Answer 1

How about this

var numbers = [1, 2, 3, 4, 5];
var option = '';

for (var i=0;i<numbers.length;i++){
     option += '<option value="'+ numbers[i] + '">' + numbers[i] + '</option>';
    }

    $('#items').append(option);

Answer 2

var select = $('#myselect');
var newOptions = {
                'red' : 'Red',
                'blue' : 'Blue',
                'green' : 'Green',
                'yellow' : 'Yellow'
            };
$('option', select).remove();
$.each(newOptions, function(text, key) {
    var option = new Option(key, text);
    select.append($(option));
});

Answer 3

if u have optgroup inside select, u got error in DOM.

I think a best way:

$("#select option:last").after($('<option value="1">my option</option>'));

Answer 4

Based on dule's answer for appending a collection of items, a one-liner for...in will also work wonders:

let cities = {'ny':'New York','ld':'London','db':'Dubai','pk':'Beijing','tk':'Tokyo','nd':'New Delhi'};

for(let c in cities){$('#selectCity').append($('<option>',{value: c,text: cities[c]}))}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script>
<select  id="selectCity"></select>

Both object values and indexes are assigned to the options. This solution works even in the old jQuery (v1.4)!

Answer 5

U can try below code to append to option

  <select id="mySelect"></select>

    <script>
          $("#mySelect").append($("<option></option>").val("1").html("My enter code hereoption"));
    </script>

Answer 6

Personally, I prefer this syntax for appending options:

$('#mySelect').append($('<option>', {
    value: 1,
    text: 'My option'
}));

If you're adding options from a collection of items, you can do the following:

$.each(items, function (i, item) {
    $('#mySelect').append($('<option>', { 
        value: item.value,
        text : item.text 
    }));
});
