我想从打字稿中的字符串中获取以 $ 开头的单词（标记）

Question

如下例，我想使用打字稿从字符串中获取标记：

var str = "Hello $FirstName $LastName, Your account with number $AccountNumber will activate soon".

预期结果：

数组：["$FirstName","$LastName","$AccountNumber"]

或逗号分隔的字符串：var commaSepData = "$FirstName,$LastName,$AccountNumber";

Answer 1

使用

var str = "Hello $FirstName $LastName, Your account with number $AccountNumber will activate soon";

res = str.split(' ').filter( chunk => chunk.includes('$'))

//res = ["$FirstName", "$LastName,", "$AccountNumber"]

Answer 2

另一种方法是使用正则表达式：

const str = "Hello $FirstName $LastName, Your account with number $AccountNumber will activate soon";
const groups = str.match(/($\w+)/g);
console.log(groups);
