字符串替换

democode

ts

import { strReplace } from 'one-js-utils-library';
strReplace('12345678910', 4, 4, '*'); // 1234****910

ts

const strReplace = (
  str: string,
  startIndex: number,
  length: number,
  replacement: string,
): string => {
  const prefix = str.slice(0, startIndex);
  const suffix = str.slice(startIndex + length);
  const masked = replacement.repeat(length);
  return `${prefix}${masked}${suffix}`;
};

\n 转换为 <br>

democode

ts

import { n2br } from 'one-js-utils-library';
const result = n2br('Hello\nWorld'); // Hello<br/>World

ts

const n2br = (str: string) => {
  const t = str.replace(/\n/g, '<br/>');
  return t;
};
