我有一个按钮，当你将鼠标悬停在它上面时，它开始磁化到光标，但内容（箭头）仍然存在，但我也需要它来磁化，怎么做？
这个网站上有一个例子https://www.m-trust.co.jp/，这是我的代码
我搜索了论坛，自己尝试过，但没有任何效果:(
function btnRun() {
// Двигающаяся кнопка
let offset = 70,
cur = false;
document.body.addEventListener('mouseenter', function(e) {
if (e.target.classList.contains('btn') && cur === false) {
cur = {
e: e.target,
x: e.target.getBoundingClientRect().left,
y: e.target.getBoundingClientRect().top
};
}
}, true);
document.addEventListener('mousemove', function(e) {
if (cur !== false) {
let x = (e.clientX - cur.x) - (cur.e.getBoundingClientRect().width / 2),
y = (e.clientY - cur.y) - (cur.e.getBoundingClientRect().height / 2);
cur.e.style.transform = `translate(${x}px,${y}px)`;
//
if (Math.abs(x) >= offset || Math.abs(y) >= offset) {
cur.e.style.transform = 'translate(0,0)';
cur = false;
}
}
});
}
