Populate Choice List from an Array in Catalog Task Form

[Diorella Angulo]

Hello,

I have a "multi row variable set which" certain columns in my Catalog Item, I was able to get the values from the column named PR Number and put them in an array, the thing is that I want to add these values to a choice list field I have in my Catalog Task from. 

I don't have any Script Include as I'm not familiar with that, but it seems that I need it?

This is my Client Script that applies to Catalog Tasks, and it should be added after save it or update it.

function onSubmit() {
//    //Type appropriate comment here, and begin script below
	
   	if (g_form.getValue('commodity_details')) {
   	    var jsonStr = g_form.getValue('commodity_details');
   	    var objList = JSON.parse(jsonStr);

   	    var part_numbers_array = [];

   	    for (var i = 0; i < objList.length; i++) {
   	        part_numbers_array.push(objList[i].pr_number.toString());
   	    }

   	    g_form.addOption('u_eu_mdr_part_numbers', 'part_numbers_array', 'EU MDR Part Numbers');
  	    alert(part_numbers_array);

   	}
	
}

Any ideas how to achieve this? I really appreciate any help!

I am not sure, why you are running an onSubmit. Do you want to run it on a change of a field value. In that case you should run it on an onChange Client script.

The script can also be improved to

   	if (g_form.getValue('commodity_details')) {
   	    var jsonStr = g_form.getValue('commodity_details');
   	    var objList = JSON.parse(jsonStr);

   	    var part_numbers_array = [];

   	    for (var i = 0; i < objList.length; i++) {
   	        part_numbers_array.push(objList[i].pr_number.toString());
   	    g_form.addOption('u_eu_mdr_part_numbers', objList[i].pr_number.toString(), objList[i].pr_number.toString());
  	    alert(part_numbers_array);
   	    }
   	}

Hi Sanjiv,

It is not working; the dropdown is not populated with the values I need from the MRVS.

Do you think that a script include is needed?

Did you add it inside an onChange client script with field name as the commodity_details?
