为什么不应在锚点中使用交互式元素? [英] Why should interactive element not be used within an anchor?

问题描述

只是出于好奇 - 我在我之前的问题中因试图将按钮放置在锚定图像中而被钉住了.我查看了文档和其他问题，虽然每个人都说不应该这样做，但他们并没有说明原因.

Simply out of curiosity - I have been nailed in my previous question for trying to put button within an anchored image. I looked at documentations and other questions and although everyone is saying that it should not be done, they are not saying why.

即使是文档 http://www.w3.org/TR/html5/text-level-semantics.html#the-a-element 声明锚内不应该有交互式内容，但没有告诉我推理.

Even the documentation http://www.w3.org/TR/html5/text-level-semantics.html#the-a-element states that there should be no interactive content within anchor, but does not tell me the reasoning.

有谁知道为什么这样做是一种可怕的做法?

Does anyone know why is it such a horrible practice to do so?

推荐答案

想象一下这种情况:

<a href="http://google.com">
  <select>
    <option>V1</option>
    <option>V2</option>
  </select>
</a>

现在，当您按下 select 元素时，这些操作将生效(按顺序):

Now when you press on select element these actions will take effect (in order):

1. 打开选择下拉菜单.
2. 将 click 事件添加到父级(在本例中为 ).
3. 元素跟随它的 href 值(此时您离开当前页面).
4. (经过人体的一些延迟)您将选择所需的选项(但您已经离开了网站)

1. Open select dropdown.
2. Bubble click event to parent (<a> in this case).
3. <a> element follows it's href value (at this point you leave current page).
4. (after some delay by human body) You would select desired option (but you had already left website)
