如果只想从开头或结尾删除引号，请使用以下正则表达式:

'"Hello"'.replace(/(^"|"$)/g, '');

使用replaceAll

const someStr = 'He said "Hello, my name is Foo"';

console.log(someStr.replaceAll('"', '')); 

// => 'He said Hello, my name is Foo'

如果你只想删除边界引号:

function stripquotes(a) {
    if (a.charAt(0) === '"' && a.charAt(a.length-1) === '"') {
        return a.substr(1, a.length-2);
    }
    return a;
}

如果字符串看起来不像“带引号的文本”，这种方法不会触及字符串。

这是为懒人设计的一款简单的工具

var str = '"a string"';
str = str.replace(/^"|"$/g, '');

如果只想从开头或结尾删除引号，请使用以下正则表达式:

'"Hello"'.replace(/(^"|"$)/g, '');

这工作…

var string1 = "'foo'"; var string2 = '"bar"'; function removeFirstAndLastQuotes(str){ var firstChar = str.charAt(0); var lastChar = str[str.length -1]; //double quotes if(firstChar && lastChar === String.fromCharCode(34)){ str = str.slice(1, -1); } //single quotes if(firstChar && lastChar === String.fromCharCode(39)){ str = str.slice(1, -1); } return str; } console.log(removeFirstAndLastQuotes(string1)); console.log(removeFirstAndLastQuotes(string2));
