HTML DOM closest() 方法

❮ Element 对象

实例

找到与 CSS 选择器匹配的最近元素,并给它一个黄色边框:

var element = document.getElementById("myElement");
var closest = element.closest(".container");
if (closest) {
  closest.style.border = "10px solid yellow";
}
亲自试一试 »

定义和用法

closest() 方法在DOM树上搜索与指定CSS选择器匹配的最近元素。它从元素本身开始,然后测试父对象、祖父母等,直到找到匹配项。如果未找到匹配项,此方法将返回 null


浏览器支持

表中的数字表示支持该方法的第一个浏览器版本。

selectors 必需。指定一个或多个CSS选择器以匹配元素。它们用于根据id、类、类型、属性、属性值等选择HTML元素。

对于多个选择器,请用逗号分隔每个选择器。返回的元素取决于最先在文档中找到的元素。
