actionscript 3 - Differences between timeline code vs Document class code -

-

i'm trying explain differences between writing timeline code vs document class code, far have:

timeline code: - doesn't require package , class declaration  document class code: - requires package , class declaration  timeline code: - starts working on top-most line  document class code: - starts working constructor function  timeline code: - loops, conditionals , event listeners can **outside** of function  document class code: - loops, conditionals , event listeners must **inside** function

are these correct, , there else trip people making transition?

time line code old , not recommended way not structured way code. still,

timeline code: - can not define access control modifier functions or variables, default, public(as far know)

document class code: - can define access control modifier

timeline code: - code runs every time control come in frame

document class code: - document class being initialized once

timeline code: - variable's lifetime while control in frame

document class code: - member variables stay alive until application ends.

edit

timeline code: - same code written in enter_frame event in document class.

document class code: - can achieve functionality of frame code using enter_frame event.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
