Javascript 中字符串中的数字数组

Question

I am trying to get an array of numbers from a string that does not have a token to use as a split.

Example:

var myString = 'someString5oneMoreString6';

Expected result:

var result = [5, 6];

How to archive this with javascript before ES2015?

Answer 1

You could match all digits and convert the result to numbers.

 var string = 'someString5oneMoreString6', array = string.match(/\d+/g); for (var i = 0; i < array.length; i++) array[i] = +array[i]; console.log(array);

Answer 2

you can split by regex and map to process.

 var str = 'someString5oneMoreString6'; const array = str.split(/[a-zA-Z]+/).filter(x => x).map(x => Number(x)); console.log(array);
