I am working on an AngularJs project. I have a service which sets and removes events on some buttons. This service is utilized by another service which I do not want to interact directly with the buttons. However I would like a button click event to be filtered up through the first service and handled in the second one. Since I don't want the second service to be aware of the buttons, I figure I will need to create a custom event in the first service.

问题 Is it possible in JavaScript to listen for a change of attribute value? For example: var element=document.querySelector('…'); element.addEventListener( ? ,doit,false); element.setAttribute('something','whatever'); function doit() { } I would like to respond to any change in the something attribute.

问题 I am creating an event, so use the DOM Event constructor: new Event(\'change\'); This works fine in modern browsers, however in Internet Explorer 9, 10 & 11, it fails with: Object doesn\'t support this action How can I fix Internet Explorer (ideally via a polyfill)?
