从正则表达式中提取数字

Question

var myString = 'Sent from your Zoom trial account - Your verification code is: 621226';
var regEx = /(\d+)$/g;
var result = regEx.exec(myString);

然而结果= [621226,621226]而不仅仅是[621226]

Answer 1

将.match()与regEx一起用作myString链接的参数。

var myString = 'Sent from your Zoom trial account - Your verification code is: 621226';
var regEx = /(\d+)$/g;
var result = myString.match(regEx);
console.log(result);
