Why doesn’t document.addEventListener(‘load’, function) work in a greasemonkey script?

Code inside DOMContentLoaded event not working
It’s most likely because the DOMContentLoaded event was already fired at this point. The best practice in general is to check for document.readyState to determine whether or not you need to listen for that event at all. if (document.readyState !== ‘loading’) { console.log(‘document is already ready, just execute code here’); myInitCode(); } else { document.addEventListener(‘DOMContentLoaded’, … Read more
addEventListener vs onclick
Both are correct, but none of them are “best” per se, and there may be a reason the developer chose to use both approaches. Event Listeners (addEventListener and IE’s attachEvent) Earlier versions of Internet Explorer implement JavaScript differently from pretty much every other browser. With versions less than 9, you use the attachEvent[doc] method, like … Read more
Does AJAX loaded content get a “document.ready”?
To answer your question: No, document.ready will not fire again once a ajax request is completed.

how to listen for clicks in Java (JFreeChart) using events?
You can use addChartMouseListener() to add a ChartMouseListener to your ChartPanel.

Variable in JavaScript callback functions always gets last value in loop? [duplicate]
The problem is that you are ‘closing’ over the same variable. var does not declare a variable1. It simply annotates a ‘stop look-up’ for an identifier within a given execution context. Please see Javascript Closures “FAQ Notes” for all the nice details. The sections on ‘execution context’ and ‘scope chain’ are most interesting. The common … Read more
addEventListener on NodeList [duplicate]
There is no way to do it without looping through every element. You could, of course, write a function to do it for you. function addEventListenerList(list, event, fn) { for (var i = 0, len = list.length; i < len; i++) { list[i].addEventListener(event, fn, false); } } var ar_coins = document.getElementsByClassName(‘coins’); addEventListenerList(ar_coins, ‘dragstart’, handleDragStart); or … Read more

addEventListener on a querySelectorAll() with classList [duplicate]
There are some dissimilarities between the code and the link you have provided. There is no function doit() in there. You have attached addEvenListener to the NodeList in cbox.addEventListener(“click”,….., you have to loop through the list and attach the event to the current element: Try the following: const cbox = document.querySelectorAll(“.box”); for (let i = … Read more
