last occurrence of a string in a string in flex

Question

Is there any inbuild function to find out the last occurrence of a string pattern in a string in action script .

Answer 1

Yes, check out the lastIndexOf method of the String object.

PS. If by string pattern you mean a regular expression rather than a literal string, you could use the match method instead, passing a RegExp and setting the g (global) flag; then you could check the last match in the returned result.
