Script help - How to get the value for variable field from the 'current' record

harinalamalapu · ‎03-09-2016

How to get the value of a field on a current record using the 'current' keyword if the field name is a variable? Ex: current.u_description returns the description of the current record, say from a Change Request. but what if 'u_description' is a variable?

var result = current.u_description / This produced the result as "Sample Change Request"

Versus

var fieldName = u_description;

var value = current.fieldName //tried this approach #1 - This produced the result as 'undefined'

var value = current+'.'+fieldName //tried this approach #2 - This produced the result as '[object GlideRecord].u_description'

I will have to use the above piece of code from a business rule on change request, so current refers to the current change record.

var value = current.fieldName //tried this approach #1 - This produced the result as 'undefined'

The system is searching for the column with the name fieldName, so it is not preferred to use parameter for the variable. If you want to use parameter its better to use getValue function.

var fieldName = 'u_description';

var value = current.getValue(fieldName); //this will work

Mark if it is helpful or correct

Try current.variables.field_name

Hi Mike,

In my example, did you mean trying like 'current.variables.fieldName' (the variable in my example is fieldName) ? I just tried that, but no luck. It returns 'undefined'.

Hi,

have you tried g_form.getValue('field_name/variable name'); ?

Please try if it works

Thanks,

Tadz

Hi Tedz,

I believe g_form is used only in client side scripts, but I am looking for a server side script like Business Rule.

Thanks,
