我想从打字稿中的字符串中获取单词（令牌）以 $ 开头

Question

如下例所示，我想使用 typescript 从字符串中获取令牌：

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

预期结果：

一个数组： ["$FirstName","$LastName","$AccountNumber"]

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

Answer 1

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);

Answer 2

利用

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

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

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