Need help with JavaScript String substr().

Annie10 · ‎05-25-2023

Hello,

I have a string contains "abc\1234"

I would like to extract from the back slash and get the number only such as "1234"

Can someone please help? Thank you

@Annie10 Please continue to use double back slashes, generally \ has a special meaning example: \n is for the next line and hence scripting languages doesn't allow you to type one single backslash and to cut the meaning of backslash you have to use double slashes.

Conclusion is \\ is equivalent of \ in a string.

Please use the same line of code and it should work fine.

return source.u_name.slice(source.u_name.indexOf('\\')+1);

Thanks!!

Try this one

var string = "abc\1234";
var newString  =string.replace('abc\','') 
gs.info(newString);

Log: 
*** Script: 1234

Please mark helpful if correct, thanks!

Hi Zack,

I'm trying to test the script in background script, but getting the following error:

Arun_S1 · ‎05-25-2023

Hello @Annie10,

Please try the below script.

In the script orig_string (original string) contains \\ as an escape sequence (additional / for the ServiceNow to understand that next / has no special meaning).

IndexOf function is used to identify the position of \ in the string and slice method is used to retrieve the text that is available after /.

var orig_string = "abc\\1234";
var position= orig_string.indexOf("\\")+1;
var ext_string = orig_string.slice(position);
gs.info(ext_string);

Hi @Arun_S1

My original string contains double black slash "abc\12345"

I was trying to get the number after the back slash using transform map script like this, but it did not work:

return source.u_name.toString().replace(/(\d+)/g, "");
