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   lt option value 1 gt My option lt  option gt

User · Answer

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');

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

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

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  lt  len    i        html join   lt option value      data i   value        gt     data i   label       lt  option gt                       select   append html
