这个简单的代码也可以工作，例如从双引号包围的字符串中删除双引号:

var str = 'remove "foo" delimiting double quotes';
console.log(str.replace(/"(.+)"/g, '$1'));

这是为懒人设计的一款简单的工具

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

如果您试图删除双引号，请尝试以下操作

  var Stringstr = "\"I am here\"";
  var mystring = String(Stringstr);
  mystring = mystring.substring(1, mystring.length - 1);
  alert(mystring);

这段代码是非常好的显示数字在文本框

$(this) =[你的文本框]

            var number = $(this).val();
            number = number.replace(/[',]+/g, '');
            number = number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');
            $(this).val(number); // "1,234,567,890"

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));
