javascript - 修复了使用 jQuery 滚动时的 NavBar

Question

我的页面上有我的导航栏。我曾使用 CSS 和 jQuery 将其固定在顶部，但是当我在导航栏中选择任何菜单项时，它不会转到该部分。给我解决方案。

<header id="index-banner">
  <nav id="navigation" class="banner-header z-depth-0	">
    <ul class="left hide-on-med-and-down">
      <li><a href="http://localhost/project/" class="head"><span>HOME</span></a></li>
      <li><a href="#location" class="head" id="loc"><span>LOCATIONS</span></a>
        <li><a href="faq.php" class="head"><span>FAQ</span></a></li>
      </li>
    </ul>
    <a href="" class="center brand-logo"><img src="img/logo/50.png" class="banner-logo" id="mylogo"></a>

Answer 1

您必须使用“id”属性定义每个部分，然后您必须使用 “scrollTop” 进行那些将滚动到定义的“id”的导航。

HTML 代码

<a href="#target-element" class="scroll_to">Scroll to Target Element</a>

<section id=”target-element”>Target Element Content</section>

Jquery代码:

jQuery('.scroll_to').click(function(e){
    var jump = $(this).attr('href');
    var new_position = $(jump).offset();
    $('html, body').stop().animate({ scrollTop: new_position.top }, 500);
    e.preventDefault();
});
