javascript - 如何将带有序数后缀的数字转换为javascript中的数字

Question

string = Number(string)

我希望它返回 13，而不是我得到 NaN，请问我该如何处理

Answer 1

尝试使用parseInt()

If parseInt encounters a character that is not a numeral in the specified radix, it ignores it and all succeeding characters and returns the integer value parsed up to that point. parseInt truncates numbers to integer values. Leading and trailing spaces are allowed.

let string = "13th";

string = parseInt(string);
console.log(string);
