Client Script: DisplayValue of a field

[palmen]

I'm having issues to get the display values of two fields in a client script.

g_form.getDisplayValue('field_name') will return the number of the incident and not the actual display value of the field.

The fields I need the display values for is State (state) and Configuration Item (cmdb_ci).

From what I read in other threads you should use

g_form.getDisplayBox('field_name').value;

When I try this I get an error instead on the form when the Client Script is triggered

The code I'm using in the onChange client script is the following

var state = g_form.getDisplayBox('state').value;
alert(state);

The alert won't show, only the above error is displayed.

Any ideas what I could do to get the Display Value of the state field?

Hey Fredrik,

I tested this on my instances, Helsinki Patch 2 & Geneva Patch6-Hotfix2, and I'm not seeing the error you are referring to. I believe what you are trying is working correctly.

1. g_form.getDisplayBox('field_name').value;  

The error is most likely caused by a different field. Look at state, as this isn't a reference field.

Do you mind sharing your client script?

For the choice list, I believe you're going to make a call to the server on this one to get the display value. Sad, when the display value is RIGHT THERE.

Thanks for the info, there were actually no error with the reference field (cmdb_ci). it's the value from the state field causing trouble

This is the script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
   return;
   }
   //Build up text
   var text = '';
   var num = g_form.getValue('number');
   var title = g_form.getValue('short_description');
   var state = g_form.getValue('state');
   var impacted = g_form.getDisplayBox('cmdb_ci').value;
   var start = g_form.getValue('work_start');

   if (newValue == 'true') {
   text = num + '\n' + impacted + ' - ' + title + '\nStart Time: ' + start + '\nFor more information, and update kindly check your email';
   g_form.setValue('u_text', text);
   }
}

So the only thing not working is to get the display value from the state field which obviously is a choice field and nothing else.

Hi Brett,

This issue is caused when the field name provided in the function not present on the form. Either 'state' or cmdb_ci not available on the form. Right click on the field labels and verify backend names of the fields.

The field names are correct. I can put the same client script on state and it does the same error. g_form.getDisplayBox('fieldname').value works best for reference fields. It does not like choice fields.
