scrollIntoView 使用与属性详解

效果图如下图所示

如果要想让元素滚动到指定位置

window.onload = function () {containerItems[6].scrollIntoView({ behavior: "smooth" });
};

js 代码

const containerItems = document.querySelectorAll(".container div");
const gobackTop = document.querySelector(".gobackTop");window.onload = function () {containerItems[6].scrollIntoView({ behavior: "smooth" });
};gobackTop.addEventListener("click", function () {window.scrollTo(0, 0);
});

html 元素

<div class="container"><div><h1>1</h1></div><div><h1>2</h1></div><div><h1>3</h1></div><div><h1>4</h1></div><div><h1>5</h1></div><div><h1>6</h1></div><div><h1>7</h1></div><div><h1>8</h1></div><div><h1>9</h1></div><div><h1>10</h1></div><div><h1>11</h1></div><div><h1>12</h1></div><div><h1>13</h1></div><div><h1>14</h1></div><div><h1>15</h1></div><div><h1>16</h1></div>
</div><div class="gobackTop">返回顶部</div>

css 样式

html {/* 平滑滚动到顶部 */scroll-behavior: smooth;
}.container {margin: 0 auto;width: 300px;
}.container > div {width: 300px;height: 300px;text-align: center;line-height: 300px;background-color: #efcd11;
