lastIndexOf Method

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

Syntax

strVariable.lastIndexOf(substring, startindex)

"String Literal".lastIndexOf(substring, startindex)

Arguments

strVariable

The name of a String object.

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 negative, startindex is treated as zero. If it is larger than the greatest character position index, it is treated as the largest possible index.
Searching is performed right to left. Otherwise, this method is identical to the indexOf method.
