将标签与class not id的输入关联起来？ [英] Associate label to input with class not id?

问题描述

我知道您可以使用for和id属性将标签与输入相关联。但是，你可以使用一个类而不是一个ID？谢谢

 < label for =rooms>房间数量< / label> 
< select id =rooms> 
< option value =1> 1< / option> 
< option value =2> 2< / option> 
< option value =3> 3< / option> 
< option value =4> 4< / option> 
< / select> 
  

解决方案

类不是唯一的如果您希望将标签与输入相关联而不使用ID，则可以隐式将它分配给包括标签内的输入内容：

 < label>房间数量
 < select name =rooms> 
< option value =1> 1< / option> 
< option value =2> 2< / option> 
< option value =3> 3< / option> 
< option value =4> 4< / option> 
< / select> 
< / label> 
  

I know that you can associate a label with an input using the for and id attributes. However can you use a class and not an id? Thanks

<label for="rooms">Number of rooms</label>
<select id="rooms">
                    <option value="1">1</option>
                    <option value="2">2</option>
                    <option value="3">3</option>
                    <option value="4">4</option>
</select>

解决方案

Classes are not unique (you can have multiple elements with the same class), so no.

If you want to associate a label to an input without using ID, you can implicitly assign it by including said input inside of the label:

<label>Number of rooms
    <select name="rooms">
        <option value="1">1</option>
        <option value="2">2</option>
        <option value="3">3</option>
        <option value="4">4</option>
    </select>
</label>
