Add/Remove options from select box

ceraulo · ‎10-15-2020

Hello!

In a catalog item, i have 2 variables, VAR A and VAR B.

Var A has 2 options - Option 1 and Option 2
VAR B has 2 options, Option 1 and Option 2

The requirement is if the user selects VAR A = Option 1, VAR B will only show Option 2.

//  newValue is VAR_A

if (newValue == 'Option 1') 
        g_form.removeOption('VAR _B', 'Option 1');

    
else if (newValue == 'Option 2') 
	g_form.removeOption('VAR _B', 'Option 2');

This works if I change VAR A to Option 1.
BUT when I change the VAR A selection to Option 2, all of the VAR B values disappear.

I used an On Change catalog client script for this.

Please help!

Thank you.

@ceraulo

please try this updated script

1) first clear all the options

2) then add respective option

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

g_form.clearOptions('VAR _B');

if (newValue == 'Option 1') {
	g_form.addOption('VAR _B', 'Option 2', 'Option 2 Label');
}
if (newValue == 'Option 2') {
	g_form.addOption('VAR _B', 'Option 1', 'Option 1 Label');
}

}

Hi @Ankur Bawiskar

if we clear the options then it is removing None as well,

if the var_b is mandatory even if it is none(added through script) which allows to user submit the form
