问题
I have created a Greasemonkey script for a website. What the script does is adding a div at the end of the page.
document.body.insertBefore(myDiv, document.body.firstChild);
But now the site adds an iframe for google-ads, as a result my div appears in the iframe too, which is not what I want.
How can I stop the script affecting iframes?
回答1:
Greasemonkey now supports the @noframes directive (long supported by Tampermonkey and Scriptish).
Use that for a cleaner way to block operation in iframes.
Unfortunately, npdoty's answer will now trigger a warning in Firefox's browser console:
Warning: use of return outside of functions is deprecated and may cause failures in future versions of Greasemonkey.
回答2:
I put this at the top of my scripts to avoid running on frames or iframes:
if (window.top != window.self) //don't run on frames or iframes
return;
