<div class='divouter'>

回答1:

You could use the $.after() method:

$(".test3").closest(".divouter").after("<div>Foo</div>");

Or the $.insertAfter() method:

$("<div>Foo</div>").insertAfter( $(".test3").closest(".divouter") );

回答2:

.divouter:parent

I think you want the "after()" method:

$('input.test3').focus(function() {
   $(this).closest('div.divouter').after('<div>Hi!</div>');
});
