是“为"如果目标输入嵌套在标签内，则 HTML 标签中必需的属性? [英] Is "for" attribute necessary in HTML label if the target input is nested inside the label?

问题描述

我注意到当您将输入元素放入标签元素时，HTML 标签标签不需要for"属性:

I've noticed that a HTML label tag doesn't need the 'for' attribute when you put your input element into the label element:

<label><input type="text">Last name</label>

但我想知道最好的做法是什么.有人可以帮我吗?

But I was wondering what's the best practise. Can anybody help me with that?

谢谢！
