javascript - Trigger event on parent originating, bubbling up from child -


if have <div class="timely"></div> containing table, in table <th class="prev"><i>previous</i></th>...chrome dev tools there event listener on <th>, firefox dev tools points out not on <th>, parent .timely, chrome points out when viewing in handler event.

what trying replicate happens on click, happen on keyup. doesn't seem simple as, in jquery:

$('.timely th').each(function(){     $(this).on('keyup', function(){         $(this).trigger('click');     }); });

because event handler on .timely , listening event bubbled when executing code.

how can replicate click event on keyup of .timely context of bubbling <th>?

first, note there's no reason each loop (unless you're doing else in haven't shown). remember jquery set-based, $("selector").on(...) sets handler on elements in set.

re question: accept event argument , use target property element on trigger:

$('.timely th').on('keyup', function(e) {     $(e.target).trigger('click'); });

or if want handle on .timely instead of on th in .timely, change selector , use delegating form (assuming want th elements):

$('.timely').on('keyup', 'th', function(e) {     $(e.target).trigger('click'); });

it's tricky keyup on th element, of course; way coming mind put input element in th keyup bubbles:

$('.timely th').on('keyup', function(e) {      console.log("keyup");      $(e.target).trigger('click');  });  $('.timely th').on('click', function(e) {      console.log('click');  });
<div class="timely">    <table>      <tbody>        <tr>          <th>            <input type="text">          </th>        </tr>      </tbody>    </table>  </div>  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

you haven't said why want trigger click on keyup, if it's run click event handler, don't recommend doing that. instead, use same function both keyup , click handler. can hook multiple events space-delimiting them in .on (.on("click keyup", ...)), or use named function , refer hook click , keyup handlers.

chrome dev tools there event listener on <th>, firefox dev tools points out not on <th>, parent .timely

if don't want see handlers attached ancestors, untick ancestors box in event listeners tab:

but note in example code, handler on th, not ancestor .timely element.
