JS实现鼠标样式
不建议更改,因为默认就是最简洁
在docs/javascripts/extra.js
下复制粘贴:
Java |
---|
| var CURSOR;
Math.lerp = (a, b, n) => (1 - n) * a + n * b;
const getStyle = (el, attr) => {
try {
return window.getComputedStyle
? window.getComputedStyle(el)[attr]
: el.currentStyle[attr];
} catch (e) {}
return "";
};
class Cursor {
constructor() {
this.pos = {curr: null, prev: null};
this.pt = [];
this.create();
this.init();
this.render();
}
move(left, top) {
this.cursor.style["left"] = `${left}px`;
this.cursor.style["top"] = `${top}px`;
}
create() {
if (!this.cursor) {
this.cursor = document.createElement("div");
this.cursor.id = "cursor";
this.cursor.classList.add("hidden");
document.body.append(this.cursor);
}
var el = document.getElementsByTagName('*');
for (let i = 0; i < el.length; i++)
if (getStyle(el[i], "cursor") == "pointer")
this.pt.push(el[i].outerHTML);
document.body.appendChild((this.scr = document.createElement("style")));
// 这里改变鼠标指针的颜色 由svg生成
this.scr.innerHTML = `* {cursor: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 8 8' width='8px' height='8px'><circle cx='4' cy='4' r='4' opacity='.5'/></svg>") 4 4, auto}`;
}
refresh() {
this.scr.remove();
this.cursor.classList.remove("hover");
this.cursor.classList.remove("active");
this.pos = {curr: null, prev: null};
this.pt = [];
this.create();
this.init();
this.render();
}
init() {
document.onmouseover = e => this.pt.includes(e.target.outerHTML) && this.cursor.classList.add("hover");
document.onmouseout = e => this.pt.includes(e.target.outerHTML) && this.cursor.classList.remove("hover");
document.onmousemove = e => {(this.pos.curr == null) && this.move(e.clientX - 8, e.clientY - 8); this.pos.curr = {x: e.clientX - 8, y: e.clientY - 8}; this.cursor.classList.remove("hidden");};
document.onmouseenter = e => this.cursor.classList.remove("hidden");
document.onmouseleave = e => this.cursor.classList.add("hidden");
document.onmousedown = e => this.cursor.classList.add("active");
document.onmouseup = e => this.cursor.classList.remove("active");
}
render() {
if (this.pos.prev) {
this.pos.prev.x = Math.lerp(this.pos.prev.x, this.pos.curr.x, 0.15);
this.pos.prev.y = Math.lerp(this.pos.prev.y, this.pos.curr.y, 0.15);
this.move(this.pos.prev.x, this.pos.prev.y);
} else {
this.pos.prev = this.pos.curr;
}
requestAnimationFrame(() => this.render());
}
}
(() => {
CURSOR = new Cursor();
// 需要重新获取列表时,使用 CURSOR.refresh()
})();

其中比较重要的参数就是鼠标的尺寸和颜色,已经在上图中标出,目前发现颜色只支持RGB写法和固有名称写法(例如red这种),其他参数也可以自行摸索:
Java |
---|
| * {cursor: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 8 8' width='8px' height='8px'><circle cx='4' cy='4' r='4' opacity='1.0' fill='rgb(57, 197, 187)'/></svg>") 4 4, auto}`
|
在docs/stylesheets/extra.css添加如下代码:
CSS |
---|
| /* 鼠标样式 */
#cursor {
position: fixed;
width: 16px;
height: 16px;
/* 这里改变跟随的底色 */
background: var(--theme-color);
border-radius: 8px;
opacity: 0.25;
z-index: 10086;
pointer-events: none;
transition: 0.2s ease-in-out;
transition-property: background, opacity, transform;
}
#cursor.hidden {
opacity: 0;
}
#cursor.hover {
opacity: 0.1;
transform: scale(2.5);
-webkit-transform: scale(2.5);
-moz-transform: scale(2.5);
-ms-transform: scale(2.5);
-o-transform: scale(2.5);
}
#cursor.active {
opacity: 0.5;
transform: scale(0.5);
-webkit-transform: scale(0.5);
-moz-transform: scale(0.5);
-ms-transform: scale(0.5);
-o-transform: scale(0.5);
}
|
这里比较重要的参数就是鼠标跟随的圆形颜色,可以根据自己的喜好进行更改:
CSS |
---|
| #cursor {
/* 这里改变跟随的底色 */
background: rgb(57, 197, 187);
}
|
注意⚠️
需要在mkdocs.yml中引入js和css
