Javascript 正则表达式 - 如何获取大括号之间的文本

发布于 2024-09-12 11:58:06 字数 647 浏览 3 评论 0原文

我需要获取大括号之间的文本（如果有）。我确实找到了另一篇文章，但从技术上讲，它没有正确回答：用于提取方形或卷曲之间文本的正则表达式括号

它实际上并没有说明如何实际提取文本。现在我已经了解了：

var cleanStr = "Some random {stuff} here";
var checkSep = "\{.*?\}"; 
if (cleanStr.search(checkSep)==-1) { //if match failed
  alert("nothing found between brackets");
} else {
  alert("something found between brackets");
}

如何从字符串中提取“东西”？另外，如果我更进一步，我如何从这个字符串中提取“东西”和“句子”：

var cleanStr2 = "Some random {stuff} in this {sentence}";

干杯！

原文

I need to get the text (if any) between curly brackets. I did find this other post but technically it wasn't answered correctly:
Regular expression to extract text between either square or curly brackets

It didn't actually say how to actually extract the text. So I have got this far:

var cleanStr = "Some random {stuff} here";
var checkSep = "\{.*?\}"; 
if (cleanStr.search(checkSep)==-1) { //if match failed
  alert("nothing found between brackets");
} else {
  alert("something found between brackets");
}

How do I then extract 'stuff' from the string? And also if I take this further, how do I extract 'stuff' and 'sentence' from this string:

var cleanStr2 = "Some random {stuff} in this {sentence}";

Cheers!

要提取大括号之间的所有匹配项，您可以执行以下操作：

function getWordsBetweenCurlies(str) {
  var results = [], re = /{([^}]+)}/g, text;

  while(text = re.exec(str)) {
    results.push(text[1]);
  }
  return results;
}

getWordsBetweenCurlies("Some random {stuff} in this {sentence}");
// returns ["stuff", "sentence"]

To extract all occurrences between curly braces, you can make something like this:

function getWordsBetweenCurlies(str) {
  var results = [], re = /{([^}]+)}/g, text;

  while(text = re.exec(str)) {
    results.push(text[1]);
  }
  return results;
}

getWordsBetweenCurlies("Some random {stuff} in this {sentence}");
// returns ["stuff", "sentence"]
