对多行文本应用省略号

是否有一个解决方案，添加省略号内的最后一行与流体高度(20%)div ?

我在CSS中找到了-webkit-线夹函数，但在我的情况下，行号将取决于窗口大小。

p { width:100%; height:20%; background:red; position:absolute; } <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla sed dui felis. Vivamus vitae pharetra nisl, eget fringilla elit. Ut nec est sapien. Aliquam dignissim velit sed nunc imperdiet cursus. Proin arcu diam, tempus ac vehicula a, dictum quis nibh. Maecenas vitae quam ac mi venenatis vulputate. Suspendisse fermentum suscipit eros, ac ultricies leo sagittis quis. Nunc sollicitudin lorem eget eros eleifend facilisis. Quisque bibendum sem at bibendum suscipit. Nam id tellus mi. Mauris vestibulum, eros ac ultrices lacinia, justo est faucibus ipsum, sed sollicitudin sapien odio sed est. In massa ipsum, bibendum quis lorem et, volutpat ultricies nisi. Maecenas scelerisque sodales ipsum a hendreritLorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla sed dui felis. Vivamus vitae pharetra nisl, eget fringilla elit. Ut nec est sapien.

糟糕的CSS不支持跨浏览器多行夹紧，只有webkit似乎在推动它。

你可以尝试使用一个简单的Javascript省略号库，比如github上的Ellipsity，源代码非常干净和小，所以如果你确实需要做任何额外的改变，它应该很容易。

经过多次尝试，我终于用混合的js / css来处理多行和单行溢出。

CSS3代码:

.forcewrap { // single line ellipsis
  -ms-text-overflow: ellipsis;
  -o-text-overflow: ellipsis;
  text-overflow: ellipsis;
  overflow: hidden;
  -moz-binding: url( 'bindings.xml#ellipsis' );
  white-space: nowrap;
  display: block;
  max-width: 95%; // spare space for ellipsis
}

.forcewrap.multiline {
  line-height: 1.2em;  // my line spacing 
  max-height: 3.6em;   // 3 lines
  white-space: normal;
}

.manual-ellipsis:after {
  content: "\02026";      // '...'
  position: absolute;     // parent container must be position: relative
  right: 10px;            // typical padding around my text
  bottom: 10px;           // same reason as above
  padding-left: 5px;      // spare some space before ellipsis
  background-color: #fff; // hide text behind
}

我简单地检查js代码的溢出在divs，像这样:

function handleMultilineOverflow(div) {
    // get actual element that is overflowing, an anchor 'a' in my case
    var element = $(div).find('a'); 
    // don't know why but must get scrollHeight by jquery for anchors
    if ($(element).innerHeight() < $(element).prop('scrollHeight')) {
        $(element).addClass('manual-ellipsis');
    }
}

html中的用法示例:

<div class="towrap">
  <h4>
    <a class="forcewrap multiline" href="/some/ref">Very long text</a>
  </h4>
</div>

在浏览了整个互联网并尝试了很多这些选项后，唯一能确保它正确覆盖支持i.e.的方法是通过javascript，我创建了一个循环函数来查看需要多行截断的post项目。

*注意我使用Jquery，并要求你的post__items类有一个固定的最大高度。

// loop over post items
$('.post__items').each(function(){
    var textArray = $(this).text().split(' ');
    while($(this).prop('scrollHeight') > $(this).prop('offsetHeight')) {
        textArray.pop();
        $(this).text(textArray.join(' ') + '...');
     }
});

我在YouTube的主页上看了一下它是如何解决这个问题的，并进行了简化:

.multine-ellipsis {
  -webkit-box-orient: vertical;
  display: -webkit-box;
  -webkit-line-clamp: 2;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: normal;
}

这将允许2行代码，然后附加一个省略号。

你可以使用CSS3中的线夹函数。

p {
    overflow: hidden;
    text-overflow: ellipsis;
    display: -webkit-box;
    line-height: 25px;
    height: 52px;
    max-height: 52px;
    font-size: 22px;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;
}

确保你像改变自己的设置一样改变设置。
