在ReactJS中从字符串中移除引号：指南

Question

我刚开始学习JavaScript。我有一个段落，使用str.split('.')将其分割。此外，我需要在分割后的字符串中去掉引号。如何去掉它们？

我的妈妈站起来，从地上拿起一个盒子。“我们在美国，Rune。他们在这里讲英语。你一直在说英语，就像你一直在说挪威语一样。是时候用英语了。”

我希望结果如下：

我的妈妈站起来，从地上拿起一个盒子。我们在美国，Rune。他们在这里讲英语。你一直在说英语，就像你一直在说挪威语一样。是时候用英语了。

在拆分数组之前，去除所有引号会更容易。

const paragraph = `My mamma stood up and lifted a box off the ground. “We’re in America, Rune. They speak English here. You’ve been speaking English for as long as you’ve been speaking Norwegian. It’s time to use it.”`.replace(/“|”/g,'');

console.log(paragraph);
// "My mamma stood up and lifted a box off the ground. We’re in America, Rune. They speak English here. You’ve been speaking English for as long as you’ve been speaking Norwegian. It’s time to use it."

如果您坚持先拆分数组，那么您应该在.split之后循环/映射每个句子。

const sentences = `My mamma stood up and lifted a box off the ground. “We’re in America, Rune. They speak English here. You’ve been speaking English for as long as you’ve been speaking Norwegian. It’s time to use it.”`.split('.');

const result = result = sentences.map(sentence => sentence.replace(/“|”/g,''));

console.log(result);
/*
[
   "My mamma stood up and lifted a box off the ground",
   " We’re in America, Rune",
   " They speak English here",
   " You’ve been speaking English for as long as you’ve been speaking Norwegian",
   " It’s time to use it",
   ""
];
*/

如您所见，最后一个项是空字符串。要去除它，您还可以使用.filter()。

result = sentences.map(sentence => sentence.replace(/“|”/g,'')).filter(sentence => sentence);

要去除空格，您还可以使用.trim()。

因此，将所有这些放在一起：

const sentences = `My mamma stood up and lifted a box off the ground. “We’re in America, Rune. They speak English here. You’ve been speaking English for as long as you’ve been speaking Norwegian. It’s time to use it.”`.split('.');

const result = sentences
  .map(sentence => sentence.replace(/“|”/g, '').trim())
  .filter(sentence => sentence);

console.log(result);

/*
[
  "My mamma stood up and lifted a box off the ground",
  "We’re in America, Rune",
  "They speak English here",
  "You’ve been speaking English for as long as you’ve been speaking Norwegian",
  "It’s time to use it"
]
