問題描述

我無法弄清楚如何根據懸停在哪個鏈接上來更改文本框的內容.我可以讓它與最接近 div 的任何一個一起工作，但其他鏈接似乎沒有效果.但是，我不想在鏈接之間插入文本，也不想創建多個文本框.我的主要目標是讓鏈接始終位于同一個位置，當您將鼠標懸停在它們上方時，下方的文本框將顯示正確的內容.

I am having trouble trying to figure out how I can make a text box change content depending on what link is being hovered over. I can get it to work with which ever one is closest to the div but the other links seem to have no effect. I do not however want to have text being inserted in between the links nor do I want to create several text boxes. My main goal is to have the links always in the same place and when you hover over them a text box underneath will display the correct content.

這里有一些代碼和一個 JSFiddle 我放在一起幫助更好地說明我的問題:JSFiddle

Here is some code and a JSFiddle I threw together to help better illustrate my question: JSFiddle

HTML:

<a class="one" href="#">one</a>
<a class="two" href="#">two</a>
<a class="three" href="#">three</a>

<div class="element">hello</div>

CSS:

.element {
     display: none;
}

a:hover + .element {
     display: block;
}

推薦答案

您需要以下 HTML 標記:

You need the follwing HTML mark-up:

<a href="#" class="a-1">one</a>
<a href="#"class="a-2">two</a>
<a href="#"class="a-3">three</a>

<div class="element-1">hello one</div>
<div class="element-2">hello two</div>
<div class="element-3">hello three</div>

然后應用以下 CSS:

and then apply the following CSS:

.element-1, .element-2, .element-3{
     display: none;
}
.a-1:hover  ~ .element-1 {
     display: block;
}
.a-2:hover  ~ .element-2{
     display: block;
}
.a-3:hover  ~ .element-3 {
     display: block;
}

CSS 略有重復，但可以正常工作，不需要 JavaScript.

The CSS is slightly repetitive but it works and no JavaScript required.

需要兄弟組合符 (~) 來挑選兄弟元素，請參閱參考.

The sibling combinator (~) is needed to pick out sibling elements, see reference.
