Separatorless Split 4

[MarkZK]

Hello,

How would I split/joined a string without a separator ?, for example, if I know the string will always be six random numbers long (var string = "124356" but I needed to send it through a function to return the same string with partions (splitS(string); returns "12|43|56"). which is the best way to approach this. ?

Thanks for any advice/help.

Hi

I would do it with regular expression substitution :

str.replace(/(..)\B/g,'$1|')

feherke, nice solution. Can you explain the \B, I see that it prevents the | on the end of the string but do not understand why. My solution was a 2 part process:

str.replace(/(.{2})/g, "$1|").replace(/\|$/, "")

But your code alleviates the need for the 2nd replace, I just can't figure out why.

Hi

\b matches at a word boundary
\B matches when not at a word boundary

What constitutes as a word boundary? I'm guessing start and end of string would be immediate inclusions. Empty space characters (space, tab, newline) fit in that category as well? And what about special characters (!@#$^ etc.)?

Sorry, I wasn't expecting such a quick reply, although I don't understand what's happened in either of those one liners they both worked a treat, Thanks guys.

Hi

The word boundary is the transition from [tt]\w[/tt] ( word character ) to [tt]\W[/tt] ( non-word character ).
