Question

我在将DIV的“q4”，“q5”，“q6”和“q7”连接到正确的位置时遇到问题。我希望q4显示何时单击平板电脑，q5显示何时单击Macbook，q6显示何时单击Mac，以及q7显示何时单击iPod。有人可以向我解释一下这是怎么做的吗？我看下面的javascript，我看到一个模式，但如何添加更多按钮？

Answer 1

使用jQuery show / hide方法：

<script>
$("#buttonID").click(function() {
     $(".groupClass").show("fast");
});
</script>

Answer 2

你走了：

我希望q4在点击平板电脑时显示

$('#tablet').click(function(){
$('#q4').show();
});

此处tablet和q4分别是IDs元素（按钮或div）。

同样适用于q5，q6等等，您只需更改IDs即可。我想我的一些老年人之前已经回答了这个问题，但我认为我已经以更明确的方式清除了自己，提问者想要：）

Answer 3

找到了罪魁祸首，你试图调用一个函数来显示第5个元素或第6个元素，但是在函数内部你只检查了4个对象。做了一个小小的纠正，事情应该有效。

以下工作代码：）

<html>

<a href="#" onclick="showHide(1);"><button>iPhone</button></a>

<a href="#" onclick="showHide(3)"><button>iPod</button></a>
<a href="#" onclick="showHide(4);"><button>Tablet</button></a>
<a href="#" onclick="showHide(5);"><button>Macbook</button></a>
<a href="#" onclick="showHide(6)"><button>Mac</button></a>

虽然此代码可以按照您的预期运行，但请记住使用更好的命名约定，例如我在我的示例HERE.中展示的
