VistasFind what happens when you click an HTML button
For example, you have this script that adds an event listener to a button like this:
document.getElementById("myBtn").addEventListener("click", function() {
document.getElementById("demo").innerHTML = "Hello World";
});
How would I see that code in a website, so I can execute the code from the console?

You want to trigger the event from the console. But that is not possible. However, you can call an external function in the second parameter of the EventListener. This function is then in the global scope. You can then trigger the action in the console with the function name that would otherwise be triggered via the click.
makeAction();
document.getElementById("myBtn").addEventListener("click", function() {
makeAction();
});
function makeAction() {
console.log('triggered')
document.getElementById("demo").innerHTML = "Hello World";
}<button id="myBtn">click</buton>
<div id="demo"></div>

On Chrome, you can open developer tools, select the element, then select the 'Event Listeners' tab:
Which will show you the event listeners bound to the element:
