You were close, to test for focus:
你很接近，测试焦点：
$('a').is(':focus');
Not sure about how to get the last focused element, you may have to design a hack for it...something like:
不确定如何获得最后一个焦点元素，您可能需要为它设计一个 hack ......类似于：
var lastFocusedClass;
$(document).on('focus', '*', function() {
lastFocusedClass = $(this).attr("class");
});
回答by Anand Singh
In my case this works... $("*:focus")
在我的情况下，这有效...... $("*:focus")
You can get id,name,valueetc.And check if this is the element you are looking for.
你可以得到id，name，value等二十多个国家检查，如果这是你正在寻找的元素。
var checkValue = $("*:focus").attr("...");
