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);

However result = [621226, 621226] instead of just [621226]

Answer 1

Use .match() with regEx as parameter chained to myString .

 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);
