假设我们有一个包含一些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,该函数接受一个这样的字符串,并在字符串中每个大写字母之前的空格之前插入一个逗号'。
为此的代码将是-
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
