在 HTML 中，我有以下单选按钮选项

In HTML, I have the following radio button choices

o 选择 1 o 选择 2 o 选择 3

o Choice 1 o Choice 2 o Choice 3

我想要做的是，当有人从上方选择一个单选按钮时，与所选单选按钮对应的文本变为粗体.

What I would like to do is when someone SELECTs a radio button from above, that the text corresponding to that radio button selected becomes bold.

因此，例如 - 如果该人选择选择 2"，则单选按钮选择现在看起来像:

So, for example - if the person selects "Choice 2", the radio button selection would now look like:

o 选择 1 o 选择 2 o 选择 3

o Choice 1 o Choice 2 o Choice 3

我该怎么做?我假设必须使用 JavaScript 或 CSS.

How do I do this? I assume either JavaScript or CSS has to be used.

更新:如果不使用 jQuery，你将如何实现nickf"解决方案?

推荐答案

你可以纯粹用 CSS 来做到这一点，但你需要将每个输入的文本包装在 span 或其他标签中:

You can do this purely with CSS, but you need to wrap the text of each input in a span or other tag:

<input type="radio" name="group1" value="Milk"><span>Milk</span><br>

然后只使用兄弟选择器:

Then just use the sibling selector:

input[type="radio"]:checked+span { font-weight: bold; }
