Javascript导致div在两个类之间交替出现
我有一个函数,通过使用JS设置类名来移动方框。问题是,不知何故,在正确的时间设置了正确的类,但是div在原始类和新类之间交替…每秒钟一次。我将尝试在这里发布小提琴链接。页面上有四个框,单击其中一个成功地将其他三个框向左转换,然后展开所选框。这部分很好用。问题是当我单击一个左框时,四个选项中的一个已展开。扩展后的类开始转换到新类,然后开始返回到扩展后的位置。。。然后永远来回。我尝试过清除div中的所有类,然后进行翻译。我相信JS有一个设计规则我没有?我尝试过的任何东西都不能改变阶级斗争 HTML:Javascript导致div在两个类之间交替出现,javascript,css,html,Javascript,Css,Html,我有一个函数,通过使用JS设置类名来移动方框。问题是,不知何故,在正确的时间设置了正确的类,但是div在原始类和新类之间交替…每秒钟一次。我将尝试在这里发布小提琴链接。页面上有四个框,单击其中一个成功地将其他三个框向左转换,然后展开所选框。这部分很好用。问题是当我单击一个左框时,四个选项中的一个已展开。扩展后的类开始转换到新类,然后开始返回到扩展后的位置。。。然后永远来回。我尝试过清除div中的所有类,然后进行翻译。我相信JS有一个设计规则我没有?我尝试过的任何东西都不能改变阶级斗争 HTML:

您可以通过将
setInterval
方法更改为setTimeout
来获得所需的功能,如本演示所示-。这将只执行一次函数,而不是每秒重复调用它们
但是你肯定可以改进你的代码更多
更新
我认为您可以将代码缩短为如下所示。检查演示-
和标记

双倍行距实际上对眼睛更难,这就是问题所在。非常感谢。除了每个人都很快指出的缩进编辑之外,您还将如何改进它?我对JavaScript不太了解。嗨!我更新了答案,提出了一些如何改进代码的想法
