How to dynamically dot-walk in script?

[Gage]

I am trying to script a dynamic dot-walk. To simplify I have included the array of fields that includes a dot-walk in the script below.

var arrExample = ['first_name', 'last_name', 'location.city'];
var grUser = new GlideRecord('sys_user');
grUser.get('e663cd73db3fc7002fdfdd3b5e961970');

for (var i = 0; i < arrExample.length; i++){
    
    // Tried this, did not work
    //gs.log(grUser[arrExample[i]]);

    // Current workaround
    eval('gs.log(grUser.' + arrExample[i] + ');');

}

Current Background Script Output:

*** Script: John
*** Script: Smith
*** Script: Atlanta

I want to get this output without using the eval() statement if possible. Any help would be appreciated!

Why did you put it in an array if there is only one record you are looking at?

Try something like:

Both of these return the same value.

You could check to see if the "field" value has a "." in it. If it does then you parse it into 2 fields and use the [][] approach, otherwise you just use the [] approach. I hope this helps.

getElement([dotwalk field]) appears to work. I am able to get the desired result without using an eval statement using the script below:

var arrExample = ['first_name', 'last_name', 'location.city'];
var grUser = new GlideRecord('sys_user');
grUser.get('e663cd73db3fc7002fdfdd3b5e961970');

for (var i = 0; i < arrExample.length; i++){

    gs.log(grUser.getElement(arrExample[i]));

}
