Help with simple onChange script to populate one field, based on another

[Zhivko]

Hi, I am trying to setup a dependency between 2 string fields on one of our forms (change_request table if that matters)

I tried a few things based on what i found here in the community, but unsuccessfully.

This is the most basic thing I could come up with and even that did not work.

I am setting the field name that this is supposed to apply to to Category.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue == '') {
return;
}

if (g_form.getValue('category') == 'Systems')
g_form.setValue('u_responsible', 'Jack');

if (g_form.getValue('category') == 'Networks')
g_form.setValue('u_responsible', 'Sam');

Is 'u_responsible' a reference field?  If so, you'll want to use 'setDisplayValue' to set the friendly name instead of the sys_id.

g_form.setDisplayValue('u_responsible', 'Sam');

need to use getDisplayValue unless the value in the back-end is specifically saying 'Systems'. It is case sensitive.

And then your set value to the exact value (not display value).

You don't have brackets either...and so you could do it like this:

if (newValue == 'Systems'){
g_form.setValue('u_responsible', 'Jack');
}

You've already chosen the field on the client script, so now you can tap in to newValue

Need to look in to DisplayValue script

[Zhivko]

Ok - both fields are strings, so then setDisplayValue should not be necessary, based on what you both say.

I just made the corrections Allen outlined, but that does not seam to change anything. Does it make a difference that the u_responsible field has pre-defined choices?

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === ' ') 
return;

if (g_form.getValue('category') == 'Systems')
g_form.setValue('u_responsible', 'Jack');

if (g_form.getValue('category') == 'Networks')
g_form.setValue('u_responsible', 'Sam');

}
