Hi I wondered if anyone could help. As my deadline is looming to a dangerous
point and im stuck:|
I have a dynamic text field in flash that is populated by an input box.
The dynamic text field has a maxmium width it can be. So i have it as
multiline WITH wodrwap on.
My problem is that I have to send this data to server and for the php to be
able to text the text and output the text as it is displayed in flash.
There seems to be no way of finding the linebreaks and passing them in the
string as far as I can see? Does anyone have any ideas on this or a workaround?
The noose is tightening.
thx in advance

Hi again
The problem is that I have tried to detect line breaks in the text field and I
just cant seem to get to them:|
I have tried (trace(testField.text.indexOf('\n'))) aswell as newline etc and
it always returns a -1.
As mentioned in original post. The textfield is a fixed width with wordwrap
set to true. I read somewhere that wordwrap somehow makes the linebreaks
undetectable? I am hoping this isn't the case. All i need to be able to is send
the contents of the textfield to a php page with the linebreaks included. Any
help on this would be great. This is as2 targetting flashlite 2.1.
thx in advance |

I have tried and no dice. To try and be clear I have a text field on stage say
160 pixels wide. I type copy in say a thirty h's. Say fifteen fit on first line
and rest push onto second. I need to be able to send to server the linebreak
flash has placed in there. /n first exist I'm there and /r only exists at the
very end of the text. It's driving me nuts |

oh. you'll need to create a custom function to do that.
duplicate your textfield and its properties (which can all be automated using
actionscript) except enable the duplicate's autoSize property, don't assign
text/htmlText, yet and assign its _height to be small like 10.
then start assigning text one character at a time until your textfield's
bottomScroll property increments. at that point is a line break. |

Hi again
Firstly kglad, many thanks for your help, it is very much appreciated.
I have implemented your suggestion and it is pretty much there. However, there
seems to be a slight lag in the processing which results in the pseudo line
break characters being added a few characters late. Taking font embedding off
the fields has improved this, but it it is still out enough that it will screw
up my text rendeing when its passed to the server.
My code is as below:
origStr = orig.text
origStrLength = origStr.length;
currentScroll = 1
newText.autoSize = true;
newText.wordWrap = true;
temp_str = "";
for (var i=0; i < origStrLength; i++ ){
temp_str += origStr.charAt(i)
newText.text = temp_str;
amount = newText.bottomScroll;
if(amount > currentScroll){
temp_str += "*"
currentScroll ++;
trace("insertLineBreak" + currentScroll)
}
}
The textfields have the same properties, namely multiline is set and thats it.
As mentioend I have removed font embedding, but would ideally need this atleast
for the original text box. I can work around that but the slippage in
positioning of the linebreak is a real problem still. And more worrying if it
is down to horsepower is this will be running on mobiles.
any further help would be fantastic |

nope, sorry kglad Im still not there:(
I cannto sem to get it right the linebreak text i place in is either 1 char or
out. Code is below:
origStr = orig.text
origStrLength = origStr.length;
currentScroll = 1
newText.autoSize = true;
newText.wordWrap = true;
//temp_str = "";
for (var i=0; i < origStrLength; i++ ){
if(amount > currentScroll){
newText.text += "*"
currentScroll = amount;
newText.text += origStr.charAt(i)
} else {
newText.text += origStr.charAt(i)
//newText.text = temp_str;
amount = newText.bottomScroll;
}
amount = newText.bottomScroll;
}
I know this must be something really stupid, but i just cant see it:~ |

| why are you adding a "*" to your textfield after the line break? |
