Pet*_*ter 448 css text overflow ellipsis
是否可以使用CSS将文本长度限制为"n"行(或者在垂直溢出时将其剪切).
text-overflow: ellipsis; 仅适用于1行文本.
原文:
Ultrices natoque mus mattis,aliquam,cras in pellentesque tincidunt
elit purus lectus,vel ut aliquet,elementum
nunc nunc rhoncus placerat urna!坐下来看看!Ut penatibus turpis
mus tincidunt!Dapibus sed aenean,magna sagittis,lorem velit
想要输出(2行):
Ultrices natoque mus mattis,aliquam,cras in pellentesque
tincidunt elit purus lectus,vel ut aliquet,elementum ...

有一种方法,但它只是webkit.但是,当你将它与它结合使用line-height: X;时max-height: X*N;,它也可以在其他浏览器中使用,只是没有省略号.
.giveMeEllipsis {
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: N; /* number of lines to show */
line-height: X; /* fallback */
max-height: X*N; /* fallback */
}

你能做的是以下几点:
.max-lines {
display: block; /* or inline-block */
text-overflow: ellipsis;
word-wrap: break-word;
overflow: hidden;
max-height: 3.6em;
line-height: 1.8em;
}

其中max-height:= line-height:× <number-of-lines>in em.

使用跨浏览器解决方案
多年来这个问题困扰着我们所有人......
为了在所有情况下提供帮助,我已经列出了仅CSS的方法,以及一个jQuery方法,以防css警告出现问题.
这是我提出的CSS解决方案,适用于所有情况,但有一些小问题.
基础很简单,它隐藏了跨度的溢出,并根据Eugene Xa建议的线高设置最大高度.
然后在包含div之后有一个伪类,它可以很好地放置省略号.
注意事项
无论是否需要,此解决方案将始终放置省略号.
如果最后一行以结尾句结束,那么最终会得到四个点....
您需要对合理的文本对齐感到满意.
省略号将位于文本的右侧,看起来很草率.

jQuery方法
在我看来,这是最好的解决方案,但不是每个人都可以使用JS.基本上,jQuery将检查任何.text元素,如果有比预设的max var更多的字符,它将关闭其余部分并添加省略号.
这种方法没有任何警告,但是这个代码示例仅用于演示基本思想 - 我不会在生产中使用它而不改进它有两个原因:
1)它将重写.text elems的内部html.是否需要.2)没有测试检查内部html没有嵌套元素 - 所以你很依赖作者正确使用.text.

Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight.

据我所知,这只有可能使用height: (some em value); overflow: hidden,即便如此,它最终也不会有幻想....
如果这不是一个选项,我认为没有一些服务器端预处理(很难,因为文本流不可能无法可靠地预测)或jQuery(可能但可能复杂)是不可能的.

我有一个运行良好的解决方案,但它使用渐变代替省略号。当您有动态文本时它会起作用,因此您不知道它是否足够长以需要椭圆。优点是您不必进行任何 JavaScript 计算,它适用于包括表格单元格在内的可变宽度容器,并且是跨浏览器的。它使用了几个额外的 div,但它很容易实现。
