index Property (JScript 5.6)


RegExp.index

The object associated with this property is always the global RegExp object.

The index property is zero-based. The initial value of the index property is ΓÇô1. Its value changes whenever a successful match is made.

The following example illustrates the use of the index property. This function iterates a search string and prints out the index and lastIndex values for each word in the string.
