New function split()

I was testing something here and found that the AS command Split() is not available in 3dfa This is a VERY usefull command as it lets you send an array from the server as a comma delimited string and turn it back into an array in flash.
So being me I just wrote my own function to do the same thing.

Example call
code:
string1="one,two,three,four,five,six,seven,hi there"

myarray=root.split(string1,",")

trace("array length="+myarray.length)

for (x=0;x<myarray.length;x++){

 trace(myarray[x])

}
where string1 is the string with the data in it. You can use any delimiter but comma is commonly used.

Heres the function
code:
function split(BL_string,delimiter){

BL_array=new Array()

/*	Function to replace missing split functionality

  	call it myArray=root.split(string,delimiter)

*/

//Get first element in array

   first=BL_string.indexOf(delimiter,0);

	end=BL_string.indexOf(delimiter,first+1);

		BL_array[0]=BL_string.substr(0,first);

		

//Now get the rest of the elements

 start=first

 idx=1

	while(start<>-1){

	end=BL_string.indexOf(delimiter,start+1);

	if (end==-1){

		BL_array[idx]=BL_string.slice(start+1,BL_string.length);

	}else{

	 	BL_array[idx]=BL_string.substr(start+1,(end-start-1));

	}

		idx++

		start=BL_string.indexOf(delimiter,start+1);

		

		}

return BL_array



}//end if split function
