javascript - 在 html 中显示短语的前 4 个单词

Question

我有一个很长的短语，我想显示前 4 个单词。

示例:

The style of this paper is a combination of an external stylesheet, and internal style.

变成这样:

这...的风格

Answer 1

您可以为此使用正则表达式。它取前四个词并添加一些点，

var text = 'The style of this paper is a combination of an external stylesheet, and internal style.';
document.write(text.replace(/^((\w*\W*){0,4}).*/, '$1...'));
