indexOf Method
Description
Finds the beginning of a substring within a string object.Syntax
intIndex = strVariable.indexOf( substring, startindex )
intIndex = "String Literal".indexOf( substring, startindex )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 beginning of the string.Return Value
An integer value indicating the beginning of the substring within the string object. If the substring is not found, a -1 is returned.
Remarks
If startindex is out of bounds (either negative or larger than the greatest character position index), startindex will be treated as zero if negative, and as the largest possible index if too large.
Searching is performed left to right. Otherwise, this function is identical to lastIndexOf. Only the first occurrence of the substring is found.
