我正在尝试这样做，以便在按下按钮时显示相应的 DIV 元素。一旦单击一个按钮，就会出现一排按钮，div 元素应显示与按钮相关的文本。

这是我到目前为止所拥有的：

<div id="info_5" style="display:none">Emporium Text</div>
<div id="info_6" style="display:none">Pacifica Text</div>
</body>
</html>

为什么这不起作用？

谢谢你的帮助。

您将以下值发送到“切换”功能：

toggle('1'); // '1'

Javascript 将此值作为字符串获取，但您在不使用单引号 (') 的情况下对其进行检查。

但本质上是，您使用的是单个“相等”而不是两个。它必须看起来像：

if (vals == '6' ) { /* Do something */ }

如果您只使用一个 = ，则该语句始终返回“true”，因为变量“vals”的值是“6”。如果此操作成功（始终成功），则返回“true”...

In generel you're script looks like very complicated for a simple taks. You should take a look to librarys like jQuery with built-in functions like toggle(), slidetoggle(), fadetoggle() and other ready-to-use functions :-) ... Try the examples here: http://api.jquery.com/slideToggle/
