如何在 .txt 文件中查找/定位最常用的单词并更改它

Question

我正在尝试找出如何在文本文件中找到一个最常用的词并更改该单个词以使其包含在其他东西中，例如：freewordchoice（免费+常用词+选择）和无处不在该单词是该单词可以更改的文本的文本。我一直在为这样的事情发疯，但我找不到它。我对 Javascript 非常陌生，这正是我想要使用的。要上传和显示文本工作正常，我不明白的是我如何定位最常用的单词并在它实际显示在浏览器上之前在整个文本中更改它。在我看来，我需要某种变量来找到单词并在某个地方存储世界，以及一个变量，我可以在其中放入要添加或更改目标单词的内容。

示例文本：阿拉丁和神灯的古腾堡计划 Etext

信息/问题更新：下面的代码在上面的示例文本的全文中查找最常用的词。我现在这个词是阿拉丁。问题是我可以让它正确地替换 Aladdin 这个词。我确实打印出 fooAladdinbar，就像我想要的那样，但不是仅仅更改 Aladding = fooAladdinbar，而是在示例文本中的每个字母之间添加 fooAladdinbar。

这已解决，是一个可变问题。

Answer 1

这并不完美，但可以，这是一个演示：

（这个Demo只是找常用词）

• 它使用正则表达式分割文本
• 然后数单词
• 然后返回最常用的词

var data = document.getElementById("data").value;

var allWords = data.split(/\b/);
var wordCountList = {};

allWords.forEach(function(word){
  if(word !== " "){
    if(!wordCountList.hasOwnProperty(word)){
      wordCountList[word] = {word: word, count:0};
    }
    wordCountList[word].count++;
  }
})


var maxCountWord = {count:0};
for(var propName in wordCountList){
  var currentWord = wordCountList[propName];
  if(maxCountWord.count<currentWord.count){
    maxCountWord = currentWord;
  }
}
console.info(maxCountWord);

textarea{
  width:100%;
  height:100px;
}

<textarea id="data" >
<!-- start slipsum code -->

The path of the righteous man is beset on all sides by the iniquities of the selfish and the tyranny of evil men. Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy My brothers. And you will know My name is the Lord when I lay My vengeance upon thee.

<!-- end slipsum code -->  
</textarea>

<div id="result"></div>

替换这个词你也可以用正则表达式：
（这个Demo只是替换了一个常用词）

function freewordchoice (free, word, choice){
  var data = document.getElementById("data").innerHTML;   
  var replaceExpression = new RegExp("\\b"+word+"\\b","gi");
  console.info(replaceExpression);
  data =data.replace(replaceExpression, free + word + choice);
  document.getElementById("result").innerHTML = data;   
   
 }


freewordchoice("<b>", "the", "</b>");

<b>Before:</b>
<div id="data" >
<!-- start slipsum code -->

The path of the righteous man is beset on all sides by the iniquities of the selfish and the tyranny of evil men. Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy My brothers. And you will know My name is the Lord when I lay My vengeance upon thee.

问题出在这一行

common = 'the,a,do,in,with,this,so,that,of,and,not,did,when,what,were,went,was,as,  
if,who,had,at,can,you,which,while,will,to,till,then,them,their,she,  
he,once,out,no,must,many,me,is,it,his,him,her,about,have,i,has,your,  
would,where,whom,s,on,from,for,by,but,all,said,my,';

问题出在字符串末尾,said,my,'; 删除最后一个逗号，它应该可以工作，如下所示：

common = 'the,a,do,in,with,this,so,that,of,and,not,did,when,what,were,went,was,as,  
if,who,had,at,can,you,which,while,will,to,till,then,them,their,she,  
he,once,out,no,must,many,me,is,it,his,him,her,about,have,i,has,your,  
would,where,whom,s,on,from,for,by,but,all,said,my';

由于通过最后一个逗号，最后一个单词是一个空字符串。
