You can see in the source a whole solution using Javascript and CSS. But if you want labels "look" like disabled you can use CSS this way:
您可以在源代码中看到使用 Javascript 和 CSS 的完整解决方案。但是如果你想让标签“看起来”像被禁用，你可以这样使用 CSS：
In HTML
在 HTML 中
<label class="disabled" for="u">username1 </label>
In CSS
在 CSS 中
label.disabled { color: #aaa; }

Before looking at your example, I would have said:
在看你的例子之前，我会说：
A label can't be disabled. One of the effects it has is to extend the click target of a form control, so you probably want to disable the form control instead.
无法禁用标签。它的作用之一是扩展表单控件的单击目标，因此您可能希望禁用表单控件。
However, for some reason, all your labels are associated with the same control (the one with id="u"), which suggests that you aren't using <label>correctly. It is possible to have multiple labels for a single control, but it doesn't look like you are doing that.
但是，出于某种原因，您的所有标签都与同一个控件（带有 的控件id="u"）相关联，这表明您没有<label>正确使用。单个控件可以有多个标签，但看起来您并没有这样做。
You should probably take a step back and describe the problem that you think disabling a label will solve.
您可能应该退后一步，描述您认为禁用标签可以解决的问题。

You, cant disable the Labels. Instead u can set the Text property of the label to ""when one label is clicked for the other ones.
你，不能禁用标签。相反，您可以将标签的 Text 属性设置""为单击另一个标签的时间。
