锚标记无效。请帮助这个新手

问题描述 投票：2回答：1

这是问题所在的实际视频记录（我不打算以任何方式做广告）：https://www.youtube.com/watch?v=7b38cQ0VGWI

因此，我只是出于练习的目的创建了一个网站，一切进展顺利，直到遇到这个问题。我有2个菜单，其中顶部主导航栏将一个引导至另一页，而第二个导航栏将一个引导至相同页面中的特定部分。但是我在第二个导航栏上遇到了问题。所以下面是我正在使用的html：

<nav class="navbar">
        <div class="container">
            <ul>
                <li><a href="#drama">Drama</a></li>
                <li><a href="#comedy">Comedy</a></li>
                <li><a href="#romance">Romance</a></li>
                <li><a href="#action">Action</a></li>
            </ul>
        </div>
    </nav>

这是一系列的电影图片列表之后，但我仅以下面的输入2为例：

<div class="grid-picture">
    <!--First row of movies-->
        <div id="action">
            <div class="movies">
                <a href="https://www.imdb.com/title/tt2911666/" target="_blank">
                <img src="https://images-na.ssl-images-amazon.com/images/I/91atCmxi6hL._UR1200,1600_RI_.jpg">
                    <h3>John Wick</h3>
                        <p>Action, Crime, Triller</p>
                </a>
            </div>
        </div>
<br>
        <!--1st row of romance movies-->
        <div id="romance">
            <div class="movies">
                <a href="https://www.imdb.com/title/tt1638002/?ref_=nv_sr_srsg_0">
                <img src="https://kbimages1-a.akamaihd.net/beb95aaa-36b7-444d-8557-0cb7efa8e898/1200/1200/False/love-rosie-1.jpg">
                    <h3>Love, Rosie</h3>
                        <p>Comedy, Romance</p>
                </a>
            </div>
       </div>
</div>

如您所见，“ John Wick”位于div标签中，ID为“ action”，而“ Love，Rosie”位于div标签中，ID为“ romance”。现在，“动作”链接可以正常工作；它将页面准确地定向到“动作” ID中的电影所在的位置。但是，当我单击“浪漫”链接时，它并没有带我进入网站底部。相反，它会将我带到与单击“操作”链接相同的位置。

所以基本上，即使我确保输入href =“＃romance”锚标签也对我不起作用，并且还要确保将div标签中的电影“ Love，Rosie”用ID“浪漫”。外部链接可以正常工作，只是内部链接不能像我想象的那样工作。我还四重检查是否有未关闭的div标签，但事实并非如此。有人可以在这里帮助一个新学习者吗？ ps。所有电影都在同一页面中

我认为您正在寻找此gallery filter

filterSelection("all")
function filterSelection(c) {
  var x, i;
  x = document.getElementsByClassName("column");
  if (c == "all") c = "";
  for (i = 0; i < x.length; i++) {
    w3RemoveClass(x[i], "show");
    if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
  }
}

function w3AddClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    if (arr1.indexOf(arr2[i]) == -1) {element.className += " " + arr2[i];}
  }
}

function w3RemoveClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    while (arr1.indexOf(arr2[i]) > -1) {
      arr1.splice(arr1.indexOf(arr2[i]), 1);     
    }
  }
  element.className = arr1.join(" ");
}


// Add active class to the current button (highlight it)
var btnContainer = document.getElementById("myBtnContainer");
var btns = btnContainer.getElementsByClassName("btn");
for (var i = 0; i < btns.length; i++) {
  btns[i].addEventListener("click", function(){
    var current = document.getElementsByClassName("active");
    current[0].className = current[0].className.replace(" active", "");
    this.className += " active";
  });
