How to Search and replace a string in a string array

[Chinmayee1]

Hi,

I have a string such as

var str = "Hello Servicenow user Chinmayee Mishra.User user ID is : 1234s" ;

I have to find the ID and replace with another ID , lets say

var newStr = "Hello Servicenow user Chinmayee Mishra.Your user ID is : 987c";

The string  length is not constant as the names can be different.

How do I do it ? Please help.

Thanks & Regards,

Chinmayee Mishra

You can use regex to extract the user id like the below screenshot then you can use .replace method to change the ID.

Regex -:(.*)

Hi Chinmayee,

you can use this:

var newStr = str.replace(str.split(" ").splice(-1), "987c");

Thank you but the string length is not constant. the ID might not be at the end always. there might be other sentences too. The only similar string would be "user ID is :" . 

Can you help please ?

ID will always remain at last right, even though string changes?
