For some reason I can't seem to match a parentheses in Flex using Regex to save my life. What's wrong with this?
var commandTxt:String = "switchview(adf)";
var switchViewArray:Array = commandTxt.match(new RegExp("switchview(", "i"));
I've tried dozens of things, but I can't seem to get a match the parentheses. What's the catch here?
I need to match a string that begins and ends with the same character in flex...I know the long hand way (RE being - "a[^(a")]a" | "b[^(b")b" | etc...), but I'm positive this isn't what I'm required to do (midterm tomorrow!);
I need to do this in flex, but if you can think of a short regex for it, I may be able to convert it to flex notation.
What I was thinking of was something along the lines of -
%%
int firstChar;
%x string;
%%
[Code].....
But this bugs me in a few ways, first, having that variable makes this not a regular language; second, I don't know if you can even use a variable to in a pattern match; and third, I don't know how NOT to match it, if it's just a normal string. And third, I don't know how to return everything that's been matched while in 'string'
I want to do something like this:"3*4".replace(/([0-9]+)[*]([0-9]+)/g, String(Number("$1") * Number("$2")))And no, i don't want to do that, but something more complex.
View 2 RepliesI'm having a problem with using regexp to validate form fields, everything is working fine as long as I don't explicitly try to match a dot(.) character. This fails on both email and the voorletters regex. I've tested both these regexes in RegExr and they are doing what they're supposed to there.
Code:
var regex_voorletters:RegExp = /^([A-Z.])+$/i;
var regex_email:RegExp= /^([w-.]+)@((?:[w]+.)+)([a-zA-Z]{2,4})$/i

I am confused with how component life cycle goes when component build in MXML. and if MXML calls methods automatically then how to call any method in life cycle explicitly.
View 1 RepliesIn UI component life cycle, I heard validation and invalidation events. Please explain me about these events in short. What does updateDisplayList() method do in that life cycle. Please explain me in short if possible.
View 2 RepliesDriven on by curiosity, I'm trying to understand the Life Cycle used by Flex Application. I've done a little research on this argument; the two key concepts used into the FlashPlayer are:
SWF Frame: it's the logical unit that contains graphical code and as code Flash Player Frame: it's the time interval used by Flash runtime to update the screen and defined by frameRate property
If so, could you explain me the relationship bewteen these two concepts? In particular, are they paired togheter or not? The main rule is: the Flash Player streams in a swf; until a full SWF Frame is read, the Flash Player cannot render it.
I'll try to explain what I need to understand. For the sake of simplicity, suppose you have a two frame application: SWF FR 1 and SWF FR 2.
In general (for example in CS4) a frame is considered as a logical unit (delimited by ShowFrame tag) where you can attach as3 code. This as a simplified version of a swf file, i think:
Header // frameRate is defined here
Symbols, classes etc... // this is FR1
=== ShowFrame ===
Symbols, classes etc... // this is FR2
If you have two frame, FR1 and FR2, Flash starts executing FR1 and goes to the next one (FR2). If you don't stop the excution, the Player executes and renderes code contained into FR1 and FR2 through an infinite loop. On the contrary, when you stop the execution, for example in FR2, the flash player loops executing code contained in FR2.

I get an error telling me to put a Right parentheses somewhere??
Scene=Scene 1, layer=Layer 1, frame=1, Line 69')' expected
I know that my dot syntax grammar is really bad but WHERE on earth does the right parentheses go in the code?
Code:
if (minion.x, minion.y hitTestPoint(range.x, range.y, true))
nvm I got it to work after I realized I was using hitTestPoint wrong
should have been minion.hitTestPoint instead
took me like 20 minutes to get why my code is not functionning... this line: tempRef.x=(limitL-dist-tempRef.width/2)+(tempRef.width+dist)*(i+1); after auto format becomes like this: tempRef.x=limitL-dist-tempRef.width/2+tempRef.width+dist*i+1; that's not the same thing at all...may I know why this is happening?

I have some xml, I want to give it to a List dataprovider, but based on an attribute match.
My Xml

And I am trying to do something like below, If I remove (@name=="general") from below line it gives me all property

But it gives me error, so basically I want to get all property based on rows attribute name matching general

View 2 RepliesI had this same issue when I created an application using google's javascript API and the solution was to have closure on the callback function creating the multiple markers.I can not seem to find an example for making multiple custom markers, with anything other than using some random math function to create the multiple markers.
GlobalVars is a class that contains static public var types to keep up with however many addressess, lats, lngs, etc...I have tried using markermanager but it has some issues that I finally just gave up on. Starting with
retrieveLatLngAddress.addEventListener(GeocodingEvent.GEOCODING_SUCCESS, function(event:GeocodingEvent):void{
This is where I begin geocoding by address, rather than using an httpservice, as I was doing before, but I ran into issues of one httpservice result would return faster than another, which would in turn place the wrong data with the wrong marker.
Obviously, I have not found a solution, because this way is doing the same thing.Question being, how can I retrieve multiple markers info and keep all the markeroptions in order with the information being returned.
Here's the code:
public function makeMultipleMarkers(destinationAllObj:Object):void {
removeRouteMarkers();
myMarkers = [];
GlobalVars.myIcon = [];

I've written a url validator for a project I am working on. For my requirements it works great, except when the last part for the url goes longer than 22 characters it breaks. My expression:/((https?)://)([^s.]+.)+([^s.]+)(:d+/S+)/i
It expects input that looks like "http(s)://hostname:port/location". When I give it the input: https://demo10:443/111112222233333444445
it works, but if I pass the input https://demo10:443/1111122222333334444455
it breaks. You can test it out easily at[URL].. Oddly, I can't reproduce the problem with just the relevant (I would think) part /(:d+/S+)/i. I can have as many characters after the required / and it works great. Any ideas or known bugs?

i want to check in Adobe AIR if given regex is valid. I'm looking for somtehing similar like here: How to check if a given Regex is valid?
I dont want to compare regex and text-value - i jus want to check if this regex is valid. If someone type invalid regex - for example: "x{5,-3}" or "(((^^$$$)//)" or something like this i just need to communicate to him that this regular expression is not valid - its not proper regular expression.
In Java it can be done by:

find the suitable regular expression to validate a string that has comma separated numbers, for e.g. '1,2,3' or '111,234234,-09', etc. Anything else should be considered invalid. for e.g. '121as23' or '123-123' is invalid.
