In alert box i got comma seperated friend ids so i use split function post on each users wall seperately i dont know whats wrong here please help me

Answer 1

Most probably friendID is already an array. If you call alert the array is converted to a string and becomes a comma separated list of values.

Note that converting an array to a string is not the same as calling JSON.stringify (where you get also brackets and double quotes around elements when they're strings)

Answer 2

The JavaScript split() function is for the type string ie for eg.

var friendid='1,34,67';

As VisioN says, when you alert an array you get comma separated values.
