changes() function is not working while giving it with a variable name

[sruthi22]

Hi All,

We have a requirement where we need to see if a field value is changed in business rule (using .changes()). But we cant give the field name directly, instead should get field name from a property. And this is giving us 'undefined'. Please find below a similar code snippet 

var gr = new GlideRecord('sn_customerservice_case');

if(gr.get(sys_id))

{

var field = 'number';

gs.info(gr.field)

}

And this gives undefined as a response. Is there a way to achieve this?

Thanks in advance,

Sruthi.

Hi @sruthi22 you can try this code

var field_names = ['number', 'short_description']

field_names.forEach(function(field_name){
gs.info(current[field_name]t.getLabel()+" changes? "+current[field_name].changes())
})

or this

var field_names = ['number', 'short_description']

field_names.forEach(function(field_name){
var element = current.getElement(field_name)
gs.info(element.getLabel()+" changes? "+element.changes())
})

Either of these methods should log the value of the number field on the returned record, assuming sys_id is supplied/defined:

var gr = new GlideRecord('sn_customerservice_case');
if (gr.get(sys_id)) {
    var field = 'number';
    gs.info(gr.getValue(field));
}

var gr = new GlideRecord('sn_customerservice_case');
if (gr.get(sys_id)) {
    var field = 'number';
    gs.info(gr[field]);
}

var gr = new GlideRecord('sn_customerservice_case');
if (gr.get(sys_id)) {
    var field = 'number';
    gs.info(gr.getElement(field));
}
