推荐答案
您正在使用JavaScript array.find（）方法。请注意，这是标准的JS，与jQuery无关。事实上，你问题中的整个代码根本就不使用jQuery。
You are using the JavaScript array.find() method. Note that this is standard JS, and has nothing to do with jQuery. In fact, your entire code in the question makes no use of jQuery at all.
你可以找到 array.find（）<的文档/ code>此处： https://developer.mozilla.org/ en / docs / Web / JavaScript / Reference / Global_Objects / Array / find
如果滚动到本页底部，你会注意到它有浏览器支持信息，你会看到它声明IE不支持这种方法。
If you scroll to the bottom of this page, you will note that it has browser support info, and you will see that it states that IE does not support this method.
具有讽刺意味的是，你最好的方法是使用jQuery，它确实有所有浏览器都支持类似的功能。
Ironically, your best way around this would be to use jQuery, which does have similar functionality that is supported in all browsers.
