Attach the functions via addEventListener to the button element when you create it. If you define the function above the function you create the button in, it should work fine. It looks something like this:
// ==UserScript== // @name Button click demo // @version 1 // @author LWChris // @include https://www.w3schools.com/jsref/met_element_addeventlistener.asp // @grant none // ==/UserScript== function theButtonWasClicked() { alert("Hello World!"); } function addTheButton() { var btn = document.createElement("button"); var content = document.createTextNode("Say hello"); btn.appendChild(content); btn.addEventListener("click", theButtonWasClicked); document.getElementById("main").appendChild(btn); } addTheButton(); Chris Am 08.02.2020 um 00:25 schrieb Peter Blake:
I'm looking for help with a script I'm writing <https://pastebin.com/jv5qZ9uj> to hide unwanted search results on Scribd using GM 4.9 and Firefox 72. This old script from 2012 <https://userscripts-mirror.org/scripts/review/127536> seemed to do a similar job on Craigslist, so I set about updating it re-tooling it for my needs. However, the buttons I add to the page can't see the functions in the script that need to trigger in response to a click (log shows "ReferenceError: hideListing is not defined"). I did some poking around and thought that something along the lines of: | Components.utils.exportFunction(hideListing,unsafeWindow,{defineAs:"hideListing"}); | might solve my problem, but to no avail. My programming skills are very rusty, so I'd appreciate any help or insight you can offer.
