Differences between substr and substring In Flex

The difference can be seen from the literal meaning:

• String. substr (START: Number = 0 Len: Number = int. max_value): String
• String. substring (START: Number = 0, end: Number = int. max_value): String

 

Substr parameters:

• Start intercepts the specified index
• Number of Len interceptions (including start indexes)

 

Substring parameters:

• Start intercepts the specified index
• End until the index is completed.

 

The simple meaning is that substr "specifies the number of interceptions ". Substring "where to intercept .."
