优点: +跨浏览器(IE11, Edge, Chrome, Firefox, Safari等) +最自然的外观

缺点: -为DOM添加了很多额外的元素

我对我见过的所有变通办法都不满意。他们大多数使用线钳，目前只支持在webkit。所以我一直在研究，直到我想出了一个解决方案。这个纯javascript解决方案应该与IE10和更高版本以及所有现代浏览器兼容。在下面的stackoverflow示例空间之外，这是未经测试的。

我认为这是一个很好的解决方案。一个重要的警告是，它为容器内的每个单词创建了一个跨度，这将影响布局性能，因此您的里程可能会有所不同。

//This is designed to be run on page load, but if you wanted you could put all of this in a function and addEventListener and call it whenever the container is resized. var $container = document.querySelector('.ellipses-container'); //optional - show the full text on hover with a simple title attribute $container.title = $container.textContent.trim(); $container.textContent.trim().split(' ').some(function (word) { //create a span for each word and append it to the container var newWordSpan = document.createElement('span'); newWordSpan.textContent = word; $container.appendChild(newWordSpan); if (newWordSpan.getBoundingClientRect().bottom > $container.getBoundingClientRect().bottom) { //it gets into this block for the first element that has part of itself below the bottom of the container //get the last visible element var containerChildNodes = $container.childNodes; var lastVisibleElement = containerChildNodes[containerChildNodes.length - 2]; //replace this final span with the ellipsis character newWordSpan.textContent = '\u2026'; //if the last visible word ended very near the end of the line the ellipsis will have wrapped to the next line, so we need to remove letters from the last visible word while (lastVisibleElement.textContent != "" && newWordSpan.getBoundingClientRect().bottom > $container.getBoundingClientRect().bottom) { lastVisibleElement.style.marginRight = 0; lastVisibleElement.textContent = lastVisibleElement.textContent.slice(0, -1); } //using .some() so that we can short circuit at this point and no more spans will be added return true; } }); .multi-line-container { border: 1px solid lightgrey; padding: 4px; height: 150px; width: 300px; } .ellipses-container { display: inline-flex; flex-wrap: wrap; justify-content: flex-start; align-content: flex-start; /* optionally use align-content:stretch, the default, if you don't like the extra space at the bottom of the box if there's a half-line gap */ overflow: hidden; position: relative; } .ellipses-container > span { flex: 0 0 auto; margin-right: .25em; } .text-body { display: none; } <div class="multi-line-container ellipses-container"> <div class="text-body ellipses-text">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque luctus ut massa eget porttitor. Nulla a eros sit amet ex scelerisque iaculis nec vitae turpis. Sed pharetra tincidunt ante, in mollis turpis consectetur at. Praesent venenatis pulvinar lectus, at tincidunt nunc finibus non. Duis tortor lectus, elementum faucibus bibendum vitae, egestas bibendum ex. Maecenas vitae augue vitae dui condimentum imperdiet sit amet mattis quam. Duis eleifend scelerisque magna sed imperdiet. Mauris tempus rutrum metus, a ullamcorper erat fringilla a. Suspendisse potenti. Praesent et mi enim. Orci varius natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. </div> </div>

<div>
     <p class="cards-values">Lorem ipsum dolor sit amet,   consectetur adipiscing elit. Nunc aliquet lorem commodo, semper mauris nec, suscipit nisi. Nullam laoreet massa sit amet leo malesuada imperdiet eu a augue. Sed ac diam quis ante congue volutpat non vitae sem. Vivamus a felis id dui aliquam tempus
      </p>
      <span class="tooltip"></span>
</div>

这个人有最好的解决办法。css:

.multiline-ellipsis {
    display: block;
    display: -webkit-box;
    max-width: 400px;
    height: 109.2px;
    margin: 0 auto;
    font-size: 26px;
    line-height: 1.4;
    -webkit-line-clamp: 3;
    -webkit-box-orient: vertical;
    overflow: hidden;
    text-overflow: ellipsis;
}

如果你正在使用javascript，也许你可以像下面这样做。 然而，这并没有考虑到集装箱的高度…

// whatever string const myString = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum pellentesque sem ut consequat pulvinar. Curabitur vehicula quam sit amet risus aliquet, sed rhoncus tortor fermentum. Etiam ac fermentum nisi. Ut in lobortis eros. Etiam urna felis, interdum sit amet fringilla eu, bibendum et nunc.'; // you can set max string length const maxStrLength = 100; const truncatedString = myString.length > maxStrLength ? `${myString.substring(0, maxStrLength)}...` : myString; console.log(truncatedString);

p{
line-height: 20px;
width: 157px;
white-space: nowrap; 
overflow: hidden;
text-overflow: ellipsis;
}

或者我们可以通过使用和高度和溢出来限制行。

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。
