如何使用固定导航修复 "Smooth Scrolling"

How to fix "Smooth Scrolling" with fixed navigation

一旦我设置了平滑滚动和固定导航,我就无法让锚停在上面添加的 100 像素处。它跳回到原来的散列。

我试过将偏移量设置为 100,但跳跃不成功。它在 Safari 上运行良好,但在 Chrome 或 Firefox 上运行不佳。

这是我用过的:

// URL updates and the element focus is maintained
// originally found via in Update 3 on http://www.learningjquery.com/2007/10/improved-animated-scrolling-script-for-same-page-links

// filter handling for a /dir/ OR /indexordefault.page
function filterPath(string) {
  return string
    .replace(/^\//, '')
    .replace(/(index|default).[a-zA-Z]{3,4}$/, '')
    .replace(/\/$/, '');
}

var locationPath = filterPath(location.pathname);
$('a[href*="#"]').each(function () {
  var thisPath = filterPath(this.pathname) || locationPath;
  var hash = this.hash;
  if ($("#" + hash.replace(/#/, '')).length) {
    if (locationPath == thisPath && (location.hostname == this.hostname || !this.hostname) && this.hash.replace(/#/, '')) {
      var $target = $(hash), target = this.hash;
      if (target) {
        $(this).click(function (event) {
          event.preventDefault();
          $('html, body').animate({scrollTop: $target.offset().top - 100}, 1000, function () {
            location.hash = target; 
            $target.focus();
            if ($target.is(":focus")){ //checking if the target was focused
              return false;
            }else{
              $target.attr('tabindex','-1'); //Adding tabindex for elements not focusable
              $target.focus(); //Setting focus
            };
          });       
        });
      }
    }
  }
});

我希望锚点比 link 所在的实际部分高 100 像素。

尝试始终 return false 在您的点击功能结束时。 这将阻止默认的浏览器行为

$(this).click(function (event) {
    event.preventDefault();
    // Your code
    return false;
});
