推荐答案

如果我查看此列表:

If I look at this list: https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/relatedTarget blur isn't included as having a standard secondary target. So I assume the secondary target on blur in chrome is non-standard.

如果您将模糊替换为focusin或focusout，那么它对我来说也适用于IE11.

If you replace blur by focusin or focusout, it also works for IE11 for me.
