Adding options to a <select> using jQuery?

Question

What's the easiest way to add an option to a dropdown using jQuery?

Will this work?

$("#mySelect").append('<option value=1>My option</option>');

Answer 1

This did NOT work in IE8 (yet did in FF):

$("#selectList").append(new Option("option text", "value"));

This DID work:

var o = new Option("option text", "value");
/// jquerify the DOM object 'o' so we can use the html method
$(o).html("option text");
$("#selectList").append(o);

Answer 2

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 
    }));
});

Answer 3

You can add option using following syntax, Also you can visit to way handle option in jQuery for more details.

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

2. $('#select').append('<option value="1">One</option>');

3. var option = new Option(text, value); $('#select').append($(option));

Answer 4

If the option name or value is dynamic, you won't want to have to worry about escaping special characters in it; in this you might prefer simple DOM methods:

var s= document.getElementById('mySelect');
s.options[s.options.length]= new Option('My option', '1');

Answer 5

Option 1-

You can try this-

$('#selectID').append($('<option>',
 {
    value: value_variable,
    text : text_variable
}));

Like this-

for (i = 0; i < 10; i++)
{ 
     $('#mySelect').append($('<option>',
     {
        value: i,
        text : "Option "+i 
    }));
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<select id='mySelect'></select>

Option 2-

Or try this-

$('#selectID').append( '<option value="'+value_variable+'">'+text_variable+'</option>' );

Like this-

for (i = 0; i < 10; i++)
{ 
     $('#mySelect').append( '<option value="'+i+'">'+'Option '+i+'</option>' );
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<select id='mySelect'></select>

Answer 6

This is very simple:

$('#select_id').append('<option value="five" selected="selected">Five</option>');

or

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

Answer 7

That works well.

If adding more than one option element, I'd recommend performing the append once as opposed to performing an append on each element.

Answer 8

for whatever reason doing $("#myselect").append(new Option("text", "text")); isn't working for me in IE7+

I had to use $("#myselect").html("<option value='text'>text</option>");

Answer 9

To help performance you should try to only alter the DOM once, even more so if you are adding many options.

var html = '';

for (var i = 0, len = data.length; i < len; ++i) {
    html.join('<option value="' + data[i]['value'] + '">' + data[i]['label'] + '</option>');
}           

$('#select').append(html);

Answer 10

$('#mySelect').empty().append('<option value=1>My option</option>').selectmenu('refresh');

Answer 11

I like to use non jquery approach:

mySelect.add(new Option('My option', 1));

Answer 12

You can add options dynamically into dropdown as shown in below example. Here in this example I have taken array data and binded those array value to dropdown as shown in output screenshot

Output:

var resultData=["Mumbai","Delhi","Chennai","Goa"]
$(document).ready(function(){
   var myselect = $('<select>');
     $.each(resultData, function(index, key) {
	     myselect.append( $('<option></option>').val(key).html(key) );
       });
      $('#selectCity').append(myselect.html());
});

<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js">
</script>

<select  id="selectCity">

</select>

Answer 13

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 14

Not mentioned in any answer but useful is the case where you want that option to be also selected, you can add:

var o = new Option("option text", "value");
o.selected=true;
$("#mySelect").append(o);

Answer 15

Why not simply?

$('<option/>')
  .val(optionVal)
  .text('some option')
  .appendTo('#mySelect')

Answer 16

There are two ways. You can use either of these two.

First:

$('#waterTransportationFrom').append('<option value="select" selected="selected">Select From Dropdown List</option>');

Second:

$.each(dataCollecton, function(val, text) {            
    options.append($('<option></option>').val(text.route).html(text.route));
});

Answer 17

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 18

If you want to insert the new option at a specific index in the select:

$("#my_select option").eq(2).before($('<option>', {
    value: 'New Item',
    text: 'New Item'
}));

This will insert the "New Item" as the 3rd item in the select.

Answer 19

You can append and set the Value attribute with text:

$("#id").append($('<option></option>').attr("value", '').text(''));
$("#id").append($('<option></option>').attr("value", '4').text('Financial Institutions'));

Answer 20

We found some problem when you append option and use jquery validate. You must click one item in select multiple list. You will add this code to handle:

$("#phonelist").append("<option value='"+ 'yournewvalue' +"' >"+ 'yournewvalue' +"</option>");

$("#phonelist option:selected").removeAttr("selected"); // add to remove lase selected

$('#phonelist option[value=' + 'yournewvalue' + ']').attr('selected', true); //add new selected

Answer 21

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 22

$('#select_id').append($('<option>',{ value: v, text: t }));

Answer 23

This is just a quick points for best performance

always when you are dealing with many options, build a big string and then add it to the 'select' for best performance

f.g.

var $mySelect = $('#mySelect'); var str = '';

$.each(items, function (i, item) {
    // IMPORTANT: no selectors inside the loop (for the best performance)
    str += "<option value='" + item.value + "'> " + item.text + "</option>";
});
// you built a big string

$mySelect.html(str); // <-- here you add the big string with a lot of options into the selector.
$mySelect.multiSelect('refresh');

Even faster

var str = ""; 
for(var i; i = 0; i < arr.length; i++){
    str += "<option value='" + item[i].value + "'> " + item[i].text + "</option>";
}    
$mySelect.html(str);
$mySelect.multiSelect('refresh');

Answer 24

This is the way i did it, with a button to add each select tag.

$(document).on("click","#button",function() {
   $('#id_table_AddTransactions').append('<option></option>')
}

Answer 25

$(function () {
     var option = $("<option></option>");
     option.text("Display text");
     option.val("1");
     $("#Select1").append(option);
});

If you getting data from some object, then just forward that object to function...

$(function (product) {
     var option = $("<option></option>");
     option.text(product.Name);
     option.val(product.Id);
     $("#Select1").append(option);
});

Name and Id are names of object properties...so you can call them whatever you like...And ofcourse if you have Array...you want to build custom function with for loop...and then just call that function in document ready...Cheers

Answer 26

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 27

If someone comes here looking for a way to add options with data properties

Using attr

var option = $('<option>', { value: 'the_value', text: 'some text' }).attr('family', model.family);

Using data - version added 1.2.3

var option = $('<option>', { value: 'the_value', text: 'some text' }).data('misc', 'misc-value);

Answer 28

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 29

You can do this in ES6:

$.each(json, (i, val) => {
    $('.js-country-of-birth').append(`<option value="${val.country_code}"> ${val.country} </option>`);
  });

Answer 30

Try

mySelect.innerHTML+= '<option value=1>My option</option>';

btn.onclick= _=> mySelect.innerHTML+= `<option selected>${+new Date}</option>`

<button id="btn">Add option</button>

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