This is a convenient Javascript function that returns a value from a string of delimited values based upon the position index specified.

Example Usage:

getToken("steve@hotmail.com", 2, "@") //returns "hotmail.com"
getToken("123-45-6789", 2, "-") //returns "45"
getToken("first,middle,last", 3, ",") //returns "last"

Code:

function getToken(sVal, iIndex, sDelimiter)
{

	if (sDelimiter.length > 0)
	{
		var aSubString = new Array();
		aSubString = sVal.split(sDelimiter);

	
		if (iIndex > aSubString.length
			|| iIndex < 1)
		{
			return "";
		}
		else
		{
			return aSubString[iIndex - 1]
		}

	}
	else
	{
		return "";
	}

}
