add style to body when modal is open

I just want to add style to the body when my modal popup is open. After that it needs to remove when modal popup is closed. I just tried with this code. But not working at all. 

if( $('.modal').hasClass('in') === true ) {
  $('body').style({ 'overflow': "hidden" });
  }

Here is the fiddle

Instead of changing CSS with JavaScript I would recommend you to use HTML classes instead:

var $body = $('body');

$('#myModal').on({
    'show.bs.modal': function() { $body.addClass('visible') },
    'hide.bs.modal': function() { $body.removeClass('visible') }
});

And CSS:

body {
    transition: .5s background;
}

body.visible {
    background: red;
}

And here is jFiddle.

You can use bootstrap modal events. https://getbootstrap.com/docs/3.3/javascript/#modals-events

$('.modal').on('shown.bs.modal', function (e) {
  $('body').style({ 'overflow': "hidden" });
})

You can try the events shown.bs.modal and hidden.bs.modal. Also you are using the wrong function style you need to change that to css.

$('#myModal').on('shown.bs.modal', function(){
  $('body').css({ 'overflow': "hidden" });
}).on('hidden.bs.modal', function(){
  $('body').css({ 'overflow': "auto" });
});


$('#myModal').on('shown.bs.modal', function(){
  $('body').css({ 'overflow': "hidden" });
}).on('hidden.bs.modal', function(){
  $('body').css({ 'overflow': "auto" });
})
@import url('//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-theme.min.css');

body {
    margin: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<!-- Button trigger modal -->
