var str= 'asd,asd,12,321,,123,6,yrtv,x,z';

A regular method, use split to split into arrays. Is it possible to use the filter method of the array? Please solve it and write it down one by one. Thank you.
Example 1:

var reg = /\d+/g;
var str = "ss12345rr3432re232";
var ms = str.match(reg)

Answer 1

str.split(",").filter(a => a !== "" && !isNaN(+a))

Answer 2

// 如果只要数字不分组的话，这个方法最简单
str.replace(/[^\d]/gi, '')
