Split a string in jquery

Question

How to split these strings in jquery?

• Mode1
• 2Level

I want to get only the numbers from the above two strings in jquery... The strings may be Mode11,Mode111,22Level,222Level etc the characters Mode and Level wont change...

Answer 1

Try this:

var num = parseInt(myString.match(/\d+/)[0]);

Answer 2

You could do something like this:

var numbers = "Mode111".match(/\d/g).join("")
var alpha = "Mode111".match(/[a-z]/gi).join("")

I think there is an easier way with match collections but I can't find anything to show whether javascript supports them. I will see if I can find it.

Answer 3

You probably want the String.prototype.match method:

var str = 'Mode1';
var match = str.match(/\d+/);
var number = match && +match[0];
// If `str` contained no numbers then number === null

The unary plus operator (+) casts its operand to an actual number (from a string containing numbers).

Answer 4

var str = 'Mode123';
var num = str.match(/\d/g).join('');

or

var num = str.replace(/\D/g,'');

Answer 5

I think it would help you

var number = input_string.replace(/\D/g,'');

Answer 6

var myString="Mode111"; var num =myString.replace(/[a-zA-Z]/g,"");
