JavaScript regex to extract text and number

Question

I am still new on regex (I should learn), I just need JS regex to extract string and number from a text like this: [number][string].

( /^(\d+).(\s+)/?)

Any help please?

Can you show some text you need to extract from?

I think you are looking for '/\d+[a-z]+/gi' :

var x = "123123K, 333D".match(/\d+[a-z]+/gi); 
console.log(x);    //["123123K", "333D"]

UPDATE: x is array. You can iterate over it and extract number and text:

xitem.match(/\d+/)[0]      //number
xitem.match(/[a-z]+/i)[0]  //text

P.S.: About \s:

Matches a whitespace character, which in ASCII are tab, line feed, form feed, carriage return, and space; in Unicode, also matches no-break spaces, next line, and the variable-width spaces (amongst others).

sorry Engineer, I was not clear : for example if I have 123123D I want to extract 123123, and D

That updated part with two regexes will also match strings like "D123" and "1D1D1"... Makes more sense to capture the two interesting parts: console.log("123123K".match(/(\d+)([a-z]+)/gi));.

your solution dcoder seems to be the union of the two regexp of enginer. thanks to all.

@DCoder After /\d+[a-z]+/gi regexp matching "D123" and "1D1D1" can't be in matched pieces.All pieces are of "{number}{text}" kind.

If the square brackets are in the line as well then do the following:

/^\[(\d+)\]\[(\s+)\]$/

If they are not

/^(\d+)(\s+)$/

I am trying this but x results null:var x = "123123M".match(/^(\d+)(\s+)$/); console.log(x);

\s is used to match whitespace. "123123M" doesn't have whitespace.
