coolValue,
 'nameThree'=>$cat->hoursSleptToday()
);

Yii::app()->clientScript->registerScript("myVarList",
    'myVarList = jQuery.parseJSON('.CJSON::encode($myVarList).');'

You can then access the values from the global var.

myVarList.nameOne || myVarList.nameTwo || myVarList.nameThree
