importing external javascript to google apps script [duplicate]

I am trying to use Trello from a Google Spreadsheet (Google Docs) and am not sure how to import/reference/link the javascript files required to use their library. My only other option is using their REST API directly (fine, but I'd rather use their js helper classes).

This is what Trello needs us to use:

 <script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
 <script src="https://api.trello.com/1/client.js?key=substitutewithyourapplicationkey"</script>

How would I import/include these in a Google Apps Script?

THANKS!!!

Solution 1:

Based on the answer here by Cameron Roberts, you can use the eval() function on the appscript UrlFetchApp function.

eval(UrlFetchApp.fetch('http://path.to/external/javascript.js').getContentText());

Solution 2:

you actually can . In the script project create another new file and simply just paste the JavaScript library copying from the source and save it then start referencing it from other file. It is that simple.

Or you can create another project with the .js lib and publish it and reference that script from the caller project, I wont do that unless that needs to be shared in multiple projects.
