Array.index (Property)

A special property provided only when the array results from a string match.

Availability:

JavaScript - 1.2
JScript - 5.5
Internet Explorer - 5.5
Netscape - 4.0
Property/method value type:Number primitive
JavaScript syntax:-myArray.index

When the String.match() method is used, it returns an array as a result. If the match used a pattern that made only a single match (i.e. the g attribute was not used) then the array returned will have this additional index property.

The index property will contain the character location within the original string where the match occurred.
