Hello, Friend try this JQuery

$(document).ready(function(){
if($('#s:checked').length){
$('#sr').attr('readonly',true); // On Load, should it be read only?
}

$('#s').change(function(){
if($('#s:checked').length){
$('#sr').attr('readonly',true); //If checked - Read only
}else{
$('#sr').attr('readonly',false);//Not Checked - Normal
}
});
});
