HTML

<div id="dash">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin nisi ligula, dapibus a volutpat sit amet, mattis et dui. Nunc porttitor accumsan orci id luctus. Phasellus ipsum metus, tincidunt non rhoncus id, dictum a lectus. Nam sed ipsum a urna ac
quam.</p>
</div>

jQuery

var p = $('#dash p');
var ks = $('#dash').height();
while ($(p).outerHeight() > ks) {
  $(p).text(function(index, text) {
    return text.replace(/\W*\s(\S)*$/, '...');
  });
}

CSS

#dash {
  width: 400px;
  height: 60px;
  overflow: hidden;
}

#dash p {
  padding: 10px;
  margin: 0;
}

结果

Lorem ipsum dolor sit amet， consectetur adipiscing elit.Proin nisi Ligula， dapibus a volutpat sit amet， mattis et...

您总是可以通过设置max-width和溢出省略号来使用截断方法

p {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  max-width: 200px;
}

一个例子:

.wrapper { padding: 20px; background: #eaeaea; max-width: 400px; margin: 50px auto; } .demo-1 { overflow: hidden; display: -webkit-box; -webkit-line-clamp: 3; -webkit-box-orient: vertical; } .demo-2 { overflow: hidden; white-space: nowrap; text-overflow: ellipsis; max-width: 150px; } <div class="wrapper"> <p class="demo-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p> </div> <div class="wrapper"> <p class="demo-2">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p> </div>

对于多行截断，请查看flex解决方案。 一个截断3行的示例。

p {
  overflow: hidden;
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
}

一个例子:

p { 空白：无换行; 溢出：隐藏; 文本溢出：省略号; 最大宽度：200px; } <p>Lorem ipsum dolor sit amet， consectetur adipisicing elit.Deserunt rem odit quis quaerat.In dolorem praesentium velit ea esse consequuntur fugit sequi voluptas ut possimus voluptatibus deserunt nisi eveniet！</p>

示例代码:

.limited-text { 空白:nowrap;} 宽度:400 px; 溢出:隐藏; 文本溢出:省略; ｝ <p class="limited-text">我爱你，我爱你。时间和欲望是错误的，是腐败的，是幸福的!</p> .</p

用两种不同的方法试试我的解决方案。

<div class="wrapper">
      <p class="demo-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p>
</div>

<div class="wrapper">
  <p class="demo-2">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p>
</div>

.wrapper {
  padding: 20px;
  background: #eaeaea;
  max-width: 400px;
  margin: 50px auto;
}

.demo-1 {
  overflow: hidden;
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
}

.demo-2 {
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
  max-width: 150px;
}

75个字符

我已经尝试了最大宽度，但这打乱了我的布局。

使用max-width: 75ch，然后创建一个布局，当你超过这个宽度时不会乱。
