Take data from another field in yii2 form

I'm making a form with yii2, now I have two field: 

 <?php echo $form->field($model, 'Protocol')->textInput(['maxlength' => true])->dropDownList(
                    array("rtsp://"=>"rtsp","rsmt://"=>"rsmt","http://"=>"http"),     // Flat array ('id'=>'label')
                    ['prompt'=>'Select']     // options
                ); ?>

 <?php echo $form->field($model, 'url')->textInput(['maxlength' => true]); ?>

They look like this: form

How can I take the selection from Protocol's drop down list and automatically add it to the below URL field? Like this: enter image description here I type the http:// in the field manually, is there anyway I can make it automatic?

Add onchange event in your 'protocol' dropdownList. show below code

<?= $form->field($model, 'Protocol')->dropdownList(["rtsp://"=>"rtsp","rsmt://"=>"rsmt","http://"=>"http"], [
    'onchange'=>'$( "#'.Html::getInputId($model, 'url').'").val($(this).val());'

    ]) ?>

<?= $form->field($model, 'url')->textInput(['maxlength' => true]);
?>
