g_form removeOption does not work on catalog variable

I am trying to remove an option from a select box on a catalog variable but it does not remove. The script is:

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading) {

          return;

    }

  g_form.removeOption('eai_reviewer_sel_next_task', 'eai_research');

  //g_form.clearOptions('eai_reviewer_sel_next_task');

  //g_form.addOption('eai_reviewer_sel_next_task', 'uat_implement', 'UAT Implementation');

  //g_form.addOption('eai_reviewer_sel_next_task', 'prod_implement', 'PROD Implementation');

}

The g_form.clearOptions and g_form.addOption functions seem to work fine but the g_form.removeOption does not.   I would prefer to not clear all options and add back the ones I need as I need to include the 'none' option and its setMandatory properties.

In case you are still having this problem or someone else stumbles upon this, I was having a similar problem with getControl(), clearOptions() and removeOption() not running on Catalog Tasks or Requested Items when I found this article.


ServiceNow KB: The g_form.getControl method does not work after ordering (KB0547171)


I added the suggested code below to my client scripts and used form.removeOption instead of g_form.removeOption.


var form = typeof g_sc_form != "undefined" ? g_sc_form : g_form;

Once your catalog item is loaded, can you run the same script to remove option on Javascript executor (ctrl+shift_alt+j) and share the result?

Hum, nothing happen when I paste => g_form.removeOption('myVariablename', 'OneValueOfmyQuestionChoices');


in the window...




now the only scope of error is that you are passing wrong arguments in removeOption function . I would cross check that and then double check it again

I opened the javascript executor inserted the code and clicked "Run my code" but nothing seems to happen.   Tried in both Waterfox and Chrome.


I've had this problem in both Fuji and Helsinki.
