多行显示“...”,一般可以通过css方法实现,也可以通过js方法实现
像截图中的效果,肯定是通过js方法实现的。当超过一定字数后,截取文本,加上“...”就行

额外介绍css方法实现,
单行:

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

多行(部分浏览器有兼容性问题):

display:-webkit-box;
overflow:hidden;
text-overflow:ellipsis;
-webkit-line-clamp:2; // 控制显示行数
-webkit-box-orient:vertical;
