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。
.split
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()。
.filter()
result = sentences.map(sentence => sentence.replace(/“|”/g,'')).filter(sentence => sentence);
要去除空格，您还可以使用.trim()。
.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" ] */
