External Links in New Window with Message box

External links to the websites should alway open in new window. Else users will leave your website and may not return back.

Also its good to display a message box stating that they are leaving the website. Use the following method to achive this.

1. Create new file external.js
2. Put the following code in there.

$(function() {
$('a[@href^=http]').not('[@href*=yourdomain.com]')
.addClass('external-link')
.click(function() {
window.open(this.href, '_blank');
return false;
});
});


In above code replace yourdomain.com with your website domain.

3. Put the following code in your theme's template.php

drupal_add_js('misc/external.js', 'theme');


4. Upload the external.js in your drupal 5.0 's misc folder.

5. Modify your theme's .css file to include the following class
(optional)
.external-link {
padding-left: 18px;
background-image: ("/files/images/extlink.png");
}

A variation to above code... to display message box on clicking of external link add the following code.

$(function() {
$('a[@href^=http]').not('[@href*=yourdomain.com]')
.addClass('external-link')
.click(function() {
confirmed = window.confirm("You are leaving this website, Click OK to continue. Click Cancel to stop.");
if (confirmed){
window.open(this.href, '_blank');
return false;
}
else
{
return false;
}
});
});
