Open http://jsfiddle.net/cvrebert/Lxwc1eah/show/ 2. Open the console 3. Click the webpage's checkbox 4. Observe the console output In Chrome, Safari, and IE11, the output is: change click In Firefox only, the output is: click change The majority position is that, when the user clicks an <input type="checkbox">, the `change` event gets fired before the `click` event. Firefox does the reverse. The spec currently agrees with Firefox but disagrees with the majority. Here are the relevant portions of the spec: https://html.spec.whatwg.org/multipage/interaction.html#run-authentic-click-activation-steps When a user agent is to [[[run authentic click activation steps]]] for a given event event, it must follow these steps: [...] 6. Dispatch event (the required `click` event) at target. If there is an element e and the `click` event is not canceled, [[[run post-click activation steps]]] on element e. https://html.spec.whatwg.org/multipage/interaction.html#run-post-click-activation-steps When a user agent is to [[[run post-click activation steps]]] on an element, it must run the [[[activation behaviour]]] defined for that element, if any. https://html.spec.whatwg.org/multipage/forms.html#checkbox-state-(type=checkbox):activation-behaviour 4.10.5.1.16 Checkbox state (type=checkbox) The [[[activation behaviour]]] is to fire a simple event that bubbles named `input` at the element and then fire a simple event that bubbles named `change` at the element. 124505 1 w3bugs 2016-01-03 07:57:09 +0000 Safari 9.0.2's behavior is unchanged. MS Edge behaves the same as IE11. Chrome 47 has apparently switched to behaving like Firefox. 124506 2 w3bugs 2016-01-03 07:57:55 +0000 Bloody dropdowns.. 124507 3 w3bugs 2016-01-03 08:08:19 +0000 And `click` comes first in Opera 12. 124613 4 w3bugs 2016-01-18 09:57:18 +0000 Filed MS Edge bug: https://connect.microsoft.com/IE/feedback/details/2255779 124614 5 w3bugs 2016-01-18 10:09:47 +0000 Deeming this to now be a bug in the remaining browsers rather than the spec itself, since 2 browsers now match the spec and Safari appears open to changing to match the spec (hopefully Edge will respond positively too). (And the spec's behavior is certainly more logical than the alternative behavior, so now that compat is less of a factor, there's no reason to want the spec to change.)
