Greasemonkey/ Tampermonkey @match for a page with parameters
@match only works on the protocol/scheme, host, and pathname of a URL.
To trigger off the query parameters, you can either use @include or use @match and also test the URL yourself.
Note that the @match approach performs faster.
With @include, you can use a regex syntax. See, also Include and exclude rules.
In this case, use either:
...// @include /^https?://example\.com/page\.php*key1=value1*/// ==/UserScript==**Or:**
...// @match *://example.com/page.php*// ==/UserScript==if (/\bkey1=value1\b/.test (location.search) ) { // DO YOUR STUFF HERE.}
According to the documentation for @match, it doesn't appear that query string parameters are something the Greasemonkey engine will match on:
