$('#category-id').empty();
for (i = 0; i < response[0].category.length; i++) {
$('#category-id').append($('<option></option>') //here typo mistake
.attr('value', response[0].category[i].id)
.attr('selected', 'selected')
.text(response[0].category[i].category_name));
}
This is from javascript code _form.php in Transaction View. It is triggered by radiobutton click. Select2 contains income and expense categories. When I selected one income category and clicked expense radio button. The option changed expense categories. But the selected income category still showed. It didn't clear.
<?=
$form->field($model, 'category_id')->widget(Select2::classname(), [
'data' => Category::getCategoryListByType($model->transaction_type),
'options' => [
'id' => 'category-id',
'placeholder' => Yii::t('frontend/common', 'Please select one'),
'allowClear' => true,
],
'pluginOptions' => ['allowClear' => true]
]);
?>
Select2 php code. Please help. Thank you.
This is worked for me-
$('#accessories').val('').trigger("change");
'#accessories' is the id of select2
