Can all Javascript events be monitored?
I am wondering whether there is an event that gets triggered after the DOM has been modified by an AJAX request.
Can all Javascript events be monitored?
I am wondering whether there is an event that gets triggered after the DOM has been modified by an AJAX request.
Discovering event information with tools like Firebug or Web Inspector is possible by utilizing the monitorEvents command:
monitorEvents(myDomElem);
This command will display all events triggered by myDomElem in the console. To cease monitoring, use unmonitorEvents.
If you require access to events post-DOM manipulation, consult Mutation Events.
Edit:
In terms of capturing all onreadystatechange events from each XMLHttpRequest instance, one potential solution involves overriding the native XMLHttpRequest object with a custom implementation. Here's an example:
(function() { // Overriding XMLHttpRequest
var oldXHR = window.XMLHttpRequest;
function newXHR() {
var realXHR = new oldXHR();
realXHR.addEventListener("readystatechange", function() {
console.log("an ajax request was made")
}, false);
return realXHR;
}
window.XMLHttpRequest = newXHR;
})();
Nevertheless, it's important to note that this approach is considered quite unconventional and may not be recommended.
If you want to build on Xavi's suggestion about using monitorEvents(myDomElem), a way to exclude mouse events would be to use
unmonitorEvents(myDomElem, 'mouse')For more information on utilizing Chrome's monitor events feature, check out this helpful article: http://www.example.com/chrome-developer-tools-monitoring
