Remove options from a form on Service Portal (g_form.removeOption() trouble)

Student1 — Tue, 08 Sep 2020 07:40:24 GMT

Hello all, I need some assistance to the following requirement.

I have a record producer on SP, where depending on the category selection, only related subcategories are visible.

For instance, for the category "hardware", only the following subcategories are visible.

However, if I change to another category (for example "software"), all the options are not visible (only the option "--None--" is visible). Then, if I return back to the category "hardware", all the previous options (shown on the first image) are not visible any more as shown below.

I am using a Catalog Client Script (onChange), that gets the value of the field category, and based on that value removes all the unrelated options on the subcategory field. My script looks like this:

Any assistance would be really helpful.

Thank you all in advance.

Hi,

Try using format as below

g_form.removeOption('variable_name','value','label');

So,

g_form.removeOption('subcategory','11','CPU'); //suppose 11 is value while CPU is label.

In addition, you need to use g_form.addOption() as well. So, for your case suppose

if(cat==8)

{

g_form.removeOption('subcategory','11','CPU');

g_form.addOption('subcategory','7'); //choice you want to show

...

}

So, for every .removeOption() you need to use .addOption() to add & make it work independently.

Hi,

While you got the solution, one thing to notice is to remove a option, you need only the fieldname and value. You don't need label.

Ref: https://developer.servicenow.com/dev.do#!/reference/api/orlando/client/c_GlideFormAPI#r_GlideFormRemoveOption_String_String?navFilter=removeOption

Ex: g_form.removeOption('subcategory','11');

But For add, you need 3 arguments fieldname, value, label

Ex: g_form.addOption('subcategory','7','Label'); //choice you want to show

Ref: https://developer.servicenow.com/dev.do#!/reference/api/orlando/client/c_GlideFormAPI#r_GlideformAddOption_String_String_String?navFilter=addOption

Mark the comment as helpful if it helps.

Good info Jaspal.

I found that by adding the value and label ONLY to the removeOption worked great, however, I'd have a blank space below my choice list. Weird.

So I also added the value and label to the addOption function and it worked great.
