I have a regular expression that works in JavaScript and does not work
in ActionScript 3, even though both languages supposedly use the
ECMAScript standard for regular expressions. I need the expression to
return true when ever it tests the two strings below:
true,$
true, $
I need the expression to return false whenever the string is not the
same as one of the two above.
I've attached the HTML that demonstrates that the regular expressions
work in JavaScript. Can you modify the same expressions in the Flex
code, provided below, to produce the same result?
Thanks.
