// surround everything with the '/' to specify regex matching
// regex means http or https
// including any subdomain, including the domain wikia.com by itself. 
// subdomain can be any length with any characters, with a dot at the end. subdomain optional
// * in a regex match is not a typical wildcard. I need .* because the * in regex means that any character (.) appears 0 or more times.
// so in regex, 'https://example.com/xx-xx/Asset/*' means '/' appears 0 or more times
// outside of regex matching, like in greasemonkey's case, * means wildcard
// so 'https://example.com/xx-xx/Asset/*' means anything can appear after '/'
// at .com top level domain
// with anything proceeding afterwards

// So your https://example.com/xx-xx/Asset/* pattern would become:
// @include  /^https:\/\/example\.com\/[a-z]{2}\-[a-z]{2}\/Asset\/.*$/

// you can use either of these includes
// include     http*.wikia.com/*
// include     /^https?://(.*\.)?wikia\.com/.*$/

// <button id="ContentWarningApprove" class="approve">I understand and I wish to continue</button>

// call script after the page loads
// unlike blogspot, wikia needs time to load because the buttons popup afterwards

window.addEventListener('load', function() {
    // your code here
	
	//document.getElementsByClassName('approve').click();
	// this does not work
	
	//document.getElementsByClassName('approve')[0].click();
	// this works. however, ID is preferred over class
	// for some reason getElementsByClassName doesn't work sometimes. maybe ajax is still trying to load?
	
	
	document.getElementById('ContentWarningApprove').click();
	// this works
	
}, false);
