Element.getAttributeNames() - Web API 接口参考 编辑

Element.getAttributeNames() 返回一个Array，该数组包含指定元素（Element）的所有属性名称，如果该元素不包含任何属性，则返回一个空数组。

将 getAttributeNames() 与 getAttribute() 组合使用， 是一种有效替代 Element.attributes 的使用方法.

语法

let attributeNames = element.getAttributeNames();

例子

// 遍历elements的元素
for(let name of element.getAttributeNames())
{
	let value = element.getAttribute(name);
	console.log(name, value);
}
