Question

寻找一些javascript的更多帮助！我一直在搞乱我已经有的尝试并扩展它，我无法得到任何工作！无论如何让我解释一下！下面将有一个演示，供您查看我在说什么！

我希望能够在单击时更改黑色，黄色或红色方块的背景，并在再次单击时恢复为常规图像，并且我还希望在第二次单击时打开的窗口关闭也！

请帮忙！我知道它与使用.css函数有关，但我无法弄清楚如何做到这一点！顺便说一句，我当前的真实背景图像是一个精灵，所以我不确定这是否会影响任何事情。谢谢！

这是一些代码！

Answer 1

您可以通过以下方式完成此操作：

  $("#onclick").click(function() {
        $("#log").css("display", "block");
    });

和CSS中的#log：

#log{
    opacity:0.92; 
    position: absolute;
    top: 0px;
    left: 0px;
    height: 100%;
    width: 100%;
    background: #000;
    display: none;
}

Answer 2

只需添加一个具有新背景的课程并在其上点击

即可

   $(this).toggleClass('blueBackground');
