如何使用 JavaScript 在给定句子中查找大写单词并在大写单词前添加一个字符?
假设,我们有一个包含大写英文字母的字符串,如下所示:
const str = "Connecting to server Connection has been successful We found result";
我们需要编写一个 JavaScript 函数,此函数可以获取一个这样的字符串,并在每个大写字母前的空格前插入一个逗号“,”。
代码如下:
const str = "Connecting to server Connection has been successful We found result"; const capitaliseNew = str => { let newStr = ''; const regex = new RegExp(/.[A-Z]/g); newStr = str.replace(regex, ',$&'); return newStr; }; console.log(capitaliseNew(str));
以下是控制台上的输出:
Connecting to server, Connection has been successful, We found result
