Answer 1

If the problem is that you are not getting the browser's download dialog for the PDF, then the solution is to do it this way:

First, redirect the browser (using window.location as the other answers say) to navigate to a special controller action in your application, e.g. with this url: http://your.application.com/download/pdf/filename.pdf.

Implement the action referenced in the URL like this:

public function actionPdf() {
    header('Content-Type: application/pdf');
    header('Content-Disposition: attachment; filename="filename.pdf";');
    header('Content-Length: '.filesize('path/to/pdf'));
    readfile('path/to/pdf');
    Yii::app()->end();
}

This will cause the browser to download the file.

You need to save the PDF to somewhere on your server and then issue window.location = '/url/to/pdf-you-just-saved.pdf'; from your javascript. The users browser will then prompt them to download the PDF file.
