#### When the left checkbox is checked then all the chekbox that are right on the right side must be cheked

I have tried this code but it only worked once after that i have to refresh the page and then again it will work only once.

 enter code here<tr class="all">
<!--Guarito=Healed  -->
<th style="width:30vh" class="table-info">Guarito</th>

@for($i=0;$i<4;$i++) <td> <input type="checkbox" name="Guarito-{{$i}}" id="Guarito-{{$i}}" class="selectall" @if(!empty($FollowupTreatment[$i] ->guarito) &&$FollowupTreatment[$i] ->guarito == 1) checked @endif > </td> </tr>  Here is the code between script tag $('.selectall').click(function() {

if ($(this).is(':checked')) {$('.all input').attr('checked', true);
} else {
\$('.all input').attr('checked', false);
}
});
