Document:head 属性

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Document 接口的 head 只读属性返回当前文档的 <head> 元素。

示例

html
<!doctype html>
<head id="my-document-head">
  <title>示例:使用 document.head</title>
</head>

<script>
  const theHead = document.head;

  console.log(theHead.id); // "my-document-head";

  console.log(theHead === document.querySelector("head")); // true
</script>

备注

document.head 是只读的。尝试给这个属性赋值将会静默失败,或者在严格模式下抛出 TypeError
