根据字符串中的标点将字符串拆分为数组元素-JavaScript [英] Split String Into Array Elements Based On Punctuation In String - JavaScript

问题描述

我想按句子将字符串拆分成单独的数组元素 .因此，每个周期后都需要进行拆分.

即这个:

 爱是燃烧的东西，它会发出火热的戒指.受狂野欲望的束缚，我陷入了火圈. 

会变成这样:

  ['爱是燃烧的东西，它制造了火热的戒指.'，被狂野的欲望所束缚，我掉进了火圈"，] 

在这种情况下，

Array [0] 将是爱是燃烧的东西，它会发出火热的戒指." .

我尝试过:

  function splitLyrics(string){让newArray = [];for(让i = 0; i< string.length; i ++){let character = string [i];让句子=";if(字符！==."){句子.concat(字符);}newArray.push(sentence);}返回newArray;}console.log(splitLyrics(爱是燃烧的东西，它制造了火热的戒指.由于野心勃勃的欲望，我陷入了火环.")); 

正如您所看到的，我的问题是我不知道如何将各个字符元素组合成句子元素，并在句号之间将其分隔开.

按照我现有的逻辑，有哪些功能可以实现我正在寻找的功能?

解决方案

您可以使用正则表达式和 .match 代替 - 匹配一个非空格字符，然后是非句点字符，然后是按句点字符:

  const splitLyrics = str =>str.match(/\ S [^.] * \ ./g);console.log(splitLyrics(爱是燃烧的东西，它发出火热的戒指.由于野心勃勃的欲望，我跌入了火环."));  

这也很容易扩展到其他以句子结尾的标点符号，例如感叹号和问号:

  const splitLyrics = str =>str.match(/\ S [^.?！] * [.?！]/g);console.log(splitLyrics(爱是燃烧的东西，它发出火热的戒指.被狂野的欲望所束缚，我跌入了火环./pre>

如果需要 var song = sing(); ，并且测试人员继续调用 song ，那么您应该编写一个返回函数，尽管这似乎很奇怪:

  const sing =()=>str =>str.match(/\ S [^.] * \ ./g);const song = sing();console.log(song(爱是燃烧的东西，它发出火热的戒指.被狂野的欲望所束缚，我跌入了火环."));  

看来kata希望您粘贴整首歌的歌词，然后返回相应的行:

您可以在此处找到完整的歌词.

那么要么这样做:

或者，对于这个非常重复的 歌曲"，您可以自己创建歌词，虽然可能不是很清楚，但这可能是练习的重点:

  const sing =()=>[... Array.from({长度:98}，(_，i)=>[`$ {99-i}瓶啤酒在墙上，$ {99-i}瓶啤酒.把一瓶下来，传给我，$ {99-i-1}瓶啤酒在墙上.]).平坦的()，`1瓶啤酒在墙上，1瓶啤酒.`下来一并传递，墙上再也没有啤酒瓶了.`，`墙上不再有啤酒瓶，啤酒也没有瓶.`去商店，在墙上购买更多的99瓶啤酒.];const song = sing();console.log(song [0] ==='墙上有99瓶啤酒，有99瓶啤酒.');  

I want to split a string into separate array elements by sentence. So a split needs to occur after every period.

I.e. this:

Love is a burning thing and it makes a fiery ring.
Bound by wild desire, I fell in to a ring of fire.

Will become this:

[ 'Love is a burning thing and it makes a fiery ring.',
 'Bound by wild desire, I fell into a ring of fire', ]

Array[0] in this case will be "Love is a burning thing and it makes a fiery ring.".

I tried this:

function splitLyrics(string) {
  let newArray = [];

  for (let i = 0; i < string.length; i++) {
    let character = string[i];
    let sentence = "";

    if (character !== ".") {
      sentence.concat(character);
    }

    newArray.push(sentence);

  }

  return newArray;

}

console.log(splitLyrics("Love is a burning thing and it makes a fiery ring. Bound by wild desire, I fell in to a ring of fire."));

And as you can see, my problem is that I don't know how to combine the individual character elements into sentence elements, separated by when there's a period.

What functions are out there that could achieve what I'm looking for, following my existing logic?

https://www.codewars.com/kata/99-bottles-of-beer-1/train/javascript

解决方案

You might use a regular expression and .match instead - match a non-space character, followed by non-period characters, followed by a period character:

const splitLyrics = str => str.match(/\S[^.]*\./g);

console.log(splitLyrics("Love is a burning thing and it makes a fiery ring. Bound by wild desire, I fell in to a ring of fire."));

This is easily extendible to other sentence-terminating punctuation too, like exclamation and question marks:

const splitLyrics = str => str.match(/\S[^.?!]*[.?!]/g);

console.log(splitLyrics("Love is a burning thing and it makes a fiery ring. Bound by wild desire, I fell in to a ring of fire. Foo bar! Bar baz? Buzz."));

If var song = sing(); is required, and the tester proceeds to call song, then you should write a function that returns a function, though this seems like a very odd thing to do:

const sing = () => str => str.match(/\S[^.]*\./g);
const song = sing();
console.log(song("Love is a burning thing and it makes a fiery ring. Bound by wild desire, I fell in to a ring of fire."));

It appears that the kata is expecting you to paste in the entire lyrics for the song and then return the appropriate line:

You can find the complete lyrics here.

So either do that:

Or, for this particular "song", which is very repetitive, you can create the lyrics yourself, which might have been the point of the exercise, though it's not very clear:

const sing = () => [
  ...Array.from(
    { length: 98 },
    (_, i) => [
      `${99 - i} bottles of beer on the wall, ${99 - i} bottles of beer.`,
      `Take one down and pass it around, ${99 - i - 1} bottles of beer on the wall.`
    ]
  ).flat(),
  `1 bottle of beer on the wall, 1 bottle of beer.`,
  `Take one down and pass it around, no more bottles of beer on the wall.`,
  `No more bottles of beer on the wall, no more bottles of beer.`,
  `Go to the store and buy some more, 99 bottles of beer on the wall.`
];
const song = sing();
console.log(song[0] === '99 bottles of beer on the wall, 99 bottles of beer.');
