Enable or disable touch scrolling on phones. This is only best for when you have a fixed menu that takes the view port view and does not scroll at all. See wiki for menu in action.

Enable or disable mobile touch scrolling.

module.exports = function() {

  var $nav            = $('.nav-global'),
      $toggle         = $('.menu-trigger'),
      $active_class   = 'nav-active',
      prevent_default = function(e) {
        e = e || window.event;
        if (e.preventDefault)
           e.preventDefault();
        e.returnValue = false;
      },
      disable_scroll = function() {
        $('body').bind('touchmove', function(e){
          e.preventDefault();
        });
        console.log('scroll disable');
      },
      enable_scroll = function() {
        $('body').unbind('touchmove');
        console.log('scroll enable');
      };

  // Toggle navigation
  $toggle.on('click touch', function(){
    $('body').toggleClass($active_class);
    // Disable touch scrolling if nav is active
    if ( $('body').hasClass($active_class) ) {
      disable_scroll();
    } else {
      enable_scroll();
    }
  });
