问我有一个页面，它加载了一个地图。当我打开fancybox来显示一个图像时，它似乎被地图“切断”了

EN

// lock scroll position, but retain settings for later
  var scrollPosition = [
    self.pageXOffset || document.documentElement.scrollLeft || document.body.scrollLeft,
    self.pageYOffset || document.documentElement.scrollTop  || document.body.scrollTop
  ];
  var html = jQuery('html'); // it would make more sense to apply this to body, but IE7 won't have that
  html.data('scroll-position', scrollPosition);
  html.data('previous-overflow', html.css('overflow'));
  html.css('overflow', 'hidden');
  window.scrollTo(scrollPosition[0], scrollPosition[1]);


  // un-lock scroll position
  var html = jQuery('html');
  var scrollPosition = html.data('scroll-position');
  html.css('overflow', html.data('previous-overflow'));
  window.scrollTo(scrollPosition[0], scrollPosition[1])
