Is it possible to add eventListener with regex?
Something like this:
document.addEventListener(""+/\d+/+"", function (data) {
// ...
});

1Can you explain your purpose more? – Aitor Aznar Álvarez Nov 25 '15 at 11:51

Sure. I want to send event.initEvent("someNumber") from the page and listen to that event on content script for chrome extension. I have "someNumber" only as string in window variable – Dusty Nov 25 '15 at 11:55

If you have delimited event names, you can put them into the addEventListener. – Aitor Aznar Álvarez Nov 25 '15 at 12:15

How about `if(regex.test(eventName)) { ... document.addEventListener(eventName, ... ) ... }` ? – vrintle Oct 16 '20 at 08:15

It's impossible to attach an event listener to events by mask. You can take a list of events, here, for example and listen to all of them in a cycle to attach our handler to them.

Thank you for the answer. I don't understand why in http://krasimirtsonev.com/blog/article/Send-message-from-web-page-to-chrome-extensions-background-script you can listen to "hello" and you can't use regex? – Dusty Nov 25 '15 at 12:13

@Dusty This is an interface for Chrome extensions: https://developer.chrome.com/extensions/runtime – Vladislav Rastrusny Nov 25 '15 at 12:15
