text-overflow: ellipsis;

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. */
+--------------------+
基于-webkit-line-clamp的纯CSS方法:
@-webkit-keyframes ellipsis {/*for test*/
0% { width: 622px }
50% { width: 311px }
100% { width: 622px }
}
.ellipsis {
max-height: 40px;/* h*n */
overflow: hidden;
background: #eee;
-webkit-animation: ellipsis ease 5s infinite;/*for test*/
/**
overflow: visible;
/**/
}
.ellipsis .content {
position: relative;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-box-pack: center;
font-size: 50px;/* w */
line-height: 20px;/* line-height h */
color: transparent;
-webkit-line-clamp: 2;/* max row number n */
vertical-align: top;
}
.ellipsis .text {
display: inline;
vertical-align: top;
font-size: 14px;
color: #000;
}
.ellipsis .overlay {
position: absolute;
top: 0;
left: 50%;
width: 100%;
height: 100%;
overflow: hidden;
/**

.ellipsis .overlay:before {

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;
}

谢谢@balpha和@Kevin,我把两种方法结合在一起。
这个方法不需要js。
你可以使用背景图像和不需要梯度隐藏点。
.ellipsis-placeholder的innerHTML不是必需的,我使用.ellipsis-placeholder来保持与.ellipsis-more相同的宽度和高度。
你可以使用display: inline-block代替。
.ellipsis {
overflow: hidden;
position: relative;
}
.ellipsis-more-top {/*push down .ellipsis-more*/
content: "";
float: left;
width: 5px;
}
.ellipsis-text-container {
float: right;
width: 100%;
margin-left: -5px;
}
.ellipsis-more-container {
float: right;
position: relative;
left: 100%;
width: 5px;
margin-left: -5px;
border-right: solid 5px transparent;
white-space: nowrap;
}
.ellipsis-placeholder {/*keep text around ,keep it transparent ,keep same width and height as .ellipsis-more*/
float: right;
clear: right;
color: transparent;
}
.ellipsis-placeholder-top {/*push down .ellipsis-placeholder*/
float: right;
width: 0;
}
.ellipsis-more {/*ellipsis things here*/
float: right;
}
.ellipsis-height {/*the total height*/
height: 3.6em;
}
.ellipsis-line-height {/*the line-height*/
line-height: 1.2;
}
.ellipsis-margin-top {/*one line height*/
margin-top: -1.2em;
}
.ellipsis-text {
word-break: break-all;
}
