Change field options based on another field

[Staxed]

I have found a few answers to similar questions in the past, but for the life of me I can't get this working and am hoping someone might be able to give me example code:

Not sure if I should be using a client script or ui policy for it.

The form is for "Table2" which is extending "Table1" if it matters, the fields are on "Table1"

"Field1" has 4 options, "Field2" has 9 options.  So I'd like to filter out "Field2" based on the value of "Field1".

 Edit: I got it working, but am wondering if there is a way to make this shorter (clearing and adding options instead of removing options would be less rows I think, but can't figure out how to clear the options and then add new ones).  I'd only have 2 add 2 instead of removing 6.

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

if(newValue=='Division')
{
g_form.removeOption('u_hr_location','Location1','Location1');
g_form.removeOption('u_hr_location','Location2','Location2');
g_form.removeOption('u_hr_location','Location3','Location3');
g_form.removeOption('u_hr_location','Location4','Location4');
g_form.removeOption('u_hr_location','Location5','Location5');
g_form.removeOption('u_hr_location','Location6','Location6');
} 
}

Hello,

To add options please use the below syntax:-

g_form.addOption('fieldname','fieldlame','fieldlabel',order);

To clear the variable:-

g_form.clearOption('variable', 'fieldname');

Please mark answer correct/helpful based on Impact.

that worked after I changed g_form.clearOption to g_form.clearOptions

Thank you!
