如何设置 Yii2 Radiolist ID 和 onchange 方法

Question

我在 yii2 中创建了 radiolist，如下所示。如何在其中设置 onchange 方法。以及如何为 radiolist 设置 id

<?= $form->field($model, 'design_type')->inline()->radioList(['a' => 'Classic Design', 'b' => 'New Design'])->label(false) ?>

Answer 1

You must add options after items in radioList:

change code to:

<?= $form->field($model, 'design_type')->inline()->radioList(['a' => 'Classic Design', 'b' => 'New Design'],['onChange'=>'handleRadio(this);','id'=>'whatever'])->label(false) ?>

Answer 2

Try this code to add any attribute in your input:radio field

$form->field($model, 'design_type')->radioList(['a' => 'Classic Design', 'b' => 'New Design'], [
    'item' => function($index, $label, $name, $checked, $value) {
        $checked = $checked ? 'checked' : '';
        return "<label>
                <input type='radio' {$checked} 
                       name='{$name}' 
                       value='{$value}'
                       id='idName_{$value}'
                       onChange='YourFunctionName();'>
                {$label}</label>";

    }
])
