JavaScript 文字动画效果可以通过多种方式实现,以下是一些常见的文字动画效果及其示例代码:
这种效果模拟了打字机逐字打印文字的过程。
示例代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Typewriter Effect</title>
<style>
#text {
overflow: hidden; /* Ensures the content is not revealed until the animation */
border-right: .15em solid orange; /* The typwriter cursor */
white-space: nowrap; /* Keeps the content on a single line */
letter-spacing: .15em; /* Adjust as needed */
animation:
typing 3.5s steps(40, end),
blink-caret .75s step-end infinite;
}
/* The typing effect */
@keyframes typing {
from { width: 0 }
to { width: 100% }
}
/* The typewriter cursor effect */
@keyframes blink-caret {
from, to { border-color: transparent }
50% { border-color: orange }
}
</style>
</head>
<body>
<h1 id="text">Hello, World!</h1>
<script>
// JavaScript can be used to dynamically set the text content
document.getElementById('text').textContent = 'Your animated text here...';
</script>
</body>
</html>
这种效果会使文字快速闪烁。
示例代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Text Blinking</title>
<style>
.blinking {
animation: blinker 1s linear infinite;
}
@keyframes blinker {
50% { opacity: 0; }
}
</style>
</head>
<body>
<h1 class="blinking">Blinking Text!</h1>
</body>
</html>
这种效果会逐字显示文字。
示例代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Character by Character</title>
<script>
function typeWriter(text, i, callback){
if (i < text.length) {
document.querySelector("#text").innerHTML = text.substring(0, i+1);
setTimeout(function() {
typeWriter(text, i + 1, callback)
}, 100);
}
else if (typeof callback == "function") {
callback();
}
}
document.addEventListener("DOMContentLoaded", function() {
typeWriter("Hello, World!", 0);
});
</script>
</head>
<body>
<h1 id="text"></h1>
</body>
</html>
这种效果会使文字从一侧滚动到另一侧。
示例代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Text Scrolling</title>
<style>
.marquee {
width: 100%;
overflow: hidden;
white-space: nowrap;
box-sizing: border-box;
animation: marquee 15s linear infinite;
}
@keyframes marquee {
0% { transform: translateX(100%); }
100% { transform: translateX(-100%); }
}
</style>
</head>
<body>
<div class="marquee">Scrolling text goes here...</div>
</body>
</html>
以上是一些基本的文字动画效果及其实现方法,可以根据具体需求进行调整和扩展。
