如何使用 javascript 在字符第 9 次出现后获取文本？

Question

我得到以下字符串： NPA-Woodburn,OR,Woodburn,OR,97071,Bensenville,IL,60106,150.00,0.00,cash/certified funds,enclosed,operable,

我需要遍历一些行并对“,”之后的第 9 个文本求和，但我就是做不到。我见过很多解决方案的组合，但 none 让我明白了。

谢谢。

Answer 1

您可以split the string by that character, remove all items in the array before the 9th item (with slice), then join按字符返回数组。

const character = ",";

const str = "NPA-Woodburn,OR,Woodburn,OR,97071,Bensenville,IL,60106,150.00,0.00,cash/certified funds,,enclosed,operable,,,,,";

const res = str.split(character).slice(9).join(',')
console.log(res)

要隔离第 8 次出现，您可以使 slice 调用中的范围更具体：

const character = ",";

const str = "NPA-Woodburn,OR,Woodburn,OR,97071,Bensenville,IL,60106,150.00,0.00,cash/certified funds,,enclosed,operable,,,,,";

const res = str.split(character).slice(8,9)[0]
console.log(res)
