ActionScript 3.0 :: Limiting Input Text To Unique Characters?
Apr 20, 2011
I already know how to limit my input text to a number of characters, but how would I go about (if possible) making sure characters do not repeat? In other words, I have a ten character input text box and I want you to be able to type pretty much any character but only one of each.
Example:
AFKEIOPCNK
What I'm trying to eliminate is this:
AANHDKDDJI
If that isn't possible, I'd like to instead detect if there are repeated characters so I can just say "that's invalid".

Is there a way to restrict the number of characters in the Flex Rich Text Editor? I guess there should be, since it's possible in a textarea. So, if I could get hold of the textarea contained in the rich text editor, I would be able to do it

Is there any way? I thought "maxChars" was promising until I learned it was only for inputting text to a textfield.The XML is coming into a dynamic text box. I need to cut it off at say 500 characters and add an ellipsis.

Since I only need numbers, can I limit dynamically embedded fonts to only numerals, periods, dashes and special characters copied from the character map?

I need the ability to create a TextArea entity in a constrained area (i.e., it is located at x and y and is w pixels wide and h pixels high and have that never change.), containing a proportional width font. As such, no 'num char entry limit' strategy is feasible. They need to be able to fill the entire area, and if that means 1,000 period '.' characters, or 200 '#' or "W' characters, then so be it.
The two lines following this one consist of 30 periods followed by 30 Ws.

I cannot limit a user to 30 characters. They need to be limited by using a TextArea that will let itself be filled until full, and then refuse further input until space is created by removing existing content. I then need to print that TextArea _as rendered on the user's screen_. Any 'scrolled' lines would be unprintable, and therefore the user's entry must be limited BEFORE any scrolling occurs, or contrariwise, when scrolling occurs, the last entered content would need to be removed and the entity forced to un-scroll. I can program this. It won't be elegant, and in fact will be quite stupid, as any programming where a change event is called with each keystroke or paste and then conditions tested is inefficient, wasteful, and well.

I basically need to store a string of characters from an input text box and have them displayed at the last frame of the quiz. I declared the variable holding the input text as _global.player in the first frame, and upon clicking the start button the code is:
on (release) { _global.player=player.text; gotoAndStop (2); }
These variables are not referenced again until the last frame of the quiz, which reads thus:
stop();playerdisplay.text=_global.player;score.text=_global.correct;'Endng Comments Generator'if (_global.correct<=3) { phrase="Try a little harder next time";}if (_global.correct>3 + _global.correct<7) { }comment.text=phrase;
Yes, I know the global.correct coments are not yet complete, but i dont think that should be causing any issue with the playerdisplay.text (the dynamic text box to display the player name). If anyone could give me a hand that would be great. Nothing appears in the dynamic text box when the final frame of the movie loads.

I have an input text field with embedded fonts together with embedded special characters.

I'm confused - becase I have embedded fonts etc - and all should work but for some reason it does't...

I have a text input box on a site i'm currently building. Problem is, when testing it, some letters don't register as being pressed (and no, its not my keyboard before you ask hehe).
The letters which don't show up are, "B,C,E,F,G,H,I,J,K,L,M,N,Q,T,U,V,X,Y,Z". In fact, the only letters that are recognized and displayed when I type into it are: "A,D,O,P,R,S,W".

I have taken over an old project of a registration page after a short quiz and for some reason it is not possible to enter special characters in the text input field. example: @ but it is also not possible to enter a y or a capital W and some others. I have not found any thread or google infos on this problem and am short of reprogramming the whole thing in as3 which is very tedious because the whole site is still running as2 and we do not have time nor money to update.

I've created a ComboBox skin by extending mx.skins.ProgrammaticSkin. It's working fine, except I can't figure out how to limit the width of the text. Is there a way to control this within the skin?
See the attached image for an example of the text going too far. I would like it to stop before the separator line to the left of the down arrow.

I have a textfield that acts as a log in that it routinely gets messages added to it. I want to limit the number of lines the textfield can display - that is, if the textfield exceeds a certain amount of lines, the oldest lines that were added are removed and the rest of the lines of text are shifted up. Basically I'm wondering if there is a cleaner way to do this, as my technique seems inefficient:
Code:
const MAX_LOG_LINES:int = 50;
// assuming parameter message is a string that ends in to add a line break.
function addText(message:String):void

I have a form for signing up for a email newsletter, requesting name, phone number, email, etc. However, for some reason, it won't allow me to enter "3" "4" or the "@" symbol in any of the textfields. You can see how that could be a problem.I'm working with a preexisting site, build by someone else. The SWF on the site doesn't have this problem, (it works fine) but when I create a new SWF from the FLA they got from the previous designer, I have these problems, even before I made any changes.
The site was built with something newer than Flash 8 (I couldn't open it with Flash 8), but older than CS5 (when I save a new version of the FLA, it tells me it will no longer be compatible with older versions of Flash) Could this be caused by that?
the code from the form:
Code:
stop ();
this.tabEnabled;
name.tabIndex = 1;
street.tabIndex = 2;

I have an issue with font scaling of a dynamic text box.
Currently i have one input box named input_1 with a variable attached to it named "choc_1".
Also, i have a dynamic text box named dynamic_1 with variable "choc_1".
When the user types something on the input box then the dynamic box changes instantly and displays what the user has written.
auto scale-size the fonts to a smaller size if the user types many letters.
The input_1 box has a 13 character limit. My initial font size is 200, i want to scale down so when the user types 10 letters they fit the box and they don't go out of screen. I want to use one line, so wrap or multiline is not possible.
here's a code that i'm trying to fix but i can't get the dynamic box to change:

I have a input text field, where people can type text in, limited to a maximum set of characters. And, instead of just putting a text under this textfield saying 'max. 50 characters', I want to have a countdown that counts down (wow, some descriptions really do speak for themselves) from 50 (the maximum of input characters) to 0, in accordance of the characters in the textfield.

Whenever I have my Textfield focused and enter a character, the input field enters an additional duplicate character, meaning I have to backspace one character for every character I enter.If it was a Keydown problem the same should happen when i backspace a character as well.

So I have an input text and let's say the user inputs "Hello" in it.Then I want to calculate the total value of what is entered in a fashion like H=4, e=2, l=3, o=6. Meaning the total value of the entered characters would be 18 in this case.

I have an input textfield nested inside a movieclip, i embedded a set of characters but when i run the movie i can still input characters that were not part of the embedding list. The input text field has both an instance name and variable name. If i copy that text field into an empty fla file, it works correctly by not allowing character inputs that were not embedded.

the last of many problems, is that at the very end of the test, you're shown your score, and you have the option to type your name in a text box and click "save". Doing so will apply you score data (time elapsed, date, correct answers and percentage) along with the name you typed in, and output in a form, that you can save or print off, or whatever. The problem is, the input text box will not let you type in it. If you mouse over it, the mouse stays a pointer, you don't get the text tool. If you click on it, the cursor appears for a split second after you release the mouse button, but you cannot type anything in it.This is the actionscript for the output form:
Code:
//
function saveRecord(record:String, field:String, now:Object, score:Object):Void {
