I am trying to search JavaScript split alpha-numeric string functionality but I am not able to find it.

I want to have functionality like Split function in JQuery

Example:

"NewFolder333".AplhaNumericSplit();
["NewFolder","333"]///Result Splitted Array

Thank You

• Can you add all possible input strings – Tushar Commented Dec 17, 2015 at 6:22
• Changed To split("NewFolder333"); – Ali Jamal Commented Dec 17, 2015 at 6:24
• i dont think there is any direct methods in jquery or javscript for your purpose, i would suggest you to create simple manual parser for this – dreamweiver Commented Dec 17, 2015 at 6:24

Do matching instead of splitting..

string.match(/[a-z]+|\d+/ig)

tl;dr

<string>.match(/[^\d]+|\d+/g)

---

To split an Alpha Numeric String in order to obtain ["NewFolder" ,"333"] from "NewFolder333" or ["section", "4", "rubrique", "2"] from "section-4-rubrique-2" you can use a Regex as pattern of match().

• String.prototype.match.

The RegExp pattern will be interested you is

/[^\d]+|\d+/g

• // : Create a regex.
• g : Allow your match function to obtain all matched part.
• [^\d]+ : Obtain a string that contain possibly all char except numeric.
• ´| : OR.
• \d+ : Obtain all numeric char.

So in following code, result will contain ["NewFolder" ,"333"]

var result = "NewFolder333".match(/[^\d]+|\d+/g);
alert(result);

---

With a little modification, you will also be able to ignore , _ or -

• [^-_ \d]+ : Obtain a string that contain possibly all char except numeric, , _ or -.

And following result will contain ["section", "4", "rubrique", "2"]

var result = "section-4-rubrique-2".match(/[^-_ \d]+|\d+/g);
alert(result);

or

var result = "section_4-rubrique_2".match(/[^-_ \d]+|\d+/g);
alert(result);

or

var result = "section-4 rubrique-2".match(/[^-_ \d]+|\d+/g);
alert(result);
