How to push the ids of selected option of dropdowns into an array using jquery?

Question

Hi I am new to jquery actually I had an dropdown in my html where I will get the options from database using ajax here I am retrieving the id and option from database but showing only the options in the dropdown

The code for dropdown which I done so far in html is

<div id="container" class=""></div>
<button id="seedoc" style="float: right; margin-right: 10px;" onclick="addOne();"></button>
function addOne() {
getEmails();
$('#container').append(
<div class='form-group' style='display:flex'>
<select class='drop form-control'  name='option' id='option'>
<option value='' disabled selected>Select your option</option>
</select>
                <button class="btn btn-primary shrBtn" style="float:left;" onclick="send()">Send</button>

</div>

the json response I get from db.php is

users:
[ "<p style='margin:0px;display:none;'data-id='755'>amilham</p>",
"<p style='margin:0px;display:none;'data-id='706'>a_sarabi</p>"]

and in dropdown I am getting amilham,a_sarabi so here in the dropdown if I select amilham I need to get the data-id ie 755 into an array and also in the another dropdown if I select a_sarabi I need to get 706 into array using jquery

can anyone help me please

so far I tried like this but not getting

function send()
{
    var uids = [];
    \$('.drop').change(function(){
   \$(this).find('option:selected').each(function(){
       uids.push(\$(this).attr('data-id') );
    });
   });

I need all the ids of selected options in all the dropdowns I add using jquery Populating options from db into dropdown

function getEmails(){
        
    
    \$.ajax({
        url :'propage.php',
        type : 'POST',
        dataType : 'json',
        data : '&userId='+\$('#hdn_userid').val()+'&action=getEmails',
        success : function(res){
            res.users.forEach(function(option) {
            \$('.drop').append('<option>' + option + '</option>');
        });
      },
    });
  }

I have created a demo example (by adding your json response data form db.php) of what you are saying. You can store the data-id on clicking send button.

Run snippet below and select the option and click send to see the array uids will have the data-id of the selected option.

 //Store in array() var uids = []; //Select option function $(document).on("change", ".drop", function() { //Find option selected var data = $(this).find("option:selected").attr('data-id') //Push selected data-id uids.push(data) //Enable button on selection $('#seedoc').prop('disabled', false) }) //Send function send() { console.log(uids) } //response var res = { "users": ["<p style='margin:0px;display:none;'data-id='755'>amilham</p>", "<p style='margin:0px;display:none;'data-id='706'>a_sarabi</p>" ] } function getEmails() { res.users.forEach(function(option) { $('.drop').append('<option data-id=' + $(option).attr('data-id') + '>' + option + '</option>'); }); } function addOne() { $('#container').append("<div class='form-group' style='display:flex'><select class='drop form-control' name='option' id='option'> <option value='' disabled selected>Select your option</option> </select>"); getEmails(); } getEmails();
