在CSS中，使用“…”表示多行溢出块

with

overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;

如果溢出，“…”将显示在行末。但是，这将只在一行中显示。但我希望它能多行显示。

它可能看起来像:

+--------------------+
|abcde feg hij   dkjd|
|dsji jdia js ajid  s|
|jdis ajid dheu d ...|/*Here it's overflowed, so "..." is shown. */
+--------------------+

Javascript解决方案将更好

获取文本的行数如果窗口调整大小或元素更改，则切换is-省略号类

getRowRects

getclientrects()是这样工作的

同一行中的每个矩形都有相同的顶部值，所以找出顶部值不同的矩形，就像这样

function getRowRects(element) {
    var rects = [],
        clientRects = element.getClientRects(),
        len = clientRects.length,
        clientRect, top, rectsLen, rect, i;

    for(i=0; i<len; i++) {
        has = false;
        rectsLen = rects.length;
        clientRect = clientRects[i];
        top = clientRect.top;
        while(rectsLen--) {
            rect = rects[rectsLen];
            if (rect.top == top) {
                has = true;
                break;
            }
        }
        if(has) {
            rect.right = rect.right > clientRect.right ? rect.right : clientRect.right;
            rect.width = rect.right - rect.left;
        }
        else {
            rects.push({
                top: clientRect.top,
                right: clientRect.right,
                bottom: clientRect.bottom,
                left: clientRect.left,
                width: clientRect.width,
                height: clientRect.height
            });
        }
    }
    return rects;
}

也有几个jquery插件处理这个问题，但许多不处理多行文本。以下工作:

还有一些性能测试。

我发现这个css (scss)解决方案的工作相当好。在webkit浏览器上，它显示省略号，而在其他浏览器上，它只是截断文本。这对我的预期用途很好。

$font-size: 26px;
$line-height: 1.4;
$lines-to-show: 3;

h2 {
  display: block; /* Fallback for non-webkit */
  display: -webkit-box;
  max-width: 400px;
  height: $font-size*$line-height*$lines-to-show; /* Fallback for non-webkit */
  margin: 0 auto;
  font-size: $font-size;
  line-height: $line-height;
  -webkit-line-clamp: $lines-to-show;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

好问题……我希望有一个答案，但这是最近你能得到的CSS。没有省略，但仍然很好用。

overflow: hidden;
line-height: 1.2em;
height: 3.6em;      // 3 lines * line-height

有点晚了，但我想到了，我认为，是一个独特的解决方案。而不是试图通过css技巧或js插入自己的省略号，我想我会试着使用单行限制。所以我复制了每个“行”的文本，只是使用负文本缩进，以确保一行从最后一行停止的地方开始。小提琴

CSS:

#wrapper{
    font-size: 20pt;
    line-height: 22pt;
    width: 100%;
    overflow: hidden;
    padding: 0;
    margin: 0;
}

.text-block-line{
    height: 22pt;
    display: inline-block;
    max-width: 100%;
    overflow: hidden;
    white-space: nowrap;
    width: auto;
}
.text-block-line:last-child{
    text-overflow: ellipsis;
}

/*the follwing is suboptimal but neccesary I think. I'd probably just make a sass mixin that I can feed a max number of lines to and have them avialable. Number of lines will need to be controlled by server or client template which is no worse than doing a character count clip server side now. */
.line2{
    text-indent: -100%;
}
.line3{
    text-indent: -200%;
}
.line4{
    text-indent: -300%;
}

HTML:

<p id="wrapper" class="redraw">
    <span class="text-block-line line1">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line2">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line3">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line4">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
</p>

更多的细节在小提琴。有一个问题与浏览器回流，我使用JS重绘，这样做检查它，但这是基本概念。任何想法/建议都非常感谢。
