我正在制作一个脚本，它接收一个字符串并将其分隔在较小的字符串上。

例如：“这句话很长，我把它分成更小的部分。拉拉拉”

它将返回“This is a long sentence”、“我会将它分成更小的部分”、“Lalala”

这样做的目的是使用谷歌翻译器将文本转换为语音，但这个功能有大约 70-80 个字符的限制，所以如果字符串太大，我需要将其截断。

首先，我用点（“.”）分隔句子，然后如果句子仍然太长，我用逗号（“，”）分隔它们，如果字符串仍然太长，我将它们分隔成唯一的单词。

一切都很好，直到我尝试加入一些单词以使音频变得更加连续。由于某种原因，用逗号分隔的字符串再次连接起来。我不知道为什么。

这是代码：

试试这个，修改它以使用您的常量和参数。

var LIMIT = 20;

var res = new Array()

//strats with spliting by dot
var dotArr = "This is a long sentence. and I will separate it into smaller parts. Lalala".split(/[.]/);

for (var i = 0; i < dotArr.length; i++) {
  if (dotArr[i].length > LIMIT){

    //only when have to, split by comma
    var comArr = dotArr[i].split(/[,]/);
    for (var j = 0; j < comArr.length; j++) {
       //only when have to and that a space exists, split by space
       if (comArr[j].length > LIMIT && comArr[j].indexOf(" ") != -1 ){
         var spaceArr = comArr[j].split(/[ ]/);
         //accomulate words until we reach the limit and then push the value to res
         for (var k = 0; k < spaceArr.length;){
            var sMerge = spaceArr[k++];
            while (k < spaceArr.length && sMerge.length + spaceArr[k].length + 1 < LIMIT){
               sMerge = sMerge + " " + spaceArr[k];
               k++;
            }
            res.push(sMerge)
         }
       }else{
         res.push(comArr[j]);
       }
    }
  }else{
    res.push(dotArr[i]);
  }
}

//res contain all optimized sentences.
