Remove just single value from selected values in a list collector

[Nolan4]

Initially a user selects multiple values in a list collector. In this list collector users select devices and we have a functionality already developed where in if a device has already been submitted then we should not allow the user to select that device.

Now the requirement here is just that, we should clearvalue of that last selected device and not clear the entire contents of the list collector. For ex. If 2 values are selected then only the recently selected value(for which already request has been submiited) should be cleared.

Hi,

I don't think you'll be able to address this by removing the "last selected" entry to the list collector, but instead...you'll need to address it at the actual selection itself. Meaning, you would need to identify the sys_id of the selection that needs to be removed and then remove just that one selection. So however you're determining that the device has already been submitted, maybe through glideajax/SI? then you'd use that same sys_id and remove that from the selection of values in the list collector.

Please mark reply as Helpful/Correct, if applicable. Thanks!

Hi Nolan,

Refer this Link

https://www.servicenowguru.com/scripting/client-scripts-scripting/limiting-selections-list-collector...

Try this below code

var myListCollector = g_list.get(collectorName);

var selectedOptions = g_form.getValue(collectorName).split(',');

if((selectedOptions != "") && (selectedOptions.length > 0))

{

         //Remove items

          var index = 0;

          for (var i = 1, leng = selectedOptions.length+1; i < leng; i++){

          myListCollector.removeItem(selectedOptions[selectedOptions.length-i]);

          index++;

          }

}

Please Mark Correct/Helpful answer if it helps you.

Regards,

Kunal.

Thanks for the code. 

It works as below:

var myListCollector = g_list.get(collectorName);

var selectedOptions = g_form.getValue(collectorName).split(',');

if((selectedOptions != "") && (selectedOptions.length > 0))

{

         //Remove items

      //    var index = 0;

      //    for (var i = 1, leng = selectedOptions.length+1; i < leng; i++){

          myListCollector.removeItem(selectedOptions[selectedOptions.length-1]);

       //   index++;

      //    }

}
