lastIndexOf()

Syntax:

lastIndexOf( substring, index )

Return:

The character position in the string at which the substring was found. If the substring is not found the return value is -1.

Parameters:

substring – the substring to search for in the string. Substring can be a string or a variable name containing a string. Substring should be surrounded by quotes if it is a string. This parameter is required.

index – the index position to start searching from. Index can be a number or a variable containing a number. Index is a zero-based index. This parameter is optional and will start at the end of the string if not entered.

Remarks:

This function will search for the substring starting at the end of the string (or the index position you specifed) and work towards the beginning of the string.
