Efficiently add a click event handler to many elements in jQuery

When you need to add a click event handler to 50+ elements in jQuery, this might slow down the browser.

You can simply register an event at the root of the DOM instead. This waits for events to bubble up and checks whether the triggering element matches the selector:

$(document).on('click', '.dialog_link', function(event) { // Open dialog });

Fun fact: Angular 2.0 will provide native syntax for event handlers that are registered on the document body,
