[英]Yii2 Select2 doesn't clear selected value after select2.empty()
$('#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.这是来自事务视图中的 javascript 代码_form.php 。 It is triggered by radiobutton click.
它由单选按钮单击触发。 Select2 contains income and expense categories.
Select2 包含收入和费用类别。 When I selected one income category and clicked expense radio button.
当我选择一个收入类别并单击费用单选按钮时。 The option changed expense categories.
该选项更改了费用类别。 But the selected income category still showed.
但选择的收入类别仍然显示。 It didn't clear.
没说清楚。
<?=
$form->field($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.选择2 php代码。 Please help.
请帮忙。 Thank you.
谢谢。
This is worked for me-这对我有用-
$('#accessories').val('').trigger("change");
'#accessories' is the id of select2 '#accessories' 是 select2 的 id
