使用正则表达式在JavaScript中的花括号之间获取内容 [英] Getting content between curly braces in JavaScript with regex

问题描述

我正在尝试使用JavaScript在花括号之间获取内容.我找到了这个线程:正则表达式以在花括号之间添加字符串"{我想要花括号之间的字符串}"

I am trying to get content between curly braces with JavaScript. I found this thread: Regex to get string between curly braces "{I want what's between the curly braces}"

但是我不知道如何应用正则表达式，例如/\ {([^}] +)\}/

But I do not know how to apply a regex like /\{([^}]+)\}/

我已经尝试过 string.replace('/\ {([^}] +)\}/'，''); ，但这是行不通的.

I have tried string.replace('/\{([^}]+)\}/','');, however this does not work.

推荐答案

以下是使用示例:

var found = [],          // an array to collect the strings that are found
    rxp = /{([^}]+)}/g,
    str = "a {string} with {curly} braces",
    curMatch;

while( curMatch = rxp.exec( str ) ) {
    found.push( curMatch[1] );
}

console.log( found );    // ["string", "curly"]
