Open button link in new tab (pre-made page, URL not in <>)

[BrandonJ]

Hi there,

I know the obvious ad: target="_blank" after a url, but its a pre-made page that I am editing and you just ad the url onto a blank link with no <> and the page grabs it and inserts it where need be.

Later in the page is this code for a button:

<button id="surveyAgree" data-tracking-suffix="<?php echo $buttonClickTrackingSuffix; ?>" class="stepButton yesBtn" onclick="<?php echo $onclick; ?>">I AGREE!</button>

Is there somewhere there that I can ad something to make it open in a new tab, or does the css have to be edited?

OR could I just replace the script that is grabbing the URL with the actual URL?

OR is there something I can add to the URL? as I mentioned it's just on a line by itself, not inside <> so it is just like:

http://example.com

Thanks for having a look!

Much appreciated
