How can I get this value in javascript?

I'm working on a opera extension that will search for a specific element on the current page once clicked. But I'm lost and I don't know what to do since I'm a very beginner in html/js stuffs.

The value that I am trying to extract from the page source is:

<script type="text/javascript">        

      var DEFAULT_URL = '/test/files/db9594e7e810cccdceb2e4faae6339a8.pdf';        

</script>

What should I do to extract this kind of attribute value from a pdf viewer link's page source? Any help would be appreciated, thank you in advance.

There must be a way to just access window variables from an opera extension... Can't you just access window.DEFAULT_URL since that variable has been set?

As an alternative, you should be able to parse it out manually. The code below will give you all the script tags:

document.querySelectorAll("script")

If you want to get the content of the first script tag, you should be able to do so with:

document.querySelectorAll("script")[0].innerHTML

Once you've got that, you should be able to parse and extract the URL that you need from it.

If you are on the pdf page, you can extract the path from url using

var url = winfow.location.href;

This is what I understood from your question. Otherwise, please elaborate.

If you are extracting from another file in the directory then try var DEFAULT_URL = require('/test/files/db9594e7e810cccdceb2e4faae6339a8.pdf')
