* JacksonDunstan.com 的 http://jacksondunstan.com/articles/2461 | |
* 介绍了在as3中创建"Multi-Line Strings"的方式,在后继评论中叙述了 | |
* 可以使用xml的CDATA标签方便创建多行字符。 | |
* | |
* 使用xml的CDATA标签创建多行字符最初应该是由 http://ticore.blogspot.com 提出 | |
* 但是创建的多行字符使用trace输出会发现格式有问题(空行的行数) | |
* 可以使用正则表达式修正 | |

AS3 has never had very good support for multi-line strings… until now. | |
Today’s article discusses the proper and improper ways of writing multi-line strings | |
and delves into the bytecode so you really understand what’s going on. | |
please read JacksonDunstan.com's blog (http://jacksondunstan.com/articles/2461) | |

str = str.replace(/^\s*[\r\n]/, ""); //剔除起始换行符 | |
str = str.replace(/[\r\n]\s*$/, ""); //剔除末尾换行符 | |
//str = str.replace(/[\r\n]{2,}/g, "\r\n"); | |
str = str.replace(/[\r\n]+/g, "\n"); //剔除多余空行 | |
str = str.replace(/^\s+/gm, ""); //剔除起始位置字符, 设置multiline修饰符用于多行替换 | |
str = str.replace(/\s+$/gm, ""); //剔除结束位置字符, 设置multiline修饰符用于多行替换 | |
trace(str); //将会输出标准的期望格式 |
