jamert, this is a complete SW post but I figured I'd post it as an alternative to the above solution since it's what I always use.

The substring method requires 2 parameters. The position of the first character in the string to pull, and the position of the last character in the string to pull. However, at a glance I've always found the substring method to be confusing. In marouanemeft's example above, it will return the first 2 characters in the string variable d. However, if you look at the parameters passed (0 and 1), there is only a difference of 1. Again, at a glance I find this confusing because I would expect it to only return 1 character (because of the difference between the two parameters).

Thankfully ECMA has provided us with an alternative. The substr method accepts 2 parameters as well - the position of the first character in the string, and the length of the substring you wish to pull. So, to modify marouanemeft's example to use the substr method:

d.[!]substr([/!]0, 2[!])[/!]

At a glance this is more intuitive. You know immediately how long the substring will be that is returned.
