Description

Finds the last occurrence of a substring within a String object.

Syntax

strVariable.lastIndexOf( substring, startindex )
"String Literal".lastIndexOf( substring, startindex )

The lastIndexOf method syntax has these arguments:

substring	The substring to search for within the string object.
startindex	An optional integer value specifying the index to begin searching within the string object. If omitted, searching begins at the end of the string.

Remarks

The lastIndexOf method returns an integer value indicating the beginning of the substring within the string object. If the substring is not found, a -1 is returned.

If startindex is out of bounds (either negative or larger than the greatest character position index), startindex is treated as zero if negative, and as the largest possible index if too large.

Searching is performed right to left. Otherwise, this method is identical to indexOf.
