Javascript正则表达式 - 如何在大括号之间获取文本 [英] Javascript regex - how to get text between curly brackets

问题描述

我需要在大括号之间获取文本（如果有的话）。我确实找到了这个其他帖子，但从技术上讲，它没有正确回答：
正则表达式，用于在方括号或大括号之间提取文本

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

它实际上并未说明如何实际提取文本。所以我有这么远：

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");
}

如何从字符串中提取东西？如果我进一步说明，如何从这个字符串中提取'stuff'和'sentence'：

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}";

干杯！

推荐答案

要提取花括号之间的所有匹配项，你可以这样做：

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"]
