Answer 1

I found this way:

1. Check the function registerScriptFile() in CClientScript.php , if the param htmlOptions does not exist, replace 2 files bellow in your source from https://github.com/yiisoft/yii

   • CClientScript.php

   • CHtml.php

2. Comment line 'defer'=>1 of function renderAttributes() in file CHtml.php
3. Add this line: Yii::app()->clientScript->registerScriptFile(Yii::app()->get‌​BaseUrl().'/js/jquer‌​y.js', CClientScript::POS_HEAD, array('defer'=> ''));

You can provide the option such as

$this->registerJsFile('https://apis.google.com/js/platform.js?onload=renderButton',['position' => View::POS_END, 'async'=>true, 'defer'=>true]);

To add interanl js

  $this->registerJsFile(Yii::$app->view->theme->baseUrl .'/your_js_path',['position' => View::POS_END, 'async'=>true, 'defer'=>true]);
