$(\"#mySelect\").append(\'My         


        

Answer 1

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

Answer 2

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 3

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 4

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>");

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 6

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>
