Adding space between numbers

Question

I\'m trying to make a number input. I\'ve made so my textbox only accepts numbers via this code:

function isNumber(evt) {
    evt = (evt) ? evt : window.even         


        

Answer 1

Easiest way:

1

var num = 1234567890,
result = num.toLocaleString() ;// result will equal to "1 234 567 890"

2

var num = 1234567.890,
result = num.toLocaleString() + num.toString().slice(num.toString().indexOf('.')) // will equal to 1 234 567.890

3

var num = 1234567.890123,
result = Number(num.toFixed(0)).toLocaleString() + '.' + Number(num.toString().slice(num.toString().indexOf('.')+1)).toLocaleString()
//will equal to 1 234 567.890 123

4

If you want ',' instead of ' ':

var num = 1234567.890123,
result = Number(num.toFixed(0)).toLocaleString().split(/\s/).join(',') + '.' + Number(num.toString().slice(num.toString().indexOf('.')+1)).toLocaleString()
//will equal to 1,234,567.890 123

If not working, set the parameter like: "toLocaleString('ru-RU')" parameter "en-EN", will split number by the ',' instead of ' '
