How to get Selected Text from select2 when using <input>
As of Select2 4.x, it always returns an array, even for non-multi select lists.
var data = $('your-original-element').select2('data')
alert(data[0].text);
alert(data[0].id);
For Select2 3.x and lower
Single select:
var data = $('your-original-element').select2('data');
if(data) {
alert(data.text);
}
Note that when there is no selection, the variable 'data' will be null.
Multi select:
var data = $('your-original-element').select2('data')
alert(data[0].text);
alert(data[0].id);
alert(data[1].text);
alert(data[1].id);
From the 3.x docs:
data Gets or sets the selection. Analogous to val method, but works with objects instead of ids.
data method invoked on a single-select with an unset value will return null, while a data method invoked on an empty multi-select will return [].
The correct way to do this as of v4 is:
$('.select2-chosen').select2('data')[0].text
It is undocumented so could break in the future without warning.
You will probably want to check if there is a selection first however:
var s = $('.select2-chosen');
if(s.select2('data') && !!s.select2('data')[0]){
//do work
}
Used this for show text
var data = $('#id-selected-input').select2('data');
data.forEach(function (item) {
alert(item.text);
})
I finally figured it out doing this:
var $your-original-element = $('.your-original-element');
var data = $your-original-element.select2('data')[0]['text'];
alert(data);
if you also want the value:
var value = $your-original-element.select2('data')[0]['id'];
alert(value);
