如果字符串为0，则从字符串中删除第一个字符

Question

I know it is related to Remove first character from a string if it is a comma but in this case that solution doesn't work for me. Maybe its because now I'm dealing with a number. Simply I want javascript to remove 0 from 08 but don't touch 10 ; only remove 0 when it is the first character.

This solution doesn't work: replace(/^0/, "")

Answer 1

You can try this:

alert("08".replace(/^0+/, ''));

And if you are dealing with numbers then you can use parseInt() function.

Answer 2

Easy way with regex :

^0+(?!$)

and feel free to use String replaceFirst function.
