laravel形式選擇動態變化值

Question

我有一些選擇的形式：

{!! Form::select('cl_1',array('' => 'No team') + $teams, null, ['class' => 'form-control', 'id' => 'cl_1']) !!} 
{!! Form::select('cl_2',array('' => 'No team') + $teams, null, ['class' => 'form-control', 'id' => 'cl_2']) !!} 

我怎麼能動態改變CL_2形式的價值時，我選擇CL_1值;

Answer 1

這個jQuery代碼添加到你的身體標記的末尾：

<script> 
    $(document).ready(
     $('#cl_1').change(function(
      $('#cl_2').val($('#cl_1').val()); //Or any code you need goes here 
     )); 
    ); 
</script> 

Answer 2

<script type="text/javascript"> 
    $(document).ready(function(){ 
     $("body").on("change","#cl_1",function(){ 
      $('#cl_2').val('1'); // You can put any value as your requirement 
     }); 
    }); 
</script>
