String operation in javascript

Question

How can I get only 'ABCD' from string 'ABCD150117T15' in java script.

I would like strip rest of the string from 'ABCD' in this example and generally everything until but excluding the first number character.

thanks

Don't understand what exactly you wanted to do...you could achieve it by using .substring function on string. — Pankaj Parkar

Go ahead and add that to your question. "Match text before numbers start" — John Starich

You can match for a-z

'ABCD150117T15'.match(/^[a-z]+/i)

you can match anything that is not a number

'ABCD150117T15'.match(/^[^\d]+/)

Use regex then to match the first digit, and then subtring it to the text;

var str = 'ABCD150117T15';
var index = str.search(/\d/);
var text = str.substr(0,index);

Wouldn't it just be index and not index+1? (I'm not familiar with str.search)

EDITED : My bad, I totally forgot string.seach return an 0_started index like substr

'ABCD150117T15'.match(/^\D+/)[0]

This would give you everything until the first number then :)

I doubt the string is always ABCD, but who knows

Actually I may get sometimes ABCD150117T15/A150117T15. It's not a hard coded value. I am looking for word/letter before number starts in the string
