Help with Limiting Number of Selections in a List field on sctask form

[Sam198]

Hi,

I am trying to limit the selection by user on a list type custom field on sctask form with below Client script, but it removes all the options > it should only allow three selections and as soon as fourth is selected it would give the message and remove the fourth one:

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

    var check = g_form.getValue('u_dropdown').split(',');
    
    if (check.length > 3) {
      
        g_form.showFieldMsg('u_dropdown', 'Only three selection is permitted for this field');
       g_form.setValue('u_dropdown', check[check.length-1]);
    
    }
}

Hi,

don't remove any value as you will have to define logic to know which was the 4th one by comparing old and new value

just show the message near field

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

	var check = g_form.getValue('u_dropdown').split(',');

	g_form.hideFieldMsg('u_dropdown');

	if (check.length > 3) {
		g_form.showFieldMsg('u_dropdown', 'Only three selection is permitted for this field','error');
	}
}

Hi Ankur,

Thanks for the suggestion, however, just one query, this will still allow user to save the form with more than three selection (ignoring the message) - Thats why i was needing to remove the forth selection.

Hi Sam,

That should still be fine.

You can inform the user and let user decide which value to be removed so that only 3 remains.

If my response helped please mark it correct and close the thread so that it benefits future readers.
