  });
});

<select id="x">
  <option selected>A</option>
  <option>B</option>
  <option>C</option>
</select>

In the below code there is no effect when I click on the options already selected options. for example a is selected then i click a is no effect.

$(document).ready(function() {
  $("#x").on("option", "click", function() {
    alert("Haha");
  });
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

"click selection box->drop menu->click selected option->trigger event"

First of all do not use alert(), it prompts for an extra click you really don't need to waste your time on. Use console.log().

The following demo:

  • Delegates the click event to select#x:

$('#x').on('click',...

  • Once clicked, it will trigger a focus event on every even click✱:

✱ if (cnt % 2 === 0) { $(this).trigger('focus');}

  • select#x is also delegated to the focus event and will call optionTrigger():

$('#x').on('focus', optionTrigger);

  • function optionTrigger() will log the selected <option> index and text:

✱ if (cnt < 2) {...

...$(this).trigger('blur'); }

var idx = $(this)[0].selectedIndex;

var txt = $(this).find('option').eq(idx).text();

Demo

var cnt = 1;

$("#x").on("click", function(e) {
  if (cnt % 2 === 0) {
    $(this).trigger('focus');
  }
  cnt++;
});

$('#x').on('focus', optionTrigger);

function optionTrigger(e) {
  if (cnt < 2) {
    $(this).trigger('blur');
  } else {
    var idx = $(this)[0].selectedIndex;
    var txt = $(this).find('option').eq(idx).text();
    console.log(idx + ': ' + txt);
  }
}
<select id="x">
  <option>A</option>
  <option>B</option>
  <option>C</option>
</select>

Do you need to execute your code while clicking on Dropdown???

If Yes, here is the code for you

If not please leave a comment along with your requirements.

$(document).ready(function() {
  $("#x").off().on('click',function() {
    alert("Haha");
  });
});

Have you tried bind with select e.g.:

$('#x').bind('click', function(){
    console.log('Clicked') 
 });

If this doesn't work do tell. Thanks Hope this helps.
