截断文本以适合 3 行并在 Html 中显示三个点

Question

我需要将文本显示为段落，但只显示三行并在段落末尾添加 ...（三个点）时截断测试。

Answer 1

Calculate max length of string which can fit into 3 lines and use the following script

var maxLength = 140;
var result = yourString.substring(0, maxLength) + '...';

Answer 2

I use the same logic than @zavg with some improvements:

• Use the single … character.
• Respect the maximum size.

 function truncate(source, size) { return source.length > size ? source.slice(0, size - 1) + "…" : source; } var res = truncate('Truncate text to fit in 3 lines', 14); console.log(res);

 .class-name { display: block; white-space: nowrap; width: 15em; overflow: hidden; text-overflow: ellipsis; }
