Block scroll on Modal open

问题

I'm working on this website, (Built using Fullpage.js plugin). In the first section I have a modal window (by clicking on the orange + symbol).

As you can see, if you scroll with the mouse when the Modal is open, you can scroll to the next page.

How can I block this? I need to make it scrollable ONLY when you close the Modal.

PS: I am using Wordpress if this could help...

EDIT: i tried this

<script type="text/javascript"> 
$(document).on('click', '.ts-awesome-plus', function() {
$.fn.fullpage.setAllowScrolling(false);
$.fn.fullpage.setKeyboardScrolling(false);
}); 
</script>

When the modal box is open you need to disable the scrolling with $.fn.fullpage.setAllowScrolling(false) and also the keyboard scrolling $.fn.fullpage.setAllowScrolling(false). On modal close just enable them. Here is a working example, click on Modal Open and Modal Close.

$('#fullpage').fullpage({
  anchors: ['page1', 'page2', 'page3', 'page4'],
  sectionsColor: ['yellow', 'orange', '#C0C0C0', '#ADD8E6'],
});

//adding the actions to the buttons
$(document).on('click', '#turnOff', function() {
  $.fn.fullpage.setAllowScrolling(false);
  $.fn.fullpage.setKeyboardScrolling(false);
});

$(document).on('click', '#turnOn', function() {
  $.fn.fullpage.setAllowScrolling(true);
  $.fn.fullpage.setKeyboardScrolling(true);
});

.section {
  text-align: center;
  font-size: 3em;
}
/**
Fixed button outside the fullpage.js wrapper
*/

#turnOff,
#turnOn {
  position: fixed;
  z-index: 999;
  font-size: 2em;
  cursor: pointer;
  top: 20px;
}
#turnOff {
  left: 20px;
}
#turnOn {
  left: 240px;
}
