在JavaScript中删除多个换行符(\ n) [英] Remove multiple line breaks (\n) in JavaScript

问题描述

我们为新员工提供了一份入职表格，其中需要删除多个换行符(每行之间4-5个).我想摆脱多余的换行符，但仍将空格与\ n隔开.

We have an onboarding form for new employees with multiple newlines (4-5 between lines) that need stripped. I want to get rid of the extra newlines but still space out the blocks with one \n.

示例:

New employee<br/>
John Doe

Employee Number<br/>
1234

我目前正在使用text = text.replace(/(\r\n|\r|\n)+/g, '$1');，但是它消除了所有没有空格的换行符.

I'm currently using text = text.replace(/(\r\n|\r|\n)+/g, '$1'); but that gets rid of all newlines without spacing.

推荐答案

text = text.replace(/(\r\n|\r|\n){2,}/g, '$1\n');

使用此选项，它将删除至少有2个或更多的换行符.

use this, it will remove newlines where there are at least 2 or more

更新

根据OP的特定要求，我将对答案进行一点编辑.

on specific requirement of the OP I will edit the answer a bit.

text = text.replace(/(\r\n|\r|\n){2}/g, '$1').replace(/(\r\n|\r|\n){3,}/g, '$1\n');
