我最近创建了一个按钮，当用户在按钮上滚动时，它会显示一个带有文本的黑色弹出框(在按钮本身之外)。我希望在单击按钮而不是悬停时显示该框，并且一旦用户再次单击该按钮，该框就会消失。有人告诉我这不能用 CSS 完成，我必须使用 JavaScript。请帮助。谢谢!下面是按钮当前如何工作的 fiddle 链接。 http://jsfiddle.net/44hx4/2/

最佳答案
你可以像这样用 jQuery 试试 Fiddle
$(function(){
$("#Image10").click(function(){
$(".imgDescription").toggleClass("show");
});
});
虽然我个人会更改为切换显示而不是像这个 Fiddle 中那样的可见性
