How to Detect Clicked Event Handler on Select2 Element in Jquery?

Question

I tried to detect if the clicked element is select2 and perform additional action as required not just opening dropdown list. But it is not successful as I clicked on select2 element nothing happened.

 $(document).ready(function() { $('select').select2(); $('body').on('click', function(e) { if ($(this).data('select2')) { console.log('select2 element was just clicked'); } else { console.log('you are not clicking on select2'); } }); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/3.5.4/select2.js"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/select2/3.5.4/select2.css" /> <select style="width:300px" id="select"> <optgroup label="Alaskan/Hawaiian Time Zone"> <option value="AK">Alaska</option> <option value="HI">Hawaii</option> </optgroup> <optgroup label="Pacific Time Zone"> <option value="CA">California</option> <option value="NV">Nevada</option> <option value="OR">Oregon</option> <option value="WA">Washington</option> </optgroup> <optgroup label="Mountain Time Zone"> <option value="AZ">Arizona</option> <option value="CO">Colorado</option> <option value="ID">Idaho</option> <option value="MT">Montana</option> <option value="NE">Nebraska</option> <option value="NM">New Mexico</option> <option value="ND">North Dakota</option> <option value="UT">Utah</option> <option value="WY">Wyoming</option> </optgroup> <optgroup label="Central Time Zone"> <option value="AL">Alabama</option> <option value="AR">Arkansas</option> <option value="IL">Illinois</option> <option value="IA">Iowa</option> <option value="KS">Kansas</option> <option value="KY">Kentucky</option> <option value="LA">Louisiana</option> <option value="MN">Minnesota</option> <option value="MS">Mississippi</option> <option value="MO">Missouri</option> <option value="OK">Oklahoma</option> <option value="SD">South Dakota</option> <option value="TX">Texas</option> <option value="TN">Tennessee</option> <option value="WI">Wisconsin</option> </optgroup> <optgroup label="Eastern Time Zone"> <option value="CT">Connecticut</option> <option value="DE">Delaware</option> <option value="FL">Florida</option> <option value="GA">Georgia</option> <option value="IN">Indiana</option> <option value="ME">Maine</option> <option value="MD">Maryland</option> <option value="MA">Massachusetts</option> <option value="MI">Michigan</option> <option value="NH">New Hampshire</option> <option value="NJ">New Jersey</option> <option value="NY">New York</option> <option value="NC">North Carolina</option> <option value="OH">Ohio</option> <option value="PA">Pennsylvania</option> <option value="RI">Rhode Island</option> <option value="SC">South Carolina</option> <option value="VT">Vermont</option> <option value="VA">Virginia</option> <option value="WV">West Virginia</option> </optgroup> </select> 

I don't know why select2 does not receive clicked event. Is there any workaround solution archive this because I need to do more action when select2 was clicked? Thanks so much.

How about something like this? here's another example: https://jsfiddle.net/f8q2by55/ http://jsfiddle.net/6jaodjzq/

as stated in this answer: Attach click-event to element in .select2-result

Because Select2 lib prevents any click events on popover list you can't bind events to .info directly. But you can redefine onSelect method and place there any code you want.

 $(document).ready(function() { let selector = $('#select').select2() selector.onSelect = (function(fn) { return function(data, options) { console.log('selected'); } })(selector.onSelect); })
