哪种方法更正确地获取文档中具有焦点的元素？

我已经询问了几个与此相关的问题，并且发现了两种常见的方法。

拥有全局元素，并通过将 onFocus() 事件附加到每个元素来更新它。

document.activeElement 并使用以下代码来更新元素，以防旧浏览器不支持该属性

var focusElement;
document.addEventListener("焦点", 函数(e) {
    focusElement = e.target;
}， 真的）;
document.addEventListener("模糊", 函数(e) {
    焦点元素 = null;
}， 真的）;

现在我的问题是上述两种方法中哪一种更正确/简单/高效？为什么？谢谢大家，

I have went through couple of questions already asked related with this and i have found two common approach.

Have global element and update it by attaching onFocus() event to each of the element.

document.activeElement and have following code to update the element in case of old browser which do not support the property

var focusedElement;
document.addEventListener("focus", function(e) {
    focusedElement = e.target;
}, true);
document.addEventListener("blur", function(e) {
    focusedElement = null;
}, true);

Now my question is which one is more correct/easy/efficient approach of above two? why?
Thanks all,
