08.10Actionscript 3 TextField renders excessive line breaks
Hi all,
I was working on a project for musicnation.com, their EPK. I had to render text in a textfield that was coming from an XML feed, text that is entered by users. It can be filled with different types of line feeds, notable the:
\n = linux
\r = mac (prior to macos being based on freebsd I guess)
\r\n = the damned pc linefeed.
The TextField object in Flash seems to render both \r and \n as linefeeds. Therefore I was getting way too many linefeeds in my rendered text.
Here is my solution:
Actionscript:
-
var pcLB:RegExp = /\r\n/g;
-
var macLB:RegExp = /\r/g;
-
var linuxLB:RegExp = /\n/g;
-
-
_text = _text.replace(pcLB, "\n");
-
_text = _text.replace(macLB, "\n");
Tada! _text is of type String. The /g is VERY important at the end of the declaration of the RegExp, it means it will replace ALL instances. If you do not put /g it wont.
