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

You don't use jquery for that. – xanatos Sep 11 '13 at 07:17 — xanatos, Sep 11 '13 at 07:17
What do you need this for? What's the next step? – georg Sep 11 '13 at 07:27 — georg, Sep 11 '13 at 07:27

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"]

var r = /\d+/; var str="How are you 10 doing 12 today?"; var n=str.split(r); works – Kuttan Sujith Sep 11 '13 at 07:23
@xanatos I removed the need for filter with the last version – Denys Séguret Sep 11 '13 at 07:25
@Eez It wouldn't get the three parts required by OP – Denys Séguret Sep 11 '13 at 07:30
@dystroy it will do right? last remaining part after digits will be in 3rd one. But agree that makes it more specific. – Rameez Sep 11 '13 at 07:34

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"]

+1 You're right, even if it still needs trimming. Edit : just +1 now :) – Denys Séguret Sep 11 '13 at 07:35

[just saying] if the number is first then it is adding a empty element in the array which can be avoided using `filter` function as shown in this [**link**](http://stackoverflow.com/a/2843625/1577396). – Mr_Green Sep 11 '13 at 07:53
How do I split a string with numeric and symbol like '30%'? – thednp Oct 05 '14 at 15:21
@georg no need, it surelly gonna get marked as duplicate, but I figured, it's num = str.split('%') but I am not sure if num[1] is gonna be the '%', bcz I also need that. – thednp Oct 05 '14 at 15:28

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"]

You didn't test, I guess. – Denys Séguret Sep 11 '13 at 07:18
That simply finds the integer. It doesn't split the string into an array, as he asking. – Reinstate Monica Cellio Sep 11 '13 at 07:19
@dystroy done trim i know lot of code but i was just testing my skills without regex. – Tushar Gupta - curioustushar Sep 11 '13 at 07:31
@dystroy can you please give some links from where i can learn regex.I know regex but only basics. – Tushar Gupta - curioustushar Sep 11 '13 at 07:32
