You're trying to access the meta tags in a remote page. You'll want to use PHP for that, since Javascript won't be able to access the details in that page.

Luckily, there's get_meta_tags function. You can do something like:

$url = 'http://shodhganga.inflibnet.ac.in/handle/10603/2769';
$tags = get_meta_tags($url);
print_r($tags);

Example:

echo $tags['generator'].'<br>';
echo $tags['dcterms_spatial'].'<br>';
echo $tags['dc_creator'];

Output:

DSpace 1.8.2
Physical education
Balasubramanian, K

And then, you can pass the values to Javascript and use it however you like.

Hope this helps!
