lastIndexOf (String.lastIndexOf method)
public lastIndexOf(value:String, [startIndex:Number]) : Number
Searches the string from right to left and returns the index of the last occurrence of value
found before startIndex within the calling string. This index is zero-based, meaning that the
first character in a string is considered to be at index 0--not index 1. If value is not found, the
method returns -1.
Parameters
value:String - The string for which to search.
startIndex:Number [optional] - An integer specifying the starting point from which to
search for value.
Returns
Number - The position of the last occurrence of the specified substring or -1.
Example
The following example shows how to use lastIndexOf() to return the index of a certain
character:
var searchString:String = "Lorem ipsum dolor sit amet.";
var index:Number;
index = searchString.lastIndexOf("L");
trace(index); // output: 0
index = searchString.lastIndexOf("l");
trace(index); // output: 14
