Underlining in Javascript?
提问by Code Monkey
Upon the realization that you can't have an inline pseudoclass -- How to write a:hover in inline CSS?-- I looked into having Javascript do the same job with the onMouseOver
and onMouseOut
events to simulate the :hover
pseudoclass. I'm trying to remove the underline from the text when the mouse is above it. Is there a snippet of Javascript someone can offer that can do that?
意识到您不能拥有内联伪类后——如何在内联 CSS 中编写 a:hover?-- 我研究让 Javascript 对onMouseOver
和onMouseOut
事件做同样的工作来模拟:hover
伪类。当鼠标位于文本上方时,我试图从文本中删除下划线。有人可以提供可以做到这一点的Javascript片段吗?
I tried onMouseOver="this.style.textDecoration="none""
, but I think the contrasting quotations are throwing everything off.
我试过了onMouseOver="this.style.textDecoration="none""
,但我认为对比鲜明的引语把一切都抛在了脑后。
Any ideas?
有任何想法吗?
Note: unfortunately, this effect must be achieved without the use of an external or internal stylesheet (inline only).
注意:不幸的是,这种效果必须在不使用外部或内部样式表(仅限内联)的情况下实现。

Here's your answer:
这是你的答案:
<a onmouseover="this.style.textDecoration='none';" onmouseout="this.style.textDecoration='underline';">hover me</a>
if you're able to use jQuery it would be easier. Just write once the following code. You haven't to change your markup then.
如果您能够使用 jQuery,那就更容易了。只需编写一次以下代码。那么您不必更改标记。
<script type="text/javascript">
(function($) {
$( function() {
$('a').hover(
function() {
$(this).css('text-decoration','none');
},
function() {
$(this).css('text-decoration','underline');
}
)
} );
} (jQuery));
</script>

I think you shouldn't use javascript, but CSS:
我认为你不应该使用 javascript,而是使用 CSS:
.underlineHover:hover {
text-decoration: underline;
}
<span class="underlineHover">Content</span>
Note: I used the class underlineHover
, but be aware that classes should have a semantic meaning instead of styling one.
注意:我使用了 class underlineHover
,但请注意, classes 应该具有语义而不是样式。
