I want to see the alert message:window with the alert message or open a new window(pop-up)with a link

I have a distinct feeling you're trying to mix Javascript's "alert"
function with PHP which is why the JText works fine and why you get an
undefined function error from PHP when you try to feed it Javascript.

I have a distinct feeling you're doing something for the wrong
reasons. Can you elaborate on what you're trying to achieve and why
you're trying to achieve it using this method? Some context might help
provide solutions (and a larger chunk of source code).

Thanks for your answer,
I'm trying to show the alert message or to open a new window(redirecting to the registration page).
I don't understand how to do it.
My essential object is to open a new window(pop-up)
Please help me to do this.

Best regards

Hello, 

 You are trying to alert javascript box into PHP , thats wrong dude , If you want alert message eighter you call component url through ajax and get response and alert it like this.

I am showing you 2 methods.

javascript code :, I am using Jquery POST Ajax method, whatever you will send through component url will be alret into template page.

<script>

function call_server_url(){

   $.post("COMPONENT URL ",{PARAMETER},function(message){

    alert(message);

})

}

</script >

2.Second Method, you try this.

<?php 

function Your_Function_Name(){

   echo '<script>alert("'._JText("WHATEVER YOUR MESSAGE HERE").'")</script>';

}

Normally you would set a redirect in the controller and in the
redirect set the message to be displayed to the user. There is no
point putting up a popup window where you intend to redirect them
after they've downloaded half the page, just redirect the user.

Check out JController::setRedirect or JApplication::redirect for more
details. The pattern is used in unauthorised situations with a
redirect back for login however in your case you're just going to
redirect to a sign up page.

I tried to do so:
......
else {
            jimport( 'joomla.application.component.controller' );

            $this->Redirect('index.php?option=com_user&view=login', 'Veuillez vous identifier','notice');
            return $this;}
But i saw again this error:
Fatal error: Call to undefined method ElementVideo::Redirect() in C:\wamp\www\Societe\administrator\components\com_zoo\elements\video\video.php on line 124

what shall i do to solve this problem?

You're in a subclass of something in Zoo it seems, I'd suggest asking
the zoo people what the best course of action would be.
