Question

昨晚，我的小弟弟问我是否有可能制作一个程序，将每个字母替换为字母表中的另一个字母，将其转换为代码，并将其恢复到正常状态。

所以我做了这个：http://www.skyetheguy.com/novatranslationtool

从各方面来说，它完成了这项工作，但我觉得，在代码方面，它是笨拙的，因为所有的离开，我真的很想提高我对循环之类的知识...

编辑：上面已经更新了DodgerThud的惊人答案并且像梦一样工作。 :)梦想成真！

此外，这是非常的天空，但让这个与长于两个字符的东西一起使用真是太棒了。我的代码肯定不会这样做。但是，你知道，所有那些有撇号的有趣代码......好东西！

要告诉你为什么我做了我所做的所有令人难以置信的任意和循环的事情......

如果你做了其他人在这里谈到的其他正常替换事物（至少从我发现的事情），你最终会在某一点上替换你自己的工作。例如，如果你想让B成为A，但是你希望A成为C，那么如果你输入＆＃34; BA＆＃34;，你就会回来＆＃34; CC＆＃34;而不是＆＃34; AC＆＃34;。因此，我的代码实际上会将每个角色一次一个地吐出来。
我做了那些乏味的事情＆＃34; .toUpperCase（）＆＃34;确保此工具区分大小写的东西 - 因此，如果我输入小写或大写的键，它将始终生成适当的位置。这就是RegExp为我工作的原因。
它还考虑了换行符和字母表中未包含的随机符号等内容。

我知道确实有更简单，更节能的方法来编码，但我根本不知道如何。

Answer 1

我将扩展我的评论并向您展示如何简化您的代码并删除大量代码。

首先，您不需要使用数组。 String个对象本质上已经是字节值的数组。因此，您可以执行此操作而不是创建大型数组

var alphabet:String = "abcdefghijklmnopqrstuvwxyz";
var substitution:String = "mnbvcxzlkjhgfdsapoiuytrewq";

要访问特定字符，您只需在字符串上调用indexOf方法即可。

var indexOfJ = alphabet.indexOf("j");
trace(indexOfJ); //puts out 9

您现在已经知道如何从特定索引中获取字符串的字符。

var charAtIndex7:String = alphabet.charAt(7);
trace(charAtIndex7); //puts out "h"

在此编辑fom：

当我昨晚写下答案时，看起来我只是半醒。 double for循环的问题只是它总是会一直运行，即使它找到了一个被接受的if子句。你已经想通了你自己的最后一个else子句导致输入字符被打印25次。所以，让我们解决它。

function cipher(input:Textfield, output:Textfield, alphabet:String, substitution:String){
    textinProgress = input.text;
    var result:String = "";

    for(var b=0;b<textinProgress.length;b++)
    {
        var anyHit = false;
        for(var i=0;i<alphabet.length;i++){
            if(textinProgress.charAt(b).search(alphabet.charAt(i)) == 0){
                result += substituton.charAt(i);
                anyHit = true;
                break;
            }
            else if(textinProgress.charAt(b).search(alphabet.charAt(i).toUpperCase()) == 0){
                result += substituton.charAt(i).toUpperCase();
                anyHit = true;
                break;
            }
            else if(textinProgress.charAt(b) == "\r"){
                result += "\n";
                anyHit = true;
                break;
            }
        }
        if(anyHit == false){
            result += textinProgress.charAt(b);
        }
    }
    output.text = result;
}

我今天早些时候有一位同事为我测试了这段代码，它应该按预期工作。

但是，我们无法简化您的代码。我们可以通过用小写和大写字母定义字母和替换变量来删除第二个if子句。

var alphabet:String = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
var substitution:String = "mnbvcxzlkjhgfdsapoiuytrewqMNBVCXZLKJHGFDSAPOIUYTREWQ";

您还应该能够在字母和替换字符串中添加特殊符号，例如\r。

var alphabet:String = "\rabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
var substitution:String = "\nmnbvcxzlkjhgfdsapoiuytrewqMNBVCXZLKJHGFDSAPOIUYTREWQ";

我不完全确定这是否有效，但它应该。

现在您已经大大缩短了代码，但我们甚至可以进一步缩短代码。内部for循环真的是必要的吗？因为我们的字母和我们的替换长度相同，所以我们可以更加简化这一点。

function cipher(input:Textfield, output:Textfield, alphabet:String, substitution:String){
    textinProgress = input.text;
    var result:String = "";

    for(var b=0;b<textinProgress.length;b++)
    {
        var index:int = alphabet.indexOf(textinProgress.charAt(b));
        if(index >= 0){
            result += substitution.charAt(index);
        }else{
            result += textinProgress.charAt(b);
        }
    }
    output.text = result;
}

全部放在一起。

var alphabet:String = "\rabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
var substitution:String = "\nmnbvcxzlkjhgfdsapoiuytrewqMNBVCXZLKJHGFDSAPOIUYTREWQ";

function cipher(input:Textfield, output:Textfield, alphabet:String, substitution:String){
    textinProgress = input.text;
    var result:String = "";

    for(var b=0;b<textinProgress.length;b++)
    {
        var index:int = alphabet.indexOf(textinProgress.charAt(b));
        if(index >= 0){
            result += substitution.charAt(index);
        }else{
            result += textinProgress.charAt(b);
        }
    }
    output.text = result;
}

function encode_btnclick(event:MouseEvent):void{
   cipher(inputText, outputText, alphabet, substitution);
}

function decode_btnclick(event:MouseEvent):void{
   cipher(inputText, outputText, substitution, alphabet);
}

function recode_btnclick(event:MouseEvent):void{
   cipher(outputText, outputText, alphabet, substitution);
}

这应该能够处理

任意长度的文字
换行符
大写和小写字母
未定义的字符

您应该搜索Substitution ciphers，例如，最简单的一个是Caesar cipher。
