There are two ways to programmatically access the current selection data: using .select2('data')
, or by using a jQuery selector.
Using the data
method
Calling select2('data')
will return a JavaScript array of objects representing the current selection. Each object will contain all of the properties/values that were in the source data objects passed through processResults
and templateResult
callbacks (as in Loading data from an array and Connecting to a remote data source).
$('#mySelect2').select2('data');
Using a jQuery selector
Selected items can also be accessed via the :selected
jQuery selector:
$('#mySelect2').find(':selected');
It is possible to extend the <option>
elements representing selection with the HTML data-* attributes containing arbitrary data from the source data objects:
$('#mySelect2').select2({
// ...
templateSelection: function (data, container) {
$(data.element).attr('data-custom-attribute', data.customValue);
return data.text;
}
});
// Retrieve custom attribute value of the first selected element
$('#mySelect2').find(':selected').attr('data-custom-attribute')
