Question

所以我试图在这个维基百科页面上删除所有括号及其内容。我尝试使用.replace(/(.*)/g, '')。结果是一个空字符串。所以我尝试不使用g部分。然后我失去了文本开头的很大一部分。我也尝试用一个单词替换括号，例如Red，结果是：

RedRed RedRed RedRed RedRed RedRed RedRed

我想知道你们中是否有人知道这里发生了什么以及你们是否有解决方案。

以下是文字：

您必须通过匹配不包含任何其他括号的括号对从内到外删除括号，然后重复该过程，直到不再有对为止：

function deParenthesise(text) {
  var replaced = text;
  var before = replaced;
  do {
    before = replaced;
    replaced = replaced.replace(/\([^()]*\)/g, '');
  } while (replaced != before);

  return replaced;
}

Answer 2

使用正则表达式可能会很棘手，因为你可以有多个级别的括号，......就像你在开始时那样。

一个简单的纯Javascript解决方案虽然不是很难做到。

const txt = `Norway ( ( listen); Norwegian: Norge (Bokmål) or Noreg (Nynorsk); Northern >Sami: Norga), officially the Kingdom of Norway, is a sovereign state and >unitary monarchy whose territory comprises the western portion of the Scandinavian Peninsula plus the remote island of Jan Mayen and the archipelago of Svalbard. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land. Until 1814, the kingdom included the Faroe Islands, Greenland, and > Iceland. It also included Bohuslän until 1658, Jämtland and Härjedalen until > 1645, Shetland and Orkney until 1468, and the Hebrides and Isle of Man until > 1266. Norway has a total area of 385,252 square kilometres (148,747 sq mi) and a population of 5,258,317 (as of January 2017).`;

function removeBrackets(txt) {
  const letters = Array.from(txt);
  const output = [];
  let bcount = 0;
  let pos = 0;
  while (pos < letters.length) {
    const letter = letters[pos];
    if (letter === "(") bcount +=1;    
    if (!bcount) output.push(letter);
    if (letter === ")") bcount -=1;
    pos += 1;
  }
  return output.join("");  
}

console.log(removeBrackets(txt));

Answer 3

这个从字符串中删除所有“（.....）”。

/([^\(\)]*?)(\s*\([^\(\)]*?\))([^\(\)]*?)/$1$3/g

（[^（）] *？）：没有标记'（'和'）'的文字作为第一组（$ 1）
（适用\ S *（[^（）] *）？）：
可以以Space（或类似的东西）开头的文本（\ s），
那么一个'（' 比没有'（'和'）'和
的文字然后a'）'作为第二组（$ 2）

（[^（）] *？）：没有标记'（'和'）'作为第三组（$ 3）的文字

[^（）] ：除'（'和'）'之外的所有标志

[^（）] *？：零以上的标志除了'（'和'）'

删除两个括号之间的字符串Javascript
