You can use RegExp.
您可以使用正则表达式。
var rex:RegExp = /[\s\r\n]+/gim;
var str:String = "This is a string.";
str = str.replace(rex,'');
// str is now "Thisisastring."
For trimming front and back of strings, use
要修剪字符串的正面和背面，请使用
var rex:RegExp /^\s*|\s*$/gim;

If you have access to the AS3 Flex libraries, there's StringUtil.trim(" my string ")too. See herefor the docs.
如果您可以访问 AS3 Flex 库，也可以访问StringUtil.trim(" my string ")。有关文档，请参见此处。
It doesn't do exactly what the OP was after, but as this was the top answer on google for AS3 String trimming, I thought it'd be worth posting this solution for the more usual Stringy trimmy requirement.
它并不完全符合 OP 的要求，但由于这是谷歌对 AS3 字符串修剪的最佳答案，我认为值得发布此解决方案以满足更常见的字符串修剪要求。

Tested and works on AnimateCC for iOS air app:
在 AnimateCC for iOS air 应用程序上测试并运行：
// Regular expressions
var spaces:RegExp = / /gi; // match "spaces" in a string
var dashes:RegExp = /-/gi; // match "dashes" in a string
// Sample string with spaces and dashes
loginMC.userName.text = loginMC.userName.text.replace(spaces, ""); // find and replace "spaces"
loginMC.userName.text = loginMC.userName.text.replace(dashes, ":"); // find and replace "dashes"
trace(loginMC.userName.text);

The simplest way of removing not only spaces but any char for that matter, is as follows,
不仅删除空格而且删除任何字符的最简单方法如下，
//Tested on Flash CS5 and AIR 2.0
//Regular expressions
var spaces:RegExp = / /gi; // match "spaces" in a string
var dashes:RegExp = /-/gi; // match "dashes" in a string
//Sample string with spaces and dashes
var str:String = "Bu s ~ Tim e - 2-50-00";
str = str.replace(spaces, ""); // find and replace "spaces"
str = str.replace(dashes, ":"); // find and replace "dashes"
trace(str); // output: Bus~Time:2:50:00
