How to add JavaScript to you view files using the Yii Framework

Add the JavaScript code as below to your view

	$js = Yii::app()->getClientScript();
 
	$js->registerScript(
 
	'my-javascript-id',
 
	'var value = "Hello World";
 
	alert(value);',
 
	CClientScript::POS_END );

Yii’s CClientScript is used to place JavaScript to your views.

The arguments of register script are as follows:

• The first argument uniquely identifies your script
• The second argument contains your actual JavaScript
• The third argument sets the position where the JavaScript should be placed. In the example above the CClientScript::POS_END specifies that the script will be placed before the closing </body> tag.
