如何用非数字的任何东西分割字符串

Question

string input:

"12 apples, 3 oranges, 10 grapes"

solution:

let arr= inputString.split(" ");

issue to solve:

how would I go about splitting with anything that isn't a number?

string examples:

• no spaces

  • 12apples,3oranges,10grapes

• numbers that are inside ()

  • there are some (12) digits 5566 in this 770 string 239 (i want only 12, 5566, 770, 239)

• string of numbers having math done on them

  • 33+22 (should be split into 33 and 22)

what i thought could work:

arr= inputString.split("isNaN");

Answer 1

You could use a regular expression:

 const str = '12apples,3oranges,10grapes'; const splitString = str.match(/(?:\d+\.)?\d+/g); console.log(splitString);

Answer 2

let str = "12apples,3oranges,10grapes"

console.log(str.split(/[^\d]/g).filter(e => e))

str = "there are some (12) digits 5566 in this 770 string 239"

console.log(str.split(/[^\d]/g). filter(e => e))

str="33+22"

console.log(str.split(/[^\d]/g). filter(e => e))

Answer 3

let str = "12 apples, 3 oranges, 10 grapes" let arr = str.match(/\d+(.\d+)?/g) console.log(arr)
