| 6.18.1.String.lastIndexOf() |

Syntax |
string.lastIndexOf(string, num)
string.lastIndexOf(string)
|
|
The lastIndexOf() method returns the indexed start position of the string passed, starting from the right and going left. |
You can specify an index, defined by num in the syntax definition, to start your search for the string specified. |
This method is the same as the String.indexOf() method, but it starts at the end of the string. |
