Split a string by integer in it using jquery

Question

I have long string like

"When I was 10 year old"

I have to get this string split to an array: ["When I was", "10" , "year old"].

The integer can be different in different cases and the sentence may also change.

In short i want to split a string by integer in it Is it possible?

How can i use regex in conjugation with split in Jquery/java-script

Answer 1

You can use

var str = "When I was 10 year old";
var arr = str.match(/(\D*)\s(\d*)\s(\D*)/).slice(1);

Result :

["When I was", "10", "year old"]

Answer 2

The regexp you're looking for is as simple as

/\D+|\d+/g

Example:

> str = "When I was 10 year old"
"When I was 10 year old"
> str.match(/\D+|\d+/g)
["When I was ", "10", " year old"]

To get rid of spaces:

> str.split(/(?:\s*(\d+)\s*)/g)
["When I was", "10", "year old"]

Answer 3

you can use this

DEMO

var r = /\d+/;
var str = "When I was 10 year old";
var x = $.trim(str.match(r).toString());
var str_split = str.split(x);
var arr = [];
$.each(str_split, function (i, val) {
    arr.push($.trim(val));
    arr.push(x.toString());
});
arr.pop();
console.log(arr); // ["When I was", "10", "year old"]
