本文介绍如何使用 JavaScript 和 HTML 实现鼠标移动时的文字拖尾特效。通过监听鼠标位置事件，动态创建并更新 DOM 元素，利用定时器调整文字颜色和透明度，从而在鼠标移动路径上生成渐隐的文字效果。
JS实现鼠标移动拖尾效果
本文分享了一段使用 JavaScript 实现鼠标移动时产生文字拖尾效果的完整代码，供读者参考学习。
JavaScript 代码实现
以下是实现该效果所需的 JavaScript 代码部分。
function getMousePos(event) {
var e = event || window.event;
var mouseInfo = {
mouseX : e.clientX,
mouseY : e.clientY
}
return mouseInfo;
}
function getMouseArt() {
this.artStyle = {
position: "fixed",
top: 0,
left: 0,
width: "50px",
height: "50px",
"font-size": 0,
"color": 0,
"text-transform": 0
};
this.init = function(obj) {
var character = ["你", "真", "的", "爱", "我", "吗", "喜", "欢", "不", "对", "起", "彩", "色", "世", "界", "灰", "?"];
var font_trans = ["uppercase", "lowercase"];
this.Alpha = 1;
this.element = document.createElement('div');
var text = document.createTextNode(character[Math.floor(Math.random() * character.length)]);
this.element.appendChild(text);
this.addStyle(this.element, this.artStyle);
var offsetV = Math.floor(Math.random() * 60 - 30); // -30 ~ 30
this.element.style.left = obj.mouseX + offsetV +"px"; // x
this.element.style.top = obj.mouseY + offsetV +"px"; // y
this.element.style.fontSize = Math.floor(Math.random() * 20 + 10) + "px";
this.element.style.color = "hsla("+ Math.floor(Math.random() * 255) + ",100%,50%," + this.Alpha + ")";
this.element.style.textTransform = font_trans[Math.floor(Math.random() * 2)];
document.body.appendChild(this.element);
}
this.addStyle = function(ele, genuine) {
for (var k in genuine) {
ele.style[k] = genuine[k];
}
}
this.delElement = function() {
document.body.removeChild(this.element);
}
this.reduceColor = function(win) {
if (this.Alpha <= 1 && this.Alpha > 0) {
this.Alpha = this.Alpha - 0.1;
this.element.style.color = "hsla("+ Math.floor(Math.random() * 255) + ",100%,50%," + this.Alpha + ")";
console.log(this.Alpha);
}
else {
clearInterval(win);
this.delElement();
}
}
}
document.onmousemove = function(event) {
var obj = getMousePos(event);
var art = new getMouseArt();
art.init(obj);
var win = setInterval(function() {
art.reduceColor(win);
}, 30);
}HTML 结构代码
接下来是配合 JavaScript 使用的 HTML 结构代码。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
body {
background: black;
}
</style>
</head>
<body>
<script src="mouse.js" type="text/javascript"></script>
</body>
</html>以上就是实现鼠标移动拖尾效果的全部内容，希望这段代码能对你的学习有所帮助，也欢迎继续关注本站获取更多技术分享。
