restricting carriage returns in text input fields??

[kirov]

Does anyone know if it's possible to restrict hard returns in text input fields? I've tried something like this:
my_txt.restrict="^\u0013", and a bunch of variations thereof, but nothing seems to keep the Enter key from doing it's thing.

Second best would be to traverse through a string a user has entered and replace hard returns with a space or dash, but again I've had no luck looking for \n or \r. I've tried entering text and hard returns into a dynamic textfield set to input, but when I try this:
var n:Number = my_txt.indexOf("\n")...
trace("n: "+n) //traces "n: -1"

Anyone have any insight into this?

What do you mean?
Do you just want them to write on one line?

There are properties you can change within the Flash Workspace.

No, I want the text field to wrap. But I need to disable hard returns because I'm sending the text up to the server, where it gets converted to XML and is stored in a database. Unfortunately, any text that has hard returns gets truncated after the return.

Example: I send this text to the server "Here is some text [hard return] I'm sending to the server."

When I later request that text from the server I get "Here is some text"

So I need to either strip hard returns from the text before I send it, or better yet, disable carriage returns altogether.

Aah, okay. I see what you mean.

I've been trying to restrict the carriage return key for the last hour or so...no luck =_=

So I guess you'll have to resort to using a function to listen for when the carriage return is pressed, and stripping it.

Note: Carriage return is either decimal "13" or Hexidecimal "\u000D", although I have a sneaking suspicion that a function to strip the paragraph of carriage returns is gonna need something else...

Oh well, best of luck.

NOTE: I'll try to write a "CR stripping function", and if it works I'll post it here. Otherwise it's up to you ^_^

inputfield.addEventListener(Event.CHANGE, onChange);

private function onChange(e:Event):void {
if ( inputfield.text.charCodeAt(inputfield.text.length - 1) == 13 ) {
inputfield.text = inputfield.text.substr(0, inputfield.text.length - 1);
}
}
