Actionscript 3使用正则表达式替换字符串中的单词

我正在开发一个涉及创建Adobe Flash应用程序的项目，该应用程序可以更改输入文本框中文本的时态。最初的例子是： “亚特兰蒂斯的城市迷路了，狼人应该受到指责，我很伤心，我的朋友也很难过，居民和亚特兰蒂斯人也不高兴，这真是太浪费了。Actionscript 3使用正则表达式替换字符串中的单词

我已经想出了如何使它过去式和现在式。但我似乎无法弄清楚如何将“我是”的部分从过去时改回现在时（我是）。请帮忙。

original_btn.addEventListener(MouseEvent.CLICK, ConvertOriginal); 
    past_btn.addEventListener(MouseEvent.CLICK, ConvertPast); 
    present_btn.addEventListener(MouseEvent.CLICK, ConvertPresent); 

    function ConvertOriginal(e:MouseEvent):void { 
     body_txt.text = "The city of Atlantis is lost. The werewolves were to blame. I am saddened and so were my friends. The residents and Atlantis are unhappy too. It is such a waste."; 
} 
    function ConvertPast(e:MouseEvent):void { 
     var myPattern1:RegExp = /\s(is|am)\s/g; 
     var str:String = body_txt.text; 
     body_txt.text = body_txt.text.replace(myPattern1, " was "); 
     var myPattern2:RegExp = /\sare\s/g; 
     body_txt.text = body_txt.text.replace(myPattern2, " were "); 
} 
    function ConvertPresent(e:MouseEvent):void { 
     var myPattern1:RegExp = /\swas\s/g; 
     var str:String = body_txt.text; 
     body_txt.text = body_txt.text.replace(myPattern1, " is "); 
     var myPattern2:RegExp = /was/g; 
     body_txt.text = body_txt.text.replace(myPattern2, " I am "); 
     var myPattern3:RegExp = /\swere\s/g; 
     body_txt.text = body_txt.text.replace(myPattern3, " are "); 
}

使用单词边界'\ B'，而不是'\ s'和更换部件，你不不需要添加空格。 –

谢谢Avinash Raj。但是，如何改变“我是”回到“我是”。因为\ bwas \ b被替换为“is” – Alisa

，所以我一直得到“我是”，对不起，我在语法部分非常虚弱。 –

你需要使用正则表达式替换的顺序是：与is

\bwere\b

\bI was\b与I am
\bwas\b与are

这里是你的modifie d功能：

function ConvertPresent(e:MouseEvent):void { 
    var myPattern1:RegExp = /\bI was\b/g; 
    var str:String = body_txt.text; 
    body_txt.text = body_txt.text.replace(myPattern1, "I am"); 
    var myPattern2:RegExp = /\bwas\b/g; 
    body_txt.text = body_txt.text.replace(myPattern2, "is"); 
    var myPattern3:RegExp = /\bwere\b/g; 
    body_txt.text = body_txt.text.replace(myPattern3, "are"); 
}

您可以使用字符串替换方法，将它，像这样

private function replaceAll(pattern:*,replacementStr:String,originalString:String):String { 
     if (originalString!= null) { 
      while (originalString.search(pattern) != -1) { 
       originalString= originalString.replace(pattern,replacementStr); 
      } 
     } 
     return originalString; 
    }
