Ändern Sie die Textfarbe beim Scrollen

Ich erstelle eine Portfolio-Website und möchte, dass mein fester Text in einigen Teilen seine Farbe ändert. Wie kann ich das tun? Ich kann meinen Code nicht posten, weil er zu groß und zu lang ist, aber es wäre großartig, wenn Sie ein Codebeispiel geben könnten. So sieht es aus (https://olaolu.dev), Sie können sehen, wie die Schaltflächen und Namen werden beim Scrollen in den Farben geändert :)

P. Bitte verwenden Sie dazu js, danke!

Ich habe versucht, nach Informationen zu suchen, aber nichts gefunden :(

    我认为你需要的是一个交叉点观察者。交叉口观察器允许您“观察”目标并在目标可见时做出反应。

    我创建了一个小例子来演示这一点。我们正在观察第二节。当它可见时，我们将颜色更改为紫色。当它不可见时，我们将其改回黑色。

    const title = document.querySelector('.topbar__title');
const sectionOne = document.querySelector('.section--one');
const sectionTwo = document.querySelector('.section--two');

const observer = new IntersectionObserver((entry, observer) => {
  entry[0].isIntersecting > 0 ?
    title.style.color = sectionTwo.getAttribute('data-color') :
    title.style.color = sectionOne.getAttribute('data-color')
});

observer.observe(sectionTwo);
    * {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.topbar {
  position: fixed;
  top: 0;
  left: 0;
  padding: 1rem;
  width: 100%;
  background-color: white;
}

.section {
  height: 150vh;
  width: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
}

.section--one {
  background-color: white;
}

.section--two {
  background-color: rgb(255 0 0 / 5%);
}
    
  
    Title
    

    


    
  
    Section One
    

    


    
  
    Section Two

    当然你可以观察多个部分，或者改变一个类而不是用JS设置样式。这只是一个简单的例子......

    MDN 上有一些关于 Intersection Observers 的好信息
