锚点不滚动到最顶部

时间：2020-11-04 09:01:52

标签： javascript html jquery css

单击 home 时，您不会滚动到最顶部。您仍然需要手动滚动一些内容。我该如何置顶？

可以使用position: sticky代替position: fixed更好的选择吗？

如果是的话，如何正确替换导航栏的状态？

// header Effekt beim scrollen

$(function() {
  var shrinkHeader = 100;
  $(window).scroll(function() {
    var scroll = getCurrentScroll();
    if (scroll >= shrinkHeader) {
      $('#navbar').addClass('shrink');
    } else {
      $('#navbar').removeClass('shrink');
    }
  });

  function getCurrentScroll() {
    return window.pageYOffset || document.documentElement.scrollTop;
  }
});
// JavaScript Document

$(document).ready(function() {

  var navTop = $('#navbar').offset().top;
  var navHeight = $('#navbar').height();
  var windowH = $(window).height();

  $('.section').height(windowH);

  $(document).scroll(function() {
    var st = $(this).scrollTop();

    //for the nav bar:
    if (st > navTop) {
      $('#navbar').addClass('fix');
      $('.section:eq(0)').css({
        'margin-top': navHeight
      }); //fix  scrolling issue due to the fix nav bar
    } else {
      $('#navbar').removeClass('fix');
      $('.section:eq(0)').css({
        'margin-top': '0'
      });
    }

    $('.section').each(function(index, element) {
      if (st + navHeight > $(this).offset().top && st + navHeight <= $(this).offset().top + $(this).height()) {
        $(this).addClass('active');

        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').parent('li').addClass('active');
        // or $('#nav li:eq('+index+')').addClass('active');
      } else {
        $(this).removeClass('active');

        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').parent('li').removeClass('active');
        //or $('#nav li:eq('+index+')').removeClass('active');
      }

    });

  });

我必须将其更改为此：

#home {
  height: 100% !important;
  display: block;
  padding-top: 128px;
  z-index: -1;
  position: relative;
  top: -128px;
}

更新您的CSS代码

body {
  background-color: white;
/*  margin: 128px 0 0 0; */  comment this line or change to margin:0px; 
}
