哈哈。我的小项目遇到了麻烦。我已经创建了<a href="slogannya">some icon</a>，<blockquote id="slogannya">但是当我单击<a>标签时它不起作用。这是我的代码：

html

<section class="to-content">
        <a class="scrollTo" href="#slogannya">
          <button type="button">
            <i class="material-icons">keyboard_arrow_down</i>
          </button>
        </a>
      </section>
      <section class="slogan">
        <blockquote id="slogannya">
          <p>Wanna create an event? <br> or you want to give some advice to us? Use the form below </p>
        </blockquote>
      </section>

jQuery

$(document).ready(function () {
  $(".scrollTo").on('click', function (e) {
      e.preventDefault();
      var target = $(this).attr('href');
      $('html, body').animate({
          scrollTop: ($(target).offset().top)
      }, 2000);
  });

});

我怎样才能使这项工作？请帮我 ：）

编辑

我知道我的问题是什么。在我的项目中，我有一个名为“general.css”的 css（此 css 内容 css 重置和任何页面的其他样式）。在这个 css 中，它使任何元素成为box-sizing: border-box;和其他样式。不知道具体是什么问题。但是当我删除我的“general.css”时，平滑滚动就可以了。谢谢你所有的回答朋友:)，我很感激！！

您所需要的只是 HTML 一些<a>nchors 和任何您想要的元素（甚至更多<a>的 nchors 会发疯）。顺便说一句，定位 id 对您不起作用的原因是因为需要urlhref的前缀。#前任。<a href="#ID"...它可能不起作用的另一个原因是<a>nchor 和目标元素彼此太近，因此理想情况下，目标至少应该足够远，以至于需要滚动才能到达那里。

  • 对于目标元素，确保它具有#id. 前任<div id='ID'...

  • 接下来，对于每个目的地，创建一个或多个<a>nchors 并将它们的href值设置为#+ID。前任。<a href='#ID...

  • 如果目标元素恰好是一个<a>nchor，我们也可以使用该name属性。前任。<a name='NAME'...

实际上它可以工作，但问题是 blockquote 标签紧跟在锚标签之后，但如果你在它们之间留出一个空格，你会看到动画在起作用

简而言之：只有当滚动条出现在窗口上并且两个元素之间有空格时，动画才会起作用看下面的例子，你会看到它起作用 

$(document).ready(function () {
  $(".scrollTo").on('click', function (e) {
console.log('clicked');
      e.preventDefault();
      var target = $(this).attr('href');
      $('html, body').animate({
          scrollTop: ($(target).offset().top)
      }, 2000);
  });

});
.any{
height:400px ;
width : 100% ; 
  
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section class="to-content">
        <a class="scrollTo" href="#slogannya">
          <button type="button">
            <i class="material-icons">keyboard_arrow_down</i>
         
          </button>
        </a>
      </section>
      <div class='any'></div>
      <section class="slogan">
        <blockquote id="slogannya">
          <p>Wanna create an event? <br> or you want to give some advice to us? Use the form below </p>
        </blockquote>
      </section>

它正在工作，但提供的代码没有滚动高度，也不是平滑滚动。如果不是这种情况，试试这个。

$(document).ready(function() {
  $("a").on('click', function(event) {

    if (this.hash !== "") {
      event.preventDefault();
      var hash = this.hash;

      $('html, body').animate({
        scrollTop: $(hash).offset().top
      }, 1500, function() {

        window.location.hash = hash;
      });
    }
  });
});
.to-content {
  height: 2000px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section class="to-content">
  <a href="#slogannya">
    <button type="button">
            <i class="material-icons">keyboard_arrow_down</i>
          </button>
  </a>
</section>
<section class="slogan">
  <blockquote id="slogannya">
    <p>Wanna create an event? <br> or you want to give some advice to us? Use the form below </p>
  </blockquote>
